  • Infrared detection element and infrared detection device
    Patent number: 10823620
    Abstract: An infrared detection element includes a pyroelectric body, first and second light receiving electrodes, and blackened films. The first light receiving electrode is provided on a surface of the pyroelectric body and receives infrared light from a first region. The second light receiving electrode is provided on a surface of the pyroelectric body and receives infrared light from a second region. The blackened films are provided on a surface of the first light receiving electrode and are not provided on a surface of the light second receiving electrode. Thus, infrared reception sensitivity is different between the first light receiving electrode and the second light receiving electrode.
    Type: Grant

  • Infrared detection circuit and infrared sensor
    Patent number: 10809130
    Abstract: An infrared detection circuit includes an infrared sensor element, detects infrared rays and outputs a detection signal to an external detection circuit. The infrared detection circuit includes an impedance element connected between a ground of the infrared sensor element and a ground of the external detection circuit and including at least one of resistivity and inductivity. The impedance element blocks noise from outside. The ground of the infrared sensor element is connected to the impedance element via a ground of an internal substrate of the infrared detection circuit.
