The synergistic effect of rapid cooling process and S-GNP promoted electroactive phase content up to >97% (β + γ) of PVDF and assisted in tuning the crystallinity, tensile and dielectric properties of the PVDF/S-GNP nanocomposite (S-PGN-X) films. A flexible piezo-capacitance based pressure sensor offered an excellent response, quick recovery and high sensitivity (1.25 kPa−1) with a wide pressure sensing range (0.25–50 kPa). The sensor was integrated into a shoe sole to monitor the heel and toe pressure. Further, the S-PGN-X based triboelectric device showed excellent performance with a voltage output of >120 V and 175 μW/cm2 power density. The output of the device was sufficient to glow the LED lights, suggesting that it can be used as a sustainable power source for portable devices. Moreover, S-PGN-X based piezoelectric nanogenerator generated a voltage output of ∼19 V upon repeated application of pressure with a good power output of 1.35 μW/cm2. The piezoelectric nanogenerator could charge up a 3.3 μF capacitor up to 1.1 V under repeated finger impartation. Overall, the multifunctional S-PGN-X film with self-poling characteristics showed excellent piezo-capacitance, piezoelectric and triboelectric performance, which makes it a potential material for sensors, energy harvesting and portable electronic devices.

From Biological Source to Energy Harvesting Device: Surface Protective Ionic Liquid Coatings for Electrical Performance Enhancement of Wood-Based Electronics.

This study explores task-specific ionic liquids (TSILs) in smart floor systems, highlighting their strong electrical rectification abilities and previously established wood preservative properties. Two types of TSILs, featuring a "sweet" anion and a terpene-based cation, were used to treat selected wood samples, allowing for a comparison of their physical and electrical performance with untreated and commercially treated counterparts. Drop shape analysis and scanning electron microscopy were employed to evaluate the surface treatment before and after coating. Near-IR was used to confirm the presence of a surface modifier, and thermogravimetric analysis (TGA) was utilized to assess the thermal features of the treated samples. The different surface treatments resulted in varied triboelectric nanogenerator (TENG) parameters, with the molecular structure and size of the side chains being the key determining factors. The best results were achieved with TSILs, with the instantaneous voltage increasing by approximately five times and the highest voltage reaching 300 V under enhanced loading. This work provides fresh insights into the potential application spectrum of TSILs and opens up new avenues for directly utilizing tested ionic compounds in construction systems.

Super-Low Friction Electrification Achieved on Polytetrafluoroethylene Films-Based Triboelectric Nanogenerators Lubricated by Graphene-Doped Silicone Oil.

The novel proposal of Wang's triboelectric nanogenerator (TENG) has inspired extensive efforts to explore energy harvesting devices from the living environment for the upcoming low-carbon society. The inevitable friction and wear problems of the tribolayer materials become one of the biggest obstacles for attaining high-performance TENGs. To achieve super-low friction electrification of the TENGs, the tribological and electrical behaviors of the sliding-mode TENGs based on polytetrafluoroethylene (PTFE) films and metallic balls under both dry friction and liquid lubrication conditions were investigated by using a customized testing platform with a ball-on-flat configuration. Most interestingly, a super-low friction coefficient of 0.008 was achieved under graphene-doped silicone oil lubrication. The corresponding wear rate of the PTFE film was drastically decreased to 8.19 × 10-5 mm3/Nm. Simultaneously, the output short-circuit current and open-circuit voltage were enhanced by 6.8 times and 3.0 times, respectively, compared to the dry friction condition. The outstanding triboelectrical performances of the PTFE film when sliding against a steel ball are attributed to the synergistic lubricating effects of the silicone oil and the graphene nanosheets. The current research provides valuable insights into achieving the macro-scale superlubricity of the TENGs in practical industrial applications.

Optical absorption spectrum of impurities added CdS materials exhibit blueshift. Moreover, enhanced absorption and upgraded conductivity along with increasing refractive index of selected materials emphasize their potential uses in high energy UV photonics, sensors, spintronics, optoelectronics and energy harvesting devices.

Piezoelectric self-power supply driven by ferroelastic host–guest supramolecule with considerable electromechanical conversion capability

Crown ether supramolecules with host–guest structure bring the two most advanced application categories, namely information storage and energy conversion. The former was awarded the 2016 Nobel Prize in Chemistry, but the latter has thus far exhibited suboptimal electromechanical conversion properties. Enhancing the piezoelectric properties of such supramolecules has become a continuous and fascinating challenge. Here, we have made breakthrough progress in a crown ether-based ferroelastic supramolecular rotator [(N,N-dimethylethylenediammonium)(18-crown-6)]BF4 (MCBF) under the guidance of the crystallographic engineering. MCBF shows the record-high piezoelectric voltage coefficient (∼1000 × 10-3 V m N−1) and piezoelectric coefficient (∼46.1 pC N−1), which represent respectively improvements of 41.7% and 9.8% compared to the latest reported counterpart (J. Am. Chem. Soc. 145 (2023) 3187–3195). Notably, theoretical calculations elucidate that the ferroelasticity of MCBF contributes to its large piezoelectric response. In addition, an energy harvesting device is successfully achieved for the first time to evaluate its potential as a piezoelectric self-power supply, and LEDs are successfully lit by harvesting mechanical energy. This work takes an important step towards artificial supramolecular machines and arouses broad interest in self-powered flexible devices.

Power generation via spontaneous water evaporation is considered as one potential solution to the energy and pollution issues in very recent years. The efforts to harvest this type of green energy have been made in the previous works, which proved the different functional materials can be used for the energy harvesting device. However, few studies focused on the capillary flow of liquid inside the devices, which should be a key factor in the process of electricity generation. In this work, four carbon black film devices with different geometries are designed and fabricated. From the experimental test, it is found the optimization of device geometry is an efficient approach for improving the electricity output performance, and an increase of 200% in the generated open-circuit voltage can be achieved. In addition, three different types of capillary grooves are etched on the Al2O3 substrates through ultrafast laser micromachining, which is to further improve the liquid capillary flow inside the devices and reduce the flow losses. A voltage output of 188 mV can be realized in the device with the fractal tree-like capillary grooves, which obtains a 652% improvement compared to the original one.

The potential application of the triboelectric nanogenerator in the new type futuristic power grid intelligent sensing

AbstractTo meet the requirements of power grid operation control, constructing an extensive sensor network in the power grid is a future development trend. However, due to the high cost, the difficulty of continuous power supply for a long time, the large amount of energy consumption, and the environmental problems caused by abandoned batteries, the traditional power supply mode based on batteries for sensors is inconsistent with China's goal of carbon peak and carbon neutrality. It cannot meet the needs of the future grid. Therefore, it is significant to solve the energy supply problem of numerous sensors to promote the construction of new power grid and improve the utilization rate of renewable energy. As an emerging energy harvesting device, triboelectric nanogenerators (TENG) are suitable for developing self‐powered sensors and powering low‐power sensors due to their mall size, high efficiency, low cost, and environmental friendliness. At the same time, due to the abundant, stable, and widely distributed magnetic field around the equipment in the grid, it can provide continuous excitation for the TENG. Therefore, applying magnetic field energy‐harvesting TENG in the future power grid has a broad development prospect. This paper analyzes the development trend and the crucial problems facing the power grid in the future. We review the research and application of TENG based on the magnetic field in recent years and explain the mechanism of TENG in detail. Finally, the application prospect of TENG in the future power grid has been prospected. This paper can provide a reference for applying magnetic field energy harvesting triboelectric nanogenerators in future power grids.image

Clitoria ternatea flower extract: Biopolymer composite-based triboelectric nanogenerator as a self-powered smart counter

The development of biopolymers-based high-performance triboelectric nanogenerators (TENGs) for powering innovative electronics is crucial for green energy technologies. Herein, a novel TENG composed of polyvinyl alcohol (PVA) functionalized with electron-donating groups from Clitoria ternatea (CT) flower extract is proposed. The compatibility of composite film in energy harvesting devices is tested through various characterizations, including structural, surface, electrical, and bioassay. Interestingly, the enhanced tribopositivity of the composite is attributed to intermolecular hydrogen bonding between taraxerol and PVA, substantiated by Hartree-Fock-DFT calculated vibrational spectrum, frontier molecular orbital energy gap, and electrostatic potential maps. TENG with PVA-CT: Polyurethane generated an open-circuit voltage (VOC) of 14.8 times and short-circuit current (ISC) of 32.7 times, more significant than PVA TENG and several bio/non-biodegradable tribonegative polymers. The long-term stability test of PVA-CT TENG is confirmed by an observation of constant VOC for eight consecutive months. Additionally, humidity studies reveal that output increases with an increase in relative humidity of 30–100%. Further, the PVA-CT TENG is efficient in charging capacitors, powering LEDs, and acts as a self-powered smart counter. Overall, this study contributes new insights into developing eco-friendly synergistic materials for TENG fabrication and extending its applications in the Internet of Things, facilitating to build of futuristic smart cities.

Rational Design Strategy for Triboelectric Nanogenerators Based on Electron Back Flow and Ionic Defects: The Case of Polytetrafluoroethylene

AbstractThe lack of theoretical understanding of triboelectrification has hindered the development of energy harvesting technologies like triboelectric nanogenerators. Focusing on polytetrafluoroethylene, a material with a strong triboelectric output, a model predictive of its triboelectric behavior, driving the development of improved nanogenerators are formulated. With a combined computational‐experimental approach it is shown that defluorination enhances polytetrafluoroethylene nanoscale triboelectric charging. Then a model, explaining the macroscale triboelectric output as determined by the competition of two mechanisms is developed. Defluorination enhances charging while also reducing the interface gap, favoring the backflow of electrons, and possibly reducing charging. However, numerical analysis shows that backflow is negligible, aligning with the prediction of increased triboelectric output. By building triboelectric nanogenerators with defluorinated polytetrafluoroethylene samples, achieved by X‐ray irradiation, a one‐order‐of‐magnitude output increase is demonstrated. The predictive models, supported by experiments, lead to an improved strategy for designing effective energy harvesting devices and new applicative breakthroughs.

Low-frequency vibration is widespread in nature. Vibration energy harvesting is considered to be a reliable and sustainable method to achieve continuous power supply. It is a feasible method to design an energy harvesting system of the bio-inspired mechanical structure to improve the efficiency of energy harvesting. A hybrid energy harvester piezoelectric–electromagnetic that mimics the flapping wing motion of the Diptera insect. The biomimetic energy harvesting device consists of two piezoelectric cantilever beams structure with the mass block installed, which mimics the flapping movement mechanism of the Diptera insect. The intermediate part of this harvester inspired by the insect skeleton and muscle structure of the Diptera insect is composed of magnetic levitation coupled repulsion structure, which is easily affected by vibration and changes greatly, to realize electromagnetic energy harvesting. The ‘click’ mechanism of the Diptera insect is constructed by storing energy in springs to improve the performance of energy harvesting devices. The hybrid energy harvesting device realizes piezoelectric–electromagnetic energy harvesting with multiple energy outputs at one excitation input. A dynamic model of the proposed energy harvester is constructed based on the electromechanical coupling characteristics. The modal analysis and structure optimization of this device is realized by the finite element method (FEM). The FEM simulation and experimental results can verify that under the low-frequency excitation of 3 Hz, the maximum output power of the designed harvester reaches 12.33 mW in the low-frequency environment.

Pouch-sealing as an effective way to fabricate flexible dye-sensitized solar cells and their integration with supercapacitors

The scientific interest in integrated energy harvesting and storage (HS) devices has increased exponentially in the last decade since they represent an optimal solution to power portable electronic devices and low consuming Internet of Thing (IoT) sensor nodes. The integration of energy storage devices with photovoltaics can allow to avoid problems such as continuous battery replacement and periodic maintenance, reducing overall costs. In this context, dye sensitized solar cells (DSSCs) integrated with a supercapacitor represent the best choice in terms of lifetime, charge-discharge efficiency, and simplicity of connection avoiding electrical signal conditioning between the two devices. DSSCs have many similarities with supercapacitors, with the only aspect that remains uncovered being the sealing of the device. Herein we propose a common vacuum sealing technology for the integration of a supercapacitor and a DSSC made with shared current collectors, to maximize the integration between the two technologies. The HS device showed a maximum overall photon to electrical conversion and storage efficiency (OPECSE) of 6.10% under only 0.1 SUN illumination, thanks to the high photoconversion efficiency showed by the pouch sealed DSSC, equal to 6.62%. The HS device showed a high stability under bending condition and repeated photo-charge/discharge cycling.

Hydrophobic Chain-Induced Conversion of Three-Dimensional Perovskite Nanocrystals to Gold Nanocluster-Grafted Two-Dimensional Platelets for Photoinduced Electron Transfer Substrate Formulation.

Considering the augmentation of new generation energy harvesting devices and applications of electron-hole separation therein, conversion of 3D cubic CsPbBr3 perovskite nanocrystals into 2D-platelets through ligand-ligand hydrophobic interactions has been conceived here. Cationic surfactants with various chain length coated the gold nanoclusters (AuNCs) that interact with oleic acid (OA) and oleylamine (OAm) coated 3D CsPbBr3 nanocrystals to disintegrate the crystallinity of the perovskites and reformation of AuNC-grafted 2D-platelets of unusually large size. The planar perovskite-derivatives act as an exciton donor to the embedded AuNCs through photoinduced electron transfer (PET). This process is controlled by the optimum surfactant chain length. Transient absorption spectroscopy shows that the fastest radical growth time (4 ps) was with the 14-carbon containing tail of the surfactant, followed by the 16-carbon (45 ps) and the 12-carbon (290 ps) ones. PET is administered by the energy gaps of the participating candidates that control the transition dynamics. Our findings can be a potential tool to develop metal nanocluster-based hybrid 2D perovskite-derived platelets for optoelectronic applications.

Herein, we exploit these properties to fabricate a photo-assisted supercapacitor serving the dual functions of energy harvesting and electrochemical energy storage in a single device. The device utilized stable inorganic Cu3Bi2I9 perovskite material in fabricating a Cu-perovskite photoactive electrode. A novel HPvA gel electrolyte was synthesized and sandwiched between two Cu-perovskite photoactive electrodes, to obtain a Cu-perovskite photo-assisted supercapacitor. The HPvA gel electrolyte was characterized by fourier-transfrom infrared spectroscopy (FTIR), linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS). The Cu-perovskite photoactive electrode was characterized by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). We characterized the electrochemical and photo-electrochemical energy storage performance of the Cu-perovskite photo-assisted supercapacitor by cyclic voltammetry (CV) and EIS. The device recorded 127 % energy density augmentation, at a scan rate of 0.01 V/s. The Cu-perovskite photo-assisted supercapacitor retained 93.8 % of its initial capacitance, after 10,000 charge-discharge cycles.

Novel Hybrid Floating Breakwater- Wave Energy Converter Device: Preliminary Experimental Investigations

The marine space is increasingly gaining ground as the ideal candidate to drive the energy economic sector as it hosts a huge amount of natural resources to be exploited, such as waves, wind, and solar irradiation. Innovative devices harnessing these marine renewable resources have been thought to be assembled in a new concept of an energy hub for the Mediterranean Sea, recently proposed by the National Research Council of Italy.&#x0D; The feasibility of this floating energy archipelago is strongly dependent on the creation of a protected sea area with reduced wave heights, where to safely install new types of floating devices for energy harvesting from the sea, like solar islands.&#x0D; For this purpose, a floating breakwater module has been specifically designed to surround the archipelago with one or more rows. Moreover, investigating the possibility to implement a dual and alternative use of this floating module, as a traditional dissipative system and wave energy converter has resulted in an extremely challenging task. With respect to the existing hybrid floating breakwater-Wave Energy Converters in fact, the novelty of this device is the optimization of both functionalities by varying its draft.&#x0D; In extremely rough seas, the hybrid module should only serve as a passive breakwater, soaking up incoming waves and safeguarding the equipment installed inside the archipelago. Otherwise, the floating module should operate as a WEC in more frequent mild sea states, assisting the archipelago's energy output. The whole produced energy can be stored and used to supply the development of new productive activities, such as aquaculture, the expensive process of seawater desalination, as well as the production of low environmental impact fuels like methanol or hydrogen.&#x0D; The model's dual functionality is accomplished by different draft values. This parameter is directly influenced by the volume of water pumped into the module, which raises the floater's displacement. The module is almost completely immersed in the first scenario, which simulates breakwater functioning, increasing the device's stability and the amount of reflected and dissipated waves. On the other hand, when the module exhibits WEC behavior, a lower displacement is necessary, allowing greater device motions, able to better exploit the energy of the waves.&#x0D; In this study, preliminary results obtained from an experimental campaign carried out on a 1:10 Froude-scaled model are reported. In particular, the dynamic behaviour of the hybrid device is evaluated in terms of response amplitude operators, while the attenuation performances are condensed in the transmission coefficient which indicates the reduction of the wave height inside the archipelago.
