Harvesting energy from ambient environment has become a promising solution to solve the energy problem of microsystems. To further increase the energy conversion efficiency or expand the application scenes of energy harvesters, hybrid energy harvesting technology based on the Triboelectric nanogenerators (TENG) has been developed.
Self-charging power unit and self-sustainable power source using TENG is meaningful for portable electronics. There are many urgent issues to be resolved for TENG's practical applications in real life. Among which, the power management and effective energy storage connect TENG and its energy supply equipment which is of great significance are investigated.
TNEG based self-powered electronic skins (e-skins) have been developed with rational design to accomplish multifunctions of sensing including the pressure, position, strain, sliding and so on. It is expected that the self-powered e-skin will continue its fast development and make more progress to make the e-skin come into human life in the near future.
Portable and wearable self-powered systems have made significant progress and may become the main form of the next generation of electronic devices. The rapid development of materials science, processing technology, and smart technology will pave the way for wearable self-powered systems in practical applications.
Wearable biosensors hold the potential of revolutionizing personalized healthcare and telemedicine. Advances in chemical sensing, flexible materials, and scalable manufacturing techniques now allow wearables to detect key physiological indicators such as temperature, vital signs, body motion, and molecular biomarkers.
