Zusammenfassung: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.
