Abstract: The invention provides a sensor capable of detecting deformation. The deformation sensor has a structure in which an ion-conductive polymer layer is sandwiched between soft electrodes, wherein non-uniform ion distribution is generated in the ion-conductive polymer layer by deformation, thereby generating a potential difference between the electrodes.
