Vitamins are good for your multi-energy nanogenerator

Researchers report a simple, innovative and inexpensive design of a vitamin-based hybrid biocompatible nanogenerator with energy harvesting ability from various energy sources in a single device. This is the first time that inexpensive and biocompatible vitamin B2 has been used as a novel and effective beta-phase stabilizer to enhance the piezoelectric performance of PVDF. The attractiveness of using vitamin B2 is that it is biodegradable and biocompatible, thermodynamically stable, low-cost, has delocalized pi-electrons, contains multiple numbers of hydroxyl groups, carbonyl groups and amino groups in its backbone.
