Recently, Zhang Min's research group published a research paper titled "A Mechanically Tunable Electromagnetic Wave Harvester and Dual-modal Detector based on Quasi-static van der Waals Heterojunction" in Nano Energy journal. (DOI: 10.1016 / j. anoen. 2022.107399). In this study, a mechanically adjustable electromagnetic energy collecting device was proposed and realized by applying pressure to van der Waals contact heterojunction. It provides a new perspective for the study of energy conversion mechanism of friction volt DC generator based on van der Waals contact heterojunction.
