The heart’s motion is so powerful that it can recharge lifesaving cardiac devices, according to new research from Dartmouth College.

Engineers at Dartmouth’s Thayer School of Engineering developed a dime-sized device to convert the heart’s kinetic energy into electricity to power a wide range of implantable devices, according to the Hanover, N.H.-based college.
