Wearable and Stretchable Piezoelectric Nanogenerator for Skin Applications

The paper describes a stretchable piezoelectric nanogenerator that is intended to harvest energy. The nanogenerator was fabricated from zinc oxide (ZnO) piezoelectric thin film embedded in polymer materials. The microfabricated nanogenerator has the thickness in the micrometer scale to be attached on the skin and stretched by the natural movements of arms, legs or neck. We expect that energy harvested by this device will be able to power wearable skin sensors.
