US Patent 10401241 Surface sensor arrays using ionically conducting material

Sensor arrays are provided for sensing pressure and/or moisture over a two-dimensional sensing surface. The sensor arrays comprise ionically conductive materials. Individual sensor elements in the sensor arrays may comprise piezoionic ionically conductive materials, piezoresistive ionically conductive materials and/or capacitive sensor elements having electrodes fabricated from ionically conductive materials. Two-dimensional pressure maps and/or moisture maps of the sensing surface may be obtained by implementing methods comprising scanning over individual sensor elements in the sensor arrays.
