Abstract

This work presents a biodegradable triboelectric nanogenerator (BI-TENG) made from biodegradable materials to collect mechanical energy *in vivo* and convert it into electricity for implantable medical devices. Reed film and polylactic acid (PLA) were selected as triboelectric layers, achieving 368 V. Biocompatibility was confirmed, and *in vivo* testing in mice showed 0.176 V and 192 nA output from body movement. The BI-TENG stimulated accelerated doxorubicin (DOX) release from red blood cells for targeted drug delivery, demonstrating potential in cancer treatment.
