Food insecurity and substance use among young adults in the United States

PurposeThe purpose of this study was to examine the association between food insecurity and substance use among young adults aged 18–25 in the U.S. MethodsA cross-sectional online survey was completed by a diverse sample of 1024 young adults (50.2 % female; 62 % non-white; m age = 21.7[SD = 2.26]) between January–April 2022. Logistic regression analyses were used to examine the association between food insecurity and current cigarette use, Electronic Nicotine Delivery System (ENDS) use, cannabis use, alcohol use, and binge drinking controlling for socio-demographic and economic factors, mental health, and experiences of discrimination. ResultsNearly 70 % of participants reported being food insecure over the past year. Substance use was also common: 45.9 % of participants reported current cigarette use, 50.9 % ENDS use, 57 % cannabis use, 65.9 % alcohol use, and 50.4 % engaged in binge drinking in the past two weeks. Being food insecure was associated with greater odds of cigarette use (OR = 2.49, 95 % CI = [1.77, 3.50]), ENDS use (OR = 2.18, 95 % CI = [1.58, 3.01]), cannabis use (OR = 1.73, 95 % CI = [1.26, 2.37]), alcohol use (OR = 1.60, 95 % CI = [1.16, 2.19]) and binge drinking (OR = 1.98, 95 % CI = [1.44, 2.72]), controlling for all other factors. ConclusionFood insecurity may serve as an important indicator of substance use among young adults. Practitioners should consider screening for food insecurity, providing information about food access, and developing interventions to address food insecurity among the young adults with whom they work. Future research should examine these associations prospectively to better understand how food insecurity may contribute to the initiation and/or escalation of substance use.

Flavor & device choices among people who use ENDS: Results from the PATH Study

IntroductionIn guidance published in February 2020, the FDA described their intent to prioritize enforcement against the sale of flavored cartridge-based electronic nicotine delivery systems (ENDS) except tobacco and menthol flavors. This guidance was specific to cartridge-based ENDS and did not apply to other ENDS types or e-liquids sold in the United States (U.S.). It remains unknown if use of certain types of ENDS devices and flavors changed following the publication of this guidance. MethodsThis analysis includes PATH Study data from Wave 5 (W5, 2018-2019) and Wave 6 (W6, 2021) and examines cross-sectional estimates of 1) use of flavored ENDS and 2) use of different device types. All analyses in this study were stratified by self-reported age (youth – aged 12-17 years at W5 and aged 14-17 years at W6, and adults – aged 18-20, 21-24, and 25+). Analyses were conducted in 2023-2024. ResultsAmong adults aged 21 years and over, there were significant increases in the use of menthol or mint flavored ENDS. There were no substantial changes in flavors of ENDS used among youth or adults aged 18-20 years. Among all age groups, the use of cartridge-based ENDS was lower in 2021 than 2018–2019, with a notable shift to disposable-style ENDS. ConclusionsFederal-level tobacco control actions taken in the U.S. in early 2020 prioritized enforcement against “any flavored, cartridge-based ENDS product (other than a tobacco- or menthol-flavored ENDS product)”. Based on this analysis, there was a shift following the policy to menthol or mint-flavored ENDS and disposable-style ENDS.

Using implementation science to evaluate the implementation of patient-reported outcome measures (PROMs) in a clinical heart failure care setting

BackgroundPatients with heart failure can experience poor quality of life, recurring hospitalizations, and progressive disease symptoms. Patient-reported outcome measures (PROMs) include patients’ voices in clinical care by assessing patient symptoms, function, and quality of life. In 2022, PROMs were implemented into the electronic health record system (Epic) at a large academic hospital in Toronto, ON. The purpose of this study was to use implementation science frameworks to systematically evaluate the uptake and integration of PROMs into clinical heart failure care. MethodsThe Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework guided the mixed-methods, one-year quality improvement project. Data sources included clinician use of PROMs, patient-level data on completed PROMs, and semi-structured interviews with clinicians. The PROM was the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) which captures four domains related to heart failure: symptom frequency, physical limitations, social limitations, and quality of life. Quantitative data was analyzed using descriptive statistics and qualitative data was analyzed using behaviour change frameworks and latent content analysis. ResultsOver one year, more patients were assigned to PROMs, a higher proportion of patients completed PROMs, and approximately 80% of patients had high KCCQ-12 scores. Clinicians experience barriers related to attention and decision processes, environmental context, and professional role for integrating PROMs into practice. Suggested resources include adding language licenses for PROMs translations, reducing cognitive load for clinicians assigning and interpreting PROMs in Epic, and champions modelling PROMs in practice. ConclusionsThis study demonstrates the benefit of using implementation science frameworks to evaluate the implementation of PROMs in practice and to provide actionable recommendations to health systems.

Resonant tunneling properties of laser dressed hyperbolic Pöschl-Teller double barrier potential

We examine the resonant tunneling properties of the laser-dressed hyperbolic Pöschl-Teller double quantum barrier structure. We use the non-equilibrium Green's function method to investigate structure parameters and electric field bias on the transmission properties of the system. The transmission probabilities and resonance energy levels are significantly influenced by the well widths and barrier heights. The barrier height increases, resonance energy levels shift toward higher values, and the resonance peak width narrows, leading to sharper and more selective tunneling behavior. Our results show that increasing the electric field bias leads to a decrease in the transmission probability at the first resonance peak, but this effect is not as strong for the subsequent peaks. Moreover, we find that changes in the laser field's parameter and structure parameters allow for fine control over the electronic spectra, allowing for modifications like red or blue shifts based on particular needs. The significance of comprehending the interaction among structural factors, external fields, and transmission qualities in quantum barrier structures is highlighted by our research, providing valuable information for the development and enhancement of electronic and optoelectronic systems with customized functionality. Our findings show the laser field has a considerable impact on resonant tunneling properties, opening the door to new device applications.

Consanguinity and Occurrence of Monogenic Diseases in a Single Tertiary Centre in Riyadh, Saudi Arabia: A 2 Years Cross-Sectional Study.

Consanguinity, or the practice of marrying close relatives, is a common cultural tradition in Saudi Arabia, with rates among the highest in the world. This practice has significant implications for the prevalence and distribution of major single genetic defects and chromosomal abnormalities within the Saudi population. Herein, using the BESTCare electronic medical record system (designed to streamline hospital operations, enhance patient care, and improve the overall efficiency of healthcare services; bestcare.ezcaretech.com) in a single tertiary centre, King Abdullah Specialized Children Hospital (KASCH) in Riyadh, Saudi Arabia, we performed a cross-sectional study for all patients referred to the hospital from the 1st January 2020 until 1st January 2022. The present study, which included 1100 individuals, found a high prevalence of consanguinity (64%) and a significant proportion of third-degree relatives (69%). The mean age of participants was 12.24 years, and the diagnostic rate using advanced molecular genetics techniques was 45%, with whole exome sequencing (WES) being the most common method (43%). The study also noted a significant delay in diagnosis for more than a year in 16% of cases, with a common neurodevelopmental phenotype (18%). In conclusion, we revealed the prevalence of consanguineous marriages in the KASCH hospital in Riyadh, Saudi Arabia. We also highlighted the most frequently referred phenotype. These findings are consistent with previous research on the prevalence and impact of consanguinity on rare genetic disorders.

Minimizing unnecessary proBNP blood tests: an evaluation of a pop-up form implementation in general practice

Objective To evaluate the impact of a compulsory pop-up form on the ordering pattern of proBNP blood tests by general practitioners in the Capital Region of Denmark. Design A follow-up study comparing the average number of proBNP tests ordered before and after the implementation of an intervention. Setting and subjects From 2016 to 2021, the average number of proBNP tests increased by over 300%. In March 2022, a compulsory pop-up form was introduced in the electronic request system (WebReq), requiring general practitioners to select one of three indications for ordering proBNP, as recommended by the Danish Society of Cardiology. The study included 528 general practitioners in the Capital Region of Denmark, with data available from January 2020 to 2023, encompassing 83,576 proBNP results from 56,645 patients. Main outcome measure The average number of proBNP tests ordered per month and the median level of proBNP before and after the intervention. Results Following the intervention, the average number of proBNP tests per month decreased by 60% over a 22-month follow-up period. The highest reduction was seen among general practitioners who previously ordered the most tests (≥3 per 1000 biochemical tests). In this group, the median proBNP level increased from 12.1 pmol/L before the intervention to 13.5 pmol/L after the intervention (p < 0.0001). Conclusions This study demonstrates a significant decrease in the number of proBNP requests from general practitioners in the Capital Region of Denmark after the introduction of a pop-up form in the requisition system containing the current guidelines.

Improving the OncotypeDX ordering process in patients with ER+ HER2- early-stage breast cancer: A longitudinal QI project.

292 Background: Use of the 21-gene recurrence score assay, OncotypeDX, is an NCCN category 1 recommendation to define adjuvant treatment planning for patients with hormone receptor positive (HR+), HER2 negative (HER2-) early-stage breast cancer. The assay is a key part of the decision-making process to define who may benefit from adjuvant chemotherapy with delays in testing that may impact patient care and loss of trust between oncologists and patients. Methods: We first created a comprehensive process map of the system in place to order OncotypeDX and met with an interdisciplinary team to determine the best area of intervention. A nurse coordinator from medical oncology took over OncotypeDX ordering in September 2023. To determine impact, we obtained data on OncotypeDX orders (N=473) sent by medical oncologists at Washington University in St. Louis between 9/2022 and 4/2024. We determined the delay between specimen collection and OncotypeDX order and the time from order to delivery of the report in the electronic medical record system. We then assessed our outcome measure, the date of the first office visit after surgery and whether patients had an OncotypeDX test result at that visit for 270 consecutive orders spanning pre- and post-intervention (6/2023 – 4/2024). Results: We used a p-chart to assess our outcome measure of OncotypeDX availability at the time of office visit with medical oncology, a key metric for both treatment planning and patient trust. We observed a positive trend of seven data points in the most recent data when mapping the 270 patients by consecutive groups of 10. In our most recent data pull from April 2024, 85% (22/26) of patients who required an OncotypeDX had one completed at the time of office visit, in comparison to 50% (20/40) in August 2023, the month prior to the intervention. We used XmR and S charts to determine impact on delay from specimen collection to OncotypeDX order, which showed increased precision and a trend of decreased delay after implementing the nurse coordinator. The overall delay decreased from an average of 28 days pre-intervention (9/2022-9/2023) to 24 days in the most recent post-intervention data (3/2024). Average time between order and delivery, our balancing measure, decreased during these time periods from 16 days to 13 days. Conclusions: Implementing a nurse coordinator improved delays in specimen collection to order and order to receipt. This intervention increased the percentage of patients who had an OncotypeDX result at the time of office visit with medical oncology after surgery.

Study of Optoelectronic, Magnetic, and Thermoelectric Properties of Sr2XOsO6 (X = Y, Lu, Sc) Double Perovskites for Spintronic and Data Storage Devices

Advancement in electronic device miniaturization coupled with the precise control over their electromagnetic and transport properties, holds great promise for realizing practical quantum computing devices. Double perovskites, known for their stability, non-toxicity, and spin-polarized characteristics, are particularly appealing for spintronics applications. In this communication, we investigate the role of 6d-electrons of Os in regulating the magnetic properties in Sr2XOsO6 (X = Y, Lu, Sc) using theoretical methods with the WIEN2k code. The computed formation energies (-3.04, -2.91, and -2.82 eV) confirm the thermodynamic stability of these compositions. Analysis of the band structures and DOS exhibit ferromagnetic semiconducting character, elucidated through exchange constants and energies. This computation highlights the essential role of basic hybridization processes, crystal field effects, and exchange energy in generating ferromagnetic character driven by electronic spin. The analysis of optical behavior against photon energy (eV) reveals the maximum absorption in the UV region. Furthermore, the calculated values of σ/τ, ke/τ, S, χ, PF, and ZT in the temperature range of 200-800 K highlight the potential of these compounds for thermoelectric applications. This comprehensive analysis underscores the suitability of Sr2XOsO6 (X = Y, Lu, Sc) for advanced electronic and spintronic technologies.

Ti3C2Tx MXene coated 3D ordered macroporous germanium anodes for Li-ion batteries with enhanced cycling stability and fast Li-ion mobility

The current trend in electronic device development and electric vehicle technology has resulted in a growing need for negative electrode materials that possess high capacity and quick Li-ion transport properties. Ge-based materials are considered the very promising candidates owing to their high theoretical capacity and facile alloying reaction with Li. In order to enhance the rate of Li-ion diffusion and account for the volume change of over 300%, a Ti3C2Tx MXene coated 3D ordered macroporous germanium (3DOM Ge@MXene) structure was successfully developed. The 3DOM Ge@MXene provides a 1490 mAh g−1 initial reversible capacity at 0.32 A g−1. Additionally, after 100 cycles, it displays a consistent cycling ability of 1034 mAh g−1. The MXene coating also improves the material's Li-ion rapid transfer performance, with Li-ion diffusion coefficient of 1.35 × 10−10 cm2 s−1 for anodic and 2.2 × 10−10 cm2 s−1 for cathodic.

Oxygen vacancy induced electrical conductivity enhancement in Ca-doped BiFeO3 thin films

Bismuth ferrite, recognized for its exceptional physical properties as a multiferroic material, has recently attracted considerable attention due to its high domain wall conduction. However, challenges in further improving domain wall conductivity and magnetoelectric coupling hamper the practical application of pure-phase BFO thin films. Addressing these limitations, we successfully synthesized Bi1-xCaxFeO3 thin films on LaAlO₃ (001) substrates with varied calcium (Ca) doping levels (x = 0–0.3) through pulsed laser deposition. Our experimental data demonstrate a direct relationship between the films' electrical conductivity and the prevalence of oxygen vacancies (OV). An upward trend in both OV density and electrical conductivity emerges with incremental Ca doping, peaking at x = 0.2. Beyond this doping threshold, a further increase in Ca concentration inversely affects OV density and electrical conductivity. These insights suggest that fine-tuning OV concentration in Ca-doped BFO thin films can significantly modulate their electrical properties, paving the way for the advancement of bismuth ferrite-based electronic devices.

Alkali-Stable Metal-Organic Frameworks with Enhanced Electroconductivity for Black-Brown Electrochromic Energy Storage Smart Window.

Metal-organic frameworks (MOFs) deliver potential applications in electrochromism and energy storage. However, the poor intrinsic conductivity of MOFs in electrolytes seriously hampers the development of the above-mentioned electrochemical applications, especially in one MOF electrode. Herein, a new Ni-based MOF (denoted Ni-DPNDI) is proposed with enhanced conductivity by π-delocalized DPNDI connectors. Predictably, the obtained Ni-DPNDI MOF achieves a conductivity of up to 4.63 S∙m-1 at 300 K. Profiting from its unique electronic structure, the Ni-DPNDI MOF delivers excellent electrochromic and energy storage performance with a great optical modulation (60.8%), a fast switching speed (tc = 7.9 s and tb = 6.4 s), a moderate specific capacitance (25.3 mAh·g-1) and good cycle stability over 2000 times. Meanwhile, energy storage capacity is visual by the coloration states of Ni-DPNDI film. As a proof of the potential application, a large-area (100 cm2) electrochromic energy storage smart window is further designed and displayed. The strategy provides an interesting alternative to porous multifunctional materials for the new generation of electronic devices with diverse applications.

Cardiac Implantable Electronic Device Patient Follow-Up: Assessment of U.S. Practice

BackgroundA 2015 expert consensus statement recommended that patients with cardiac implantable electronic devices receive remote monitoring and at least 1 in-office evaluation annually. ObjectiveWe examined whether patients who underwent implantation of a new cardiac implantable electronic device received care concordant with consensus statement recommendations. MethodsWe examined the rate of follow-up office visits and remote monitoring for 211,346 Medicare beneficiaries with an implantation of a new cardiac implantable electronic device between October 2015 and December 2020. We also assessed the characteristics of patients receiving follow-up care. ResultsWithin 16 weeks of implantation 77.8% of patients were seen in-office for a post-operative evaluation. The percentage of patients seen in office was 85.9% in the first 12 months, with 64.2% of patients seen in office every two years post-implantation, respectively. Following implantation, the percentage of beneficiaries receiving remote monitoring in the first 91 days was 14.7%, with 4.4% patients receiving remote monitoring every 91 days post-implantation within the first year. Patients who were ≥ 85 years old, non-white, or of lower income were less likely to receive office visits post-implantation. ConclusionsWhile most Medicare beneficiaries were seen in-office in the year following a new implant, the percentage of beneficiaries with an in-office visit declined in subsequent years. Fewer than five percent of beneficiaries had remote monitoring at the frequency recommended by the expert consensus statement. Patient demographics, including older age, non-white race, and lower income were associated with a lower likelihood of receiving care concordant with consensus statement recommendations.

Ten questions about infective endocarditis

Infective endocarditis (IE) is an infective process involving the endocardium and, more frequently, the native heart valves, valvular prostheses and cardiac implantable electronic devices. IE can manifest with various non-specific symptoms making the diagnosis challenging. This condition is associated with high in-hospital and long-term mortality. Therefore, it is particularly important to prevent it by implementing an adequate antibiotic prophylaxis especially in patients at high risk undergoing invasive procedures. Moreover, it is pivotal to promptly diagnose IE, detect the presence of local and systemic complications, establish appropriate antibiotic therapy and identify the indication and timing for surgical treatment. In this focused review, we will provide answers to the most common questions regarding the epidemiology, causes, prophylaxis, diagnosis and antibiotic and surgical treatment of IE.

Phase transition behavior of (MoTe2)xSb1-x thin films based on flexible PEEK substrates

Flexible information memory played a key role in flexible electronic devices and smart wearables. This paper was focused on the effect of flexible deformation on the properties of (MoTe2)xSb1-x nano-phase-change films based on PEEK substrates. By placing the films at the finger, wrist, back of the hand and elbow and bending them, the resistance values showed periodic fluctuations with bending but the changes were not significant. After 100,000 bending cycles and 4,000 s of vibration, the films successfully achieved the transformation from a shapeless to a structured state. The stress caused by bending and vibration affects the surface roughness of the flexible film and weakens the adhesion between the film and the substrate. Flexible (MoTe2)0.07Sb0.93 film electronics were prepared, and the phase change memory devices could realize reversible transitions between SET and RESET states with 100 ns pulse widths in the flat state, after 100,000 bending cycles, and after 4,000 s of vibration. These findings indicated that (MoTe2)0.07Sb0.93 films based on flexible PEEK substrates had promising applications in the field of flexible phase change memory.

Investigation and Demonstration for immunoassay technology based on impedance Amplifies of magnetic and dielectric microbeads

BackgroundBead-based immunoassays typically require researchers to perform the analysis in a laboratory setting, involving complex processing procedures, most of the time, constant potential or current instruments are used to measure the bio-impedance change. However, almost all biological materials are decorated on the electrode surface to obtain the maximum sensitivity, resulting in difficulty to clean, separate, and other applications of fixed bead-based immunoassay. ResultWe present an innovative unfixed bead-based immunoassay technology that utilizes electrical impedance characteristics, offering the advantages of being rapid, portable, miniaturized, and cost-effective. This technique which is known as impedance-enhanced electrochemical immunoassay (IE-ECIA) employs antibody-coated magnetic beads (MBs) and dielectric beads (DBs) linked to antigens for quantitative with miniaturization electronic devices, which has been successfully applied in an immune impedance sensor for detecting the dengue virus (DENV), which is an affordable test with a low-cost microfluidic impedance biosensor combined with immune magnetic and dielectric micro/nanobeads for antigen detection. HighlightThe proposed immunoassay technology introduces a novel microfluidic platform incorporating magnetic and dielectric beads alongside with an electrochemical impedance biosensor, therefore facilitating continuous-fluid quantitative analysis. This innovative and unconventional approach leverages free-motion multiplex beads housing magnetic and dielectric bead-bound antigens within a simple linear microchannel of microfluidic chip architecture, making the high-through measurements more efficient, enhanced electrochemical immunoassay (ECIA) signals of bio-on-magnetic-beads (BOMB). This advancement holds significant potential for enhancing diagnostic capabilities for emerging infectious diseases within clinical environments, thereby bolstering rapid detection capabilities and aiding in the advancement of novel pharmaceuticals, benefiting all the stakeholders.

Enhanced energy storage performance of tungsten bronze structured BaNb2O6-modified (Bi0.5Na0.5)TiO3 ceramics

The rapid development of the electronic devices and increasing attention to environmental problems have put forward a huge demand for high-performance lead-free dielectric energy storage ceramics. In this work, tungsten bronze structured BaNb2O6 (BN) modified perovskite structured (Bi0.5Na0.5)TiO3 (BNT) ceramics, BNT-xBN (0 <x< 0.15), were prepared to optimize the energy storage performance of BNT. The results show that the lattice distortion and dielectric relaxation behavior of BNT ceramic can be induced by BN addition. Meanwhile, the introduction of tungsten bronze structured BN results in the grain refinement and the increasing of resistivity, thereby significantly enhancing the electrical breakdown strength (Eb). Accordingly, the BNT-0.1BN ceramic displays good energy storage performance with high recoverable energy density (Wrec ~ 3.41J/cm3) at an great Eb of 358 kV/cm, accompanied by the wide temperature stability at 30-150 °C (Wrec varies within ±12.8%, efficiency (η) varies within ±6.7%). The enhanced energy storage performance demonstrates that introducing tungsten bronze structure is a feasible method to prepare high-performance perovskite energy storage ceramics.

Multi-objective topology optimization and numerical investigation of heat sinks based on triply periodic minimal surface lattices

In thermal management applications, such as heat sinks (HSs) for electronic devices, cellular materials have extensively been employed. In recent years, there has been a growing attention towards employing topology optimization for enhancing hydraulic and heat transfer performance of HSs by optimizing their topology. The utilization of triply periodic minimal surface (TPMS) based structures presents distinctive prospects for customizing the design and performance of HSs. However, their potential remains unexplored in the context of customizing additively manufactured porous optimized HSs. Consequently, there is a need for research aimed at examining their coupled hydraulic and thermal performance. Density mapping approaches are used to build a variable density TPMS-based HSs from the output of topology optimization by applying the TPMS level-set equations that relate relative density and the level-set constant. In this work, a relative density mapping methodology is applied to thermo-fluid optimization problem to design a TPMS-based convective cooling system. An in-house MATLAB code was developed to perform a multi-objective topology optimization. After that, uniform and variable density (mapped from topology optimization results) TPMS-based HSs are analyzed using Star-CCM+ CFD software to investigate their hydraulic and heat transfer performance. An experimental setup was established, and the numerical results were validated using uniform TPMS-based heat sinks. Results showed that incorporating TPMS with topology optimization has a great potential in thermal management applications as pressure drop across the heat sink was reduced while maintaining the performance.

First-principles simulation of electronic properties of MoB/Si3N4 superlattices via machine learning

MBene materials and Si3N4 materials have excellent properties, but there are still many technical bottlenecks in the preparation of high-performance and flexible structure electronic device materials. In this paper, MBene is combined with Si3N4 materials to form a superlattice structure, which is composed of six superlattice heterostru ctures. Firstly, the first-principles method was used to study the electronic properties of MBene/Si3N4 superlattice materials. The results show that with the increase of stacking times, the material structure becomes more stable, and the interlayer electrons are transferred from the MoB layer to the Si3N4 layer. Second, in the machine learning part, the Extreme Gradient Boosting (XGBoost) algorithm and the Convolutional Neural Network (CNN) algorithm were used to predict the density of states of six superlattice heterojunctions through ensemble learning, and it was found that the best prediction results were achieved when the input data with a combination of global descriptors and local descriptors were used. The lowest MAE is only 0.03, which not only indicates that the predicted density of states model is excellent, but also proves that the more refined the characterization of the surrounding environment of the atom, the more accurate the prediction of the density of states of the material and the higher the generalization performance of the prediction model.

Integrating dual heat sources to enhance thermoelectric generator power output

The escalating demand for sustainable power sources for wearable electronics necessitates innovative solutions. This study tackles the challenge of sustainably powering wearable electronics, addressing the limitations of traditional batteries. The approach utilizes a thermoelectric generator with a flexible and stretchable substrate that integrates the photothermal effect and human body temperature as a heat source. A unique strategy is employed to achieve this, involving the combination of 10 g of polydimethylsiloxane, 0.5 g of carbon nanotubes powder, 1 g of base curing agent, and 1.15 g of ethyl acetate mixture used as the novel substrate material. The proposed composite substrate is paired with p-type and n-type thermoelectric legs of bismuth antimony telluride (Bi0.4Sb1.6Te3) and bismuth selenium telluride (Bi1.7Te3.7Se0.3), respectively. This innovative design ensures high flexibility, stretchability, and conformability, facilitating seamless integration into wearable electronic devices. Experimental validation and simulation-based studies reveal a power density of 166.29 μW/cm2, sufficient for powering small-scale wearable electronics. The thermoelectric generator coupled with a novel composite substrate showed 65.6 % stretchability, further underscoring its durability and adaptability. The critical finding lies in the dual heat source integration, which collectively boosts power output and ensures year-round performance, pushing the boundaries of wearable energy harvesting technologies.
