본 발명은 종래의 이러한 문제점을 시정하기 위하여, 압력센서를 구성함에 있어서 전기적 부도체인 얇은 필름면에 탄소분말과 텅스텐(Tungsten) 산화분말 및 합성수지 접합체를 적량 혼합하여서 된 패스트상의 압력센서 소재를 소정의 일정한 두께로 적증하여 감압소자를 형성하였다. 이에 상대되는 전기회로는 전기적 부도체인 얇은 필름면에 전도성 고분자를 격자상으로 적층하여 전극판을 구성하였다.In order to correct this problem in the related art, in the construction of a pressure sensor, a pressure sensor material of a fast phase formed by mixing an appropriate amount of carbon powder, tungsten oxide powder, and a synthetic resin assembly on a thin film surface, which is an electrical insulator, is prescribed. It was evaporated to a constant thickness to form a pressure reducing element. In the electrical circuit, a conductive polymer was laminated on a thin film surface, which is an electrical insulator, to form an electrode plate.
상기 압력소자와 전극판을 대항하여 일조로 하고 상기 감압소자와를 누르면 격자상으로 격리된 두 전극은 통전이 되는 동시 두 전극간의 저항값은 압력에 따라 변화되므로 압력 센서의 기능을 가지는 것을 특징으로하며 압력에 대한 저항값의 변화폭이 비교적 넓어서 각종 전자기구의 압력센서로 사용할 수 있고 악기의 건반 등에 사용할 수 있고 다이얼, 컴퓨터의 기판 등의 정보입력 센서로 사용할 수 있다.When the pressure element and the electrode plate is formed as a pair and the pressure-reducing element is pressed, the two electrodes separated in a lattice form have a function of a pressure sensor since resistance values between two electrodes which are energized at the same time change with pressure. It can be used as a pressure sensor of various electronic devices, and can be used as a keyboard for musical instruments, and as an information input sensor for dials and computer boards.
실시예Example
도 1 및 도 2는 본 발명의 실시예를 나타낸 사시도 및 단면도이다. 즉, 본 발명에서는 탄소분말 40중량%, 텅스텐 30중량%, 합성수지 바인더 30중량%를 균질로 혼합하여 감압소재(1)를 조성한다. 전기적으로 부도체인 얇은 필름(2)의 한 면에 상기한 감압소재(1)를 10μ의 두께의 평면으로 도포하여 압력소자(3)를 구성한다. 상기 소자(3)와 대향하여 사용되는 전극판은, 부도체인 필름(4)의 한쪽면에 고분자 전도막으로 빗살모양의 대향된 전극(5)(5')을 서로 격리되게 적층형성하여 전극(5)(5')의 단부에 도선(6)(6')을 연결한다.1 and 2 are a perspective view and a cross-sectional view showing an embodiment of the present invention. That is, in the present invention, 40% by weight of carbon powder, 30% by weight of tungsten, and 30% by weight of synthetic resin binder are homogeneously mixed to form a pressure-sensitive material (1). The pressure element 3 is constituted by applying the above-mentioned pressure-sensitive material 1 on a plane of 10 mu m thickness on one side of the electrically non-conductive thin film 2. The electrode plate used to face the element 3 is formed by stacking opposite electrodes 5 and 5 'in the shape of a comb-shape with a polymer conductive film on one side of the film 4, which is a non-conductor, so as to be separated from each other. 5) Connect the conductors 6 and 6 'to the ends of 5'.
본 발명의 압력소자(3)와 전극판(5)(5')을 맞대어 압력센서로 사용하는바 누르는 기본 압력은 20g/cm2정도이고 임피던스 값은 10~30Ω 정도로 압력이 클수록 임피던스 값은 작아지고 압력이 작을수록 임피던스 값은 높게 된다. 따라서, 예컨대 전자악기의 건반으로 사용하면 건반을 누르는 압력에 따라 임피던스 값이 변하게 됨으로 건반을 강하게 누르면 음향이 크게 울리고 건반을 약하게 누르면 음향이 약하게 울린다. 본 발명은 구조가 간단하고 기능의 정도가 예민하며 안전성이 높기 때문에 각종 전자악기의 감압저항 가변성의 건반을 비롯하여, 압전 소자나 스트레인 게이지등으로 사용할 수 있고 측정변화값을 넓은 폭으로 다를 수 있다.When the pressure element 3 and the electrode plate 5, 5 'of the present invention are used as a pressure sensor, the pressing pressure is about 20 g / cm 2 and the impedance value is about 10-30 Ω. The lower the pressure, the higher the impedance value. Thus, when used as a key of an electronic instrument, for example, the impedance value is changed according to the pressure of pressing the key, so that when the key is pressed strongly, the sound is loud and when the key is weak, the sound is weak. The present invention can be used as a piezoelectric element, strain gauge, etc. as well as a variable pressure sensitive variable keyboard of various electronic instruments because the structure is simple, the degree of function is sensitive and the safety is high, and the measurement change value can be widely varied.
효과effect
본 발명은 상기한 바와 같이 구조가 간단하고 안전성이 높으며 압력에 따른 임피던스의 변화폭이 크기 때문에 각종 전자기구의 정보입력 키판, 전자압력 게이지, 전자악기 등의 감압센서로 유용하게 사용할 수 있는 효과가 있다.As described above, the present invention has a simple structure, high safety, and large change in impedance according to pressure, so that the present invention can be usefully used as a pressure-sensitive sensor for information input keypads, electronic pressure gauges, electronic instruments, etc. of various electronic devices. .
