  • Pressure detection unit and pressure detection device
    Patent number: 8635919
    Abstract: A pressure detection unit includes a first substrate and a second substrate which are disposed in opposition to each other and subject to load from the outside, a pair of electrodes provided in distribution in the first substrate and the second substrate, the electrodes being disposed linearly in opposition to each other, electrically conductive pressure-sensitive ink disposed between the pair of electrodes to cover at least one of these electrodes and having electrical characteristics which varies according to the load, and an adhesion member for adhering the first substrate and the second substrate to each other with the pair of electrodes and the pressure-sensitive ink being placed in contact with each other.
    Type: Grant
    Filed: August 26, 2010
    Date of Patent: January 28, 2014
    Assignee: Nissha Printing Co., Ltd.
