Abstract
A strain sensor () includes a flexible substrate () having one or more polymer-based resistive elements () at least partially conformably disposed thereon. Two or more conductive leads () are electrically coupled to the resistive element. Flexure of the resistive element causes a corresponding alteration in a measurable electrical property of the resistive element, such as its characteristic impedance. User interfaces of various kinds can be fabricated with such strain sensors.
