Flexible organic batteries could fit pacemakers

A new kind of flexible “organic battery” could provide a more comfortable alternative to people fitted with pacemakers, say researchers.

Currently, heart devices such as pacemakers and defibrillators are powered by rigid metal-based batteries implanted under the skin that can rub and cause soreness.

The new invention from Queen’s University, Belfast, is made from biodegradable organic material and can change shape to suit the user.
