Waste to wealth: Pomelo peel can be used for electricity generation and sensing devices

Pomelo is a large citrus fruit commonly grown in Southeast and East Asia. It has a very thick peel, which is typically discarded, resulting in a considerable amount of food waste. In a new study published in ACS Applied Materials & Interfaces, University of Illinois Urbana-Champaign researchers explore ways to utilize waste pomelo-peel biomass to develop tools that can power small electric devices and monitor biomechanical motions.
