Flexible and stretchable chain battery

Abstract:

A flexible and stretchable chain battery includes multiple individual batteries connected in parallel and/or in series via stretchable conductive interconnects. The positive terminals of each battery are connected to a first stretchable conductive interconnect and the negative terminals of each battery are connected to a second stretchable conductive interconnect. The stretchable conductive interconnects and the batteries are coupled to a stretchable substrate. The stretchable conductive interconnects provide electrical interconnection between the multiple batteries while enabling stretchability between the batteries.
