Challenges and Prospects of Energy Harvesting in Medical Implants - Focus on Cardiac Implants
Advances in electronics and in physical and biological sensors over the last twenty years have led to remarkable progress in the field of active medical implants. However, the miniaturization of implants remains highly dependent on energy requirements, with batteries often occupying a large part of the available volume. One way to push the limits in terms of autonomy and miniaturization would be to take advantage of the biomechanical energy of the human body, in order to locally generate the necessary electrical energy.
In this presentation, the mechanical energy available in the heart will be more particularly examined and piezoelectric and electrostatic energy harvesting devices, some of which are about to be clinically tested, will be presented. Finally, we will look at the possibilities offered by recent advances in nanomaterials.
