A flexible spring-shaped architecture with optimized thermal design for wearable thermoelectric energy harvesting

Recent Advances in Materials for Wearable Thermoelectric Generators and Biosensing Devices

“…The clinical trials of TEG-based health monitoring systems will further the real-time progress of TEGs, hence relaxing the efforts for commercializing this smart technology. Though recent studies successfully increased the efficiency of TEGs from 5% to 20% in high-temperature applications, for WTEGs, this efficiency has yet to be achieved [13,37,[49][50][51][52]. The applicability of a self-powered health monitoring system needs the development of new materials, especially the n-type thermoelectric (TE) material, to increase the power output from WTEGs with the advent of flexible energy storage units and multipowered systems [53,54].…”

Integrating recyclable polymers into thermoelectric devices for green electronics

“…In recent years, with the rapid progress of flexible electronics, flexible TEGs have become ever more crucial to providing an energy source for these flexible devices. 25–35…”

Biomechanical Regenerative Braking Energy Harvester: A Systematic Analysis

“…First, the method of harvesting energy through body temperature mainly involves attaching a thermoelectric or pyroelectric generator to the skin to convert the heat of the human body into electricity [ 4 ]. An electrical power density of 0.45–18 μW/cm 2 can be harvested through this method [ 5 – 7 ]. Another harvesting method uses kinetic energy from the human body.…”
