Abstract
In the last few decades, technology innovation has had a huge influence on our lives and well-being. Various factors of observing our physiological characteristics are taken into account. Wearable sensing tools are one of the most imperative sectors that are now trending and are expected to grow significantly in the coming days. Externally utilized tools connected to any human to assess physiological characteristics of interest are known as wearable sensors. Wearable sensors range in size from tiny to large tools that are physically affixed to the user and operate on wired or wireless terms. With increasing technological capabilities and a greater grasp of current research procedures, the usage of wearable sensors has a brighter future. In this review paper, the recent developments of two important types of wearable electronics apparatuses have been discussed for temperature and pressure sensing (Psensing) applications. Temperature sensing (Tsensing) is one of the most important physiological factors for determining human body temperature, with a focus on patients with long-term chronic conditions, normally healthy, unconscious, and injured patients receiving surgical treatment, as well as the health of medical personnel. Flexile Psensing devices are classified into three categories established on their transduction mechanisms: piezoresistive, capacitive, and piezoelectric. Many efforts have been made to enhance the characteristics of the flexible Psensing devices established on these mechanisms.
Highlights
Pure metal elements (Pt, Au, Cu) [76,77,78], metal oxide particles [79], carbon nanotube (CNT) polymer composites [80], and graphene [81] have all been used as sensitive materials in resistive Tsensing apparatuses
We have reviewed the recent developments in the field of flexible wearable electronics temperature and pressure sensors
Wearable Tsensing is appealing not just in the medical field, and for tracking and monitoring the body temperature of healthy people participating in vigorous outdoor activities
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. The most common method for making soft sensing apparatuses has been to use transfer printing [3], screen printing [4], photolithography [5], microchannel molding [6], and lamination [7] to combine deformable conducting material patterns onto a stretchy substrate These technologies, have some drawbacks, including high cost, multistep manufacturing processes, low durability, and prototyping and scaling issues. Novel gadgets are being developed to provide for the most comfortable continuous monitoring of vital signs By connecting these wearable medical electronic apparatuses to the human body surface, they can measure different health information, for instance, heart rate, pulse, body temperature, blood glucose, among others, noninvasively and in real-time [16,17,18,19].
