Small, sustainable power sources will be necessary to power the network of sensors used in smart homes and autonomous vehicles, and for environmental monitoring. Energy harvesters scavenging energy from the environment are ideal, but their output so far has been too low for driving sensor electronics. Researchers have worked to make devices that harvest energy from multiple sources to boost power output. A new leaf-like energy generator converts the energy from falling raindrops and blowing wind into electricity, generating enough power to light up 10 LEDs, at least for short bursts of time.

Very cool!
