The researchers built a nanogenerator using a flexible, biocompatible polymer film made out of polyvinylidene fluoride, or PVDF. To improve the material's energy-harvesting ability, they added DNA, which has good electrical properties and is biocompatible and biodegradable. Their device was powered with gentle tapping, and it lit up 22 to 55 light-emitting diodes.
