Super-Flexible Nanogenerator for Energy Harvesting from Gentle Wind and as an Active Deformation Sensor
نویسندگان
چکیده
Using an Al-foil of thickness ≈ 18 μ m as a substrate and electrode, a piezoelectric nanogenerator (NG) that is super-fl exible in responding to the wavy motion of a very light wind is fabricated using ZnO nanowire arrays. The NG is used to harvest the energy from a waving fl ag, demonstrating its high fl exibility and excellent conformability to be integrated into fabric. The NG is applied to detect the wrinkling of a human face, showing its capability to serve as an active deformation sensor that needs no extra power supply. This strategy may provide a highly promising platform as energy harvesting devices and self-powered sensors for practical use wherever movement is available.

Harvesting unexploited energy in the living environment to power small electronic devices and systems is attracting increasing massive attention. [ 1–7 ] As the size of the devices has shrunk to the nanoor microscale, the power consumption also decreased to a modest level, i.e., the microwatts to milliwatts range. It is entirely possible to drive such a device by directly scavenging energy from...
