Energy harvesting: materials, structures and methods

With the advent of technology miniaturization, portable electronic devices are evolving at a rapid pace, especially in field wireless sensor networks for IoT applications. On contrary, battery has not seen similar growth miniaturization. Also, frequent replacement batteries is challenging located remote places. Energy harvesting from ambient conditions may be one solution to above challenges. The and powering becoming increasingly popular among researchers working on structural health monitoring systems. Thermoelectric, piezoelectric, electromagnetic, electrostatic triboelectric mechanisms major energy transduction methods adopted development devices. Many these have limitations including relatively low power density, narrow bandwidth efficiency lower frequencies. virtual International Conference Advances Harvesting Technology (ICAEHT 2021, 18–20 March 2021) was organized bring together discuss possible solutions future directions. content this special issue inspired contributions discussions made during ICAEHT 2021 few more invited papers. 19 selected papers cover thermoelectric, electromagnetic harvesters. Modelling, analysis, optimization, control, experimentation, management application aspects harvesters covered entitled “Energy harvesting: materials, structures methods”. We hope that readers will find quite interesting, encouraging novel.
