This letter reports on a dual-mode wearable energy harvester that utilizes both piezoelectric and photoelectric effects. It integrates a piezoelectric transducer with a 3-D photosensitive dual-gate thin-film transistor (DGTFT) as a rectifier and a buffer. The energy conversion efficiency is enhanced by reducing the internal resistance of the 3-D photosensitive DGTFT upon light illumination. Such a dual-mode energy harvester is promising for wearable electronics.
