Impact of Diverse Ambient Illuminations on a Flexible Photosensitive Energy Scavenger

Abstract

This paper details the effect of diverse environmental light conditions on characterization of a piezoelectric transducer biased photosensitive dual-gate thin-film transistor as a dual-mode wearable harvester. It demonstrates that exposure of harvesting module over ambient illuminations effectively decreases the internal resistance of DGTFT and results in peak voltage enhancement along with peak power increment. Ultimately an in-depth experimental analysis of peak power under distinct ambient illuminations shapes a daily usage pattern for further investigation.
