Piezo-based energy harvesting within medical implants

medical-piezoheart0(Bill Schweber / EENews) – Researchers developed a prototype energy-harvesting transducer for medical implants, such as pacemakers, using normal motion of the heart-related blood vessels to generate critical power.

    Energy harvesting from the human body (approximately 100W of consumption at rest) in various forms appears to be a near-perfect power source fit for implanted medical devices, but practical issues have impeded its adoption as a solution.

Funded by a five-year NIH Director’s Transformative Research Award, a research team at the Thayer School of Engineering at Dartmouth College worked with UT Health San Antonio (part of the University of Texas) and developed a new way to build a piezo-based harvesting transducer for these medical devices.
