Abstract
A pressure sensor and a pressure measuring device are provided applicable to a variety of pressure detection targets and capable of measuring a surface pressure. The pressure sensor is configured by laminating a metal layer made of a metal film, an elastic member layer made of a non-metal material, and a coil layer including an exciting coil. Also, as for a sensor sheet on which sensors that each measure point pressure are arranged in an array, variable elements of the elastic member layer and the coil layer are appropriately changed, thereby forming sensors with a single sheet that are different in pressure detection accuracy or pressure detection range for predetermined areas. Also provided is a pressure measuring device that controls exciting timing or frequency of applied voltage of each exciting coil on a sensor sheet.
