  • Patent number: 9423309
    Abstract: A pressure sensor comprising: a base film on which a conductor pattern having one or more electrodes is formed; a cover film laminated on the base film so as to cover the electrodes of the conductor pattern; and a spacer disposed between the cover film and the base film so as to form a hollow portion having a predetermined gap between the electrode and the cover film; wherein a portion corresponding to the hollow portion of the cover film is constructed such that it has a pressure sensing part which is able to deform in a direction to move toward and away from the electrode in accordance with pressure, and of which contact resistance changes in accordance with a contact pressure thereof with the electrode, so that the pressure sensing part detects the pressure by a change of the contact resistance.

  • Patent number: 7973274
    Abstract: The invention provides a tactile sensor module that enables adjustment of the density of sensing elements and adjustment of mounting regions to be carried out in a straightforward manner with one type of module that is highly adaptive to complex curved surfaces. A tactile sensor module comprises a flexible substrate having one or a plurality of strips, a plurality of sensing elements arranged at the one or plurality of strips of the flexible substrate, one or more communication terminals provided at the flexible substrate; and at least one electronic circuit section provided at the flexible substrate having communication functions. At least one of the strips comprises a foldable region and/or a cuttable region.
