Mechanically Powered Transparent Flexible Charge‐Generating Nanodevices with Piezoelectric ZnO Nanorods

Transparent flexible charge-generating piezoelectric nanodevices are developed. The resulting integrated nanodevice generates a noticeable current when it is pushed by application of an external load. Piezoelectric ZnO nanorod-based nanodevices with embossed PdAu top electrodes produce the highest output current density of approximately 10 μA cm−2 at a load of 0.9 kgf.
