본 고안은 감압저항 가변형 압력센서에 있어서, 얇은 필름의 대지에 공지한 고분자 도전체막을 적층 형성하고, 이 대판과 대향한 또다른 필름의 대지에는 빗살모양으로 음전극과 양전극을 교호로 배치하고 그 표면에 탄소분말과 텅스텐(TUNGSTEN)산화분말로 된 감압저항 가변형 센서소자를 적층 형성하여 상기한 고분자 도전체막과 맞대어 누르면 압력에 대한 저항변화를 감지하여 전기적 신호로 전달할 수 있게 한 감압저항 가변형 압력센서에 관한 것이다.The present invention is a pressure-sensitive resistance variable pressure sensor, in which a well-known polymer conductor film is laminated on a thin film site, and another negative electrode and a positive electrode are alternately arranged on the surface of another film facing the base plate, and the surface thereof is alternately arranged. The pressure-sensitive resistance variable pressure sensor formed by stacking carbon powder and tungsten (TUNGSTEN) oxidized powder on top of each other and pressed against the polymer conductor film to detect a change in resistance to pressure and transmit it as an electrical signal. It is about.

종래의 감압저항 가변형 센서는 압전소자, 스트레인게이지 등에 사용하고 있으나 감압소자를 사용하였기 때문에 복원력이 빠르고 변화에 민감하며 그 변화량이 미소하여 복잡한 보조회로가 부가되어야만 사용할 수 있고, 값이 비싸며 용도에 제한받는 문제점이 있었다.Conventional pressure-sensitive resistance variable type sensor is used in piezoelectric element, strain gauge, etc., but because it uses the pressure-reducing element, the restoring force is fast and sensitive to change, and the amount of change is small so that it can be used only when a complicated auxiliary circuit is added. There was a problem.

본 고안은 종래의 이러한 문제점을 시정하기 위하여 한쪽 필름의 대지에 고분자 도전체막을 적층 형성하고, 다른쪽 필름의 대지에는 고분자 도전체의 매트릭스를 적층 형성한 다음, 그 표면에 감압 저항 가변형 센서소자를 적층 형성하여 감압센서를 구성함으로써 구조가 간단하고 예민하게 반응하지 않아 안전성이 높고 임피던스의 변화범위가 넓기 때문에 종래와 같은 보조회로의 부가없이 간단한 접속회로를 구성하여 각종 전자기구에 유용하게 사용할 수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in order to correct this problem of the prior art, a polymer conductor film is laminated on the ground of one film, and a matrix of the polymer conductor is laminated on the ground of the other film, and then a pressure-sensitive resistance variable sensor element is formed on the surface. Since the structure is simple and does not react sensitively by forming a stacked pressure sensor, the safety is high and the range of impedance change is wide. Therefore, a simple connection circuit can be usefully used for various electronic devices without adding auxiliary circuits as in the prior art. It will be described in detail by the drawing as follows.

한쪽의 부도체 필름의 대지(1)에는 고분자 도전체막(2)을 적층 형성하고 다른쪽의 부도체 필름의 대지(1')에는 고분자 도전체막을 매트릭스 전극(2')을 형성하고, 그 상면에 탄소분말과 텅스텐산화분말을 합성수지 접합제로 혼합적층한 감압저항 가변형 압력센서소자(3)를 적층 형성하여 압력센서를 구성하여서 된 것이다.The polymer conductor film 2 is laminated on the substrate 1 of one non-conductor film, and the polymer electrode film is formed on the substrate 1 'of the other non-conductor film, and a matrix electrode 2' is formed on the upper surface thereof. The pressure sensor was constructed by laminating a pressure-sensitive resistance variable pressure sensor element 3 in which a powder and tungsten oxide powder were mixed with a synthetic resin binder.

또 본 고안의 실시에 있어서, 제3도에 표시한 바와 같이 고분자 도전체 매트릭스전극(2')이 형성된 한쪽 대지(1')와 다른쪽 대지(1)에 탄소분말과 텅스텐산화분말을 합성수지 접합제로 혼합 적층한 감압저항 가변형 압력센서(3)(3')를 적층 형성할 수도 있다.In the practice of the present invention, as shown in FIG. 3, carbon powder and tungsten oxide powder are bonded to one earth 1 'and the other earth 1 on which the polymer conductor matrix electrode 2' is formed. It is also possible to form a pressure-sensitive resistance variable pressure sensor 3 (3 ') that is a mixture of zero and laminated.

이와 같이 된 본 고안은 압력센서, 스트레인게이지 기타 각종 전자기구의 스위치 접점 등에 사용하는 것으로, 한쪽 대지(1)에는 고분자 전도체막(2)이나 감압저항 가변형 센서소자(3')를 적층하고 다른쪽 대지(1')에는 고분자 도전체막으로 된 매트릭스 전극(2')을 형성한 다음, 그 위에 감압저항 가변형 센서소자(3)를 적층 형성하였기 때문에 두 전극에 도선을 연결하고 상하의 대지(1)(1')를 가압하면 압력조건에 따라 전도체막(2)과 감압저항 가변형 센서소자(3)(3')를 통한 저항값이 다르게 나타나게 되어 압력변화를 감지하거나 전자오르겐의 건반을 누르는 압력에 따라 소리의 강도를 다르게 나타낼 수 있는 등 다양한 용도로 사용할 수 있고, 구조가 간단하여 임피던스의 범위가 넓어서 별도의 보조회로를 추가하지 않고도 사용할 수 있으며, 값이 비교적 경제적으로 저렴하여 종래의 것에 비하여 보다 편리하게 사용할 수 있는 효과가 있다.The present invention is used for switch contacts of pressure sensors, strain gauges, and other electronic devices, and the like (1) is laminated with a polymer conductor film (2) or a variable pressure resistance variable sensor element (3 ') on one side (1). On the ground 1 ', a matrix electrode 2' made of a polymer conductor film was formed, and then a pressure-sensitive resistance variable sensor element 3 was laminated thereon. Therefore, conducting wires were connected to both electrodes, and the upper and lower ground 1 ( 1 '), the resistance values through the conductor membrane 2 and the pressure-sensitive resistance variable sensor element 3 (3') appear differently depending on the pressure conditions, so as to sense the pressure change or to press the key of the electron orgen. It can be used for various purposes such as different sound intensity can be displayed, and its structure is simple, so the impedance range is wide, so it can be used without adding an auxiliary circuit. Inexpensive expelled by the effect that can be more conveniently used as compared to the prior art.
