Researchers have used waste pomelo-peel biomass to power small electric devices and monitor biomechanical motions. The method was developed by researchers at the University of Illinois Urbana ...

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

Pomelo peel was used to create devices that can convert mechanical energy into electricity and serve as self-powered motion sensors.
