Heart-Beat Scavenger (HBS) Consortium, a French based Medical Electronics reaserch group is targeting an energy self-sufficient device that harvests mechanical energy from the movements of the heart, eliminating the need for batteries and post-implant surgeries to replace them. A longer-term goal of the project is to reduce healthcare expenditures. Heart failure represents one of the biggest public-health costs today in Europe and the United States.

Heart-Beat Monitor & Cardiac Pacemaker - Heart-care ElectronicsTechnological advances in miniaturizing and cutting the power consumption of electronic components, as well as the advent of energy-harvesting devices, have opened the way to new self-powered implants that significantly improve patient comfort and lower cost, particularly by reducing the number of post-implant surgeries required. These devices constitute a new market for active implantable medical devices (AIMDs) for treating or diagnosing heart diseases.

Heart-Beat Scavenger (HBS) Consortium is built by CEA-Leti with five partners: Sorin Group, TIMA, Cedrat Technologies, Tronics and EASII IC. The goals of Heart-Beat Scavenger (HBS) Consortium are:

  • Developing a self-powering pacemaker by harvesting the mechanical energy produced by the movements of the heart and eliminating the need for batteries that must be replaced every six to 10 years.
  • Reducing the size of a cardiac pacemaker by a factor of eight, from 8 cm3 to 1 cm3. This reduction will make it possible to attach the pacemaker directly to the epicardium, eliminating the need for intravenous introduction of cardiac probes.

CEA-Leti is responsible for the mechanical energy-harvesting unit for the prototype, and for designing and creating its capacitance-conversion system. The Sorin Group is positioning itself in the AIMDs market in Europe and globally and hopes to create jobs in the Grenoble region.
