Nanowerk  April 18, 2022 Until now, studies on wireless energy transfer (WET) have been mainly based on the electromagnetic (EM) induction method using EM waves. However, it is still challenging to utilize current EM wave mediated WET in those areas where it is most needed: underwater, body-implant, and EM-shielded cases (liquid/metals). Researchers in South Korea have developed a triboelectric acoustic energy transfer (AET) module by tuning the work function of the triboelectric layer via the large polarization of the embedded relaxor single crystal. The uniform displacement, a quasi-mode oscillation, across the flexible electrode surface in response to the square wave […]
