Towards miniaturization of medical devices

Since the first implantation of an artificial pacemaker in 1960, physicians and surgeons have been developing more and more implantable autonomous devices to treat patients with serious health conditions. Examples of these medical devices are cochlear implants, pacemakers and defibrillators.

Because most of these implants require surgery once the battery is nearly empty, the use of a rechargeable battery would significantly reduce costs and lower risks for patients.

Nevertheless, in order to be implanted inside a human body, the batteries must be very small, without any flammable component like lithium or a liquid electrolyte, and last for many years.

The microbatteries developed by ITEN perfectly fit these criteria.
