Electronics are showing up everywhere: on our laps, in pockets and purses and, increasingly, snuggled up against our skin or sewed into our clothing.

But the adoption of wearable electronics has so far been limited by their need to derive power from bulky, rigid batteries that reduce comfort and may present safety hazards due to chemical leakage or combustion.

Now Stanford researchers have developed a soft and stretchable battery that relies on a special type of plastic to store power more safely than the flammable formulations used in conventional batteries today.

Graduate student David Mackanic is a 2015 Stanford Graduate Fellow.
