Device Harvests Energy From Moving Organs To Power Implants



by Michael Keller

Your heart expends half a joule of energy every time it beats. That’s the same amount of juice you’d need to lift an apple 1.6 feet off the ground.

Before every contraction, the potential energy trapped in chemical bonds within cardiac muscle cells is released and converted into the mechanical power of the heartbeat. But, like all energy, that which is harnessed to power the heart is never destroyed; it just changes form as it radiates away from the organ as heat and vibrations of surrounding tissue and fluid. 

Now, a science team has announced a breakthrough in harvesting the energy released from the movement of the beating heart, the breathing lung and the flexing diaphragm. They’ve developed a superthin device that can be attached to an organ to generate electricity from its movements.
