Enhanced Energy Harvesting Performance of Biodegradable Polylactic Acid/3D Anodic Aluminum Oxide Composite Triboelectric Nanogenerators

open access: yesAdvanced Electronic Materials, EarlyView.
Polylactic acid (PLA) embedded in 3D anodic aluminum oxide (3D‐AAO) yields triboelectric nanogenerators (TENGs) with ɛeff = 5.1, delivering 20V and 108µW both per cm2. These agglomeration‐resistant, compostable/biocompatible devices retain 95% output after 104 cycles, enabling robust self‐powered Internet of Things (IoT) sensing.
