Abstract
A sensor comprises conductive elements arranged and connected for proximity sensing. The conductive elements are formed of an ionically conductive polymer. The sensor may also include conductive elements arranged and connected for touch sensing. The conductive elements may be connected to an alternating-current (AC) source. Another sensor comprises one or more conductive elements arranged and connected for touch sensing by detecting resistivity changes in the one or more conductive elements. A flexible and transparent sensor is also provided, which comprises a layer of a piezoelectric polymer and conductive elements in contact with the layer for transmitting an electric signal generated by compression of the layer. Methods and processes for using such sensors are also provided.
