An Integrated Charge Excitation Alternative Current Dielectric Elastomer Generator for Joint Motion Energy Harvesting (Adv. Mater. Technol. 6/2024)

Joint Motion Energy Harvesting In article number 2301172, Zisheng Xu, Shiju E, and co‐workers describe a novel approach to harvest joint motion energy by a hierarchical charge‐boosting structure design (ACENG‐DEG). The ACENG‐DEG, utilizing ion hydrogel electrodes and an electret nanogenerator, exhibits remarkable stretchability and a high energy conversion efficient through a stretch‐based mechanism. With only 37 cycles, the device reaches a high voltage of 1.18 kV and generates an ultrahigh output charge of 1.9 μC per cycle.
