A pair of first electrodesis arranged in a state being separated in a direction parallel to a contact surfaceof a base materialmade of a dielectric and being at least partially in contact with the base material. A pair of second electrodesis arranged in a state of overlapping at least one of the pair of first electrodes and sandwiching the base materialat a position farther from the contact surfaceof the base materialthan the pair of first electrodesandin a direction perpendicular to the contact surfaceof the base material. The proximity state of an object Q with respect to the contact surfaceof the base materialis detected according to the measurement result of the capacitance Cbetween the pair of first electrodesand

Capacitance detection sensor, capacitance detection sensor module and state determination method using capacitance detection sensor

A method of sensing a pressure applied to a surface comprises monitoring an electrical signal generated by redistribution of mobile ions in a piezoionic layer under the surface. An externally applied local pressure at a portion of the layer induces redistribution of mobile ions in the piezoionic layer. It is determined that the surface is pressured based on detection of the electrical signal. A piezoionic sensor includes a sensing surface; a piezoionic layer disposed under the sensing surface such that an externally applied local pressure on a portion of the sensing surface causes detectable redistribution of mobile ions in the piezoionic layer; and electrodes in contact with the layer, configured to monitor electrical signal generated by the redistribution of mobile ions in the piezoionic layer.

Method and sensor for pressure sensing based on electrical signal generated by redistribution of mobile ions in piezoionic layer

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.
