Implant Powered by a Beating Heart

Implant Powered by a Beating Heart
A dime-sized device able to capture the energy of a beating heart could power future implants.

One of the primary challenges of creating biomedical implants is the need to power them. Rising to this challenge, the team from Dartmouth University modified standard pacemakers to harvest the kinetic energy of the heart. The design relies on a thin, porous piezoelectric film attached to the pacemaker’s lead that converts motion to electricity and powers the implant. According to the team, the technology could also be used to power other implanted biomedical devices.
