Polymer-based sensor apparatus and method

摘要

A strain sensor ( 10 ) includes a flexible substrate ( 11 ) having one or more polymer-based resistive elements ( 12 ) at least partially conformably disposed thereon. Two or more conductive leads ( 13, 14 ) 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.
