Abstract

This paper presents an elastic ribbon-like piezoelectric energy harvester which is targeted for skin-wearable devices by harnessing the movements of stretchable surfaces. The device aims to power up smart thin stick-on devices for healthcare monitoring. By embedding a ribbon-like PVDF film in a flexible elastomer, Ecoflex, the device is potentially able to stretch 34%, while maintaining internal strain of the film below its plastic deformation limit. Alternate electrode layout and bimorph configuration help to reduce charge cancellation, while increasing overall effectiveness. The harvester prototype with 225 mm3 active volume is able to output 15.6 V at open-circuit upon stretching 26% and is capable of generating at least 121 nJ per cycle.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
