The smallest implantable battery in the world may soon be powering bionic neurons. The small size allows doctors to use minimally invasive techniques when implanting the bionic neurons, reducing surgical trauma and the risk of infection.

Recharging is done wirelessly by an external electrical field, so implants no longer have to be surgically removed and replaced.

The battery may power implantables for stroke victims and people suffering from urinary-urge incontinence and neurological disorders such as Parkinson’s disease.
