Abstract
A stretchable flexible pressure sensor includes stretchable conductive interconnects, or electrodes, sandwiching an elastic substrate that is stretchable in one or more directions. The interconnects are positioned on opposing surfaces of the elastic substrate and overlap at select sensing areas. The elastic substrate at each sensing area is replaced with a foam or air gap to enable movement of a top stretchable conductive interconnect, a bottom stretchable conductive interconnect or both toward each other in response to an applied force. The stretchable conductive interconnects are each patterned having a meandering shape and are aligned with each other. The meandering shape provides slack such that as the elastic substrate is stretched the slack is taken up.
