Scientists invent biodegradable battery that controls the beating of hearts

The tiny battery features capabilities useful for biomedical applications, including powering drug molecule release and heart defibrillation - (Yujia Zhang)

Scientists have invented a new type of biodegradable battery that could revolutionise robotics and transform the field of biomedical devices.

It is the first ever lithium-ion battery – the same type of battery found in everything from smartphones to solar energy storage systems – that is simultaneously high capacity, biodegradable, and capable of controlling remotely.
