Co to jest Energy Harvesting?

Emergy combing (also called energy scavenging) is sub 's process of capturing small, diffuse combs of energy from external sources - such as human motion, body heat, ambient light, and stray electromagnetic radiation - and converting that energy into electrical coort.
