Scientists have used a compound made from a starch derivative and baking soda to help convert mechanical energy to electrical energy. The approach, developed by scientists at Daegu Gyeongbuk Institute of Technology (DGIST), with colleagues in Korea and India, is cost-effective and biocompatible, and can help charge low-energy electronics like calculators and watches. The details were published in the journal Advanced Functional Materials.
