When an external pressure is applied, the place to which the pressure application is performed can be specified from the ratio of response voltage of the pressure response means 9a and 9b since the ratio is differed for each place coordinate.

摘要： PROBLEM TO BE SOLVED: To solve the problem in conventional flexible pressure-sensitive elements, wherein it may pick up as noise, pressure or signals in directions other than a direction in which detection is to be made, since it has isotropic sensitivity with respect to external pressure, and wherein signal processing for removing of the noise becomes complicated. SOLUTION: This cable-like flexible pressure-sensitive element comprises a protective layer 13, a core electrode 14, an outer electrode 12, and a flexible pressure-sensitive body 11. In this element, by giving anisotropy to the spontaneous polarization Pp of a cross section vertical to the longitudinal direction of a cable in Fig. 1(b), the anisotropic spontaneous polarization Pp causes selective electric charges to be generated in a pressure-sensitive direction F and a voltage, corresponding thereto, to be generated. As a result, pressure/vibration, applied in the pressure-sensitive direction, can be detected with low noise, realizing superior sensitivity. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the following problem that the sensitivity of pressure detection of a conventional flexible pressure-sensitive element is low, since the strain of a flexible pressure-sensitive body 11 due to pressure from outside is small and generated voltage is low. SOLUTION: By making the constitution of this pressure-sensitive element have a static-load applying portion 16 in addition to a protective layer 13, a core electrode 14, an outside electrode 12, and a flexible pressure-sensitive body 11, a static load Ps is applied to the pressure-sensitive body 11 via the protective layer 13 and the outside electrode 12 from the static-load applying portion 16.
