Abstract

PURPOSE: An electric capacitor touch sensor is provided to change the necessary time for entering until the constant voltage while touching with a finger. CONSTITUTION: The finger of a person is one side of a capacitor. An insulator acts as other side of the capacitor. An insulating tape act as a dielectric. If the finger of the person reaches, the time needed for the capacity to reach to the constant voltage is changed. By measuring and using the time, the operation which a user desires is coded.

Description

정전용량을 이용한 터치 센서{ Electric capacitor touch sensor}Capacitive touch sensor {Electric capacitor touch sensor}

본 발명은 정전용량을 이용한 터치 센서로서, 더욱 상세하게는 정전용량 충전시간을 이용한 터치 센서이다.The present invention is a touch sensor using a capacitance, and more particularly, a touch sensor using a capacitance charging time.

요즘 사회에서는 터치 방식이 많이 사용되고 있다. LCD터치패널 등 많은 제품이 사용되고 있는데, 본 발명의 경우에는 집안에서 사용하는 가전제품의 On/Off식의 전원을 사용하는 제품에 응용할 수 있다. 그리고 현재 리모컨의 경우 Push Button방식의 스위치가 많이 사용되고 있고, TV에 있는 버튼도 그러한 형태를 여전히 많이 띄고 있다. 이 점을 이용한다면 리모컨의 크기도 줄일 수 있는 계기도 될 것이다. 인체와 접촉을 해야 정상동작이 되기 때문에 떨어뜨리거나 갑자기 어디에 눌리더라도 사람의 손이 아니면 동작이 하지 않기 때문에 현재 방식보다 유용할 것으로 보인다.  Nowadays, touch methods are used a lot in society. Many products such as an LCD touch panel are used, but in the case of the present invention, it can be applied to a product using an on / off power source for home appliances used in a house. In the case of the remote control, Push Button type switches are used a lot, and the buttons on the TV still have such a shape. If you take advantage of this, it will also reduce the size of the remote control. It should be in contact with the human body, so it will be normal operation, so even if it is dropped or suddenly pressed, it will be more useful than the current method because it does not work unless it is a human hand.

본 발명은 요즘 터치방식의 스위치가 많이 사용되고 있는 시점에 기존 형태와는 조금 다른 형태로 개발함으로서, 새로운 형태의 터치 센서를 만들고자 함이다. 이 센서를 응용하면 크기를 줄일 수 있고, 단순히 압력에 의한 것이 아닌 사람의 인체와 접촉되어야 정확한 동작을 하기 때문에 그 점에 있어서 유용할 것으로 보인다.The present invention is to create a new type of touch sensor by developing in a slightly different form from the existing form at a time when a touch type switch is used a lot these days. The application of this sensor can be reduced in size and useful in this regard because it can be operated correctly only by contacting the human body, not simply by pressure.

캐패시터의 기능을 이용한 것이기 때문에 한쪽 면에는 도체가 있을 것이고 그 사이에 절연테이프가 있을 것이다. 그리고 나머지 도체면은 사람의 손가락이 대신하게 될 것이다. 전압 상승이나 충전시간이 있는데 이 시간이 매우 짧을 것이다. 그래서 그 시간을 측정할 수 있는 정확한 실험장치가 필요하게 될 것이다. 오실로스코프의 경우 확인할 수는 있으나 수 usec이기 때문에 완벽한 시간측정은 어려운 것 같다. 이 시간을 측정하여 프로그래밍한다면 시간을 측정할 수 있을 것이다.  Because it uses the function of a capacitor, there will be a conductor on one side and an insulating tape in between. The rest of the conductor surface will be replaced by a human finger. There is a voltage rise or charge time, which will be very short. So you will need an accurate experimental device to measure the time. In the case of an oscilloscope, you can check it, but because it is a number usec, perfect time measurement seems difficult. If you measure and program this time, you can measure it.

앞서 말한것처럼, 본 발명은 일종의 스위치 역할을 하는 것이다. 그러나 기존 터치 센서와는 약간 다른 형태를 이용한 것이다. 도체의 한 극면과 그리고 다른 극면은 사람의 손가락, 유전체 역할로는 절연테이프가 함으로써 기존의 터치센서와 비슷한 역할을 한다. 그러나 구성방식이 다른 것이다.  As mentioned above, the present invention serves as a kind of switch. However, it uses a slightly different form from the existing touch sensor. One side of the conductor and the other side of the conductor is similar to the existing touch sensor by using human tape and dielectric tape as insulating tape. But the configuration is different.

여기서 본 발명에 대한 자세한 설명을 하고자 한다.Herein will be described a detailed description of the present invention.

기본적인 구조로는 프로그래밍할 칩과 캐패시터, 저항 등을 이용하여 회로를 구성한다. 그리고 인체의 손가락이 닿기전에는 일정전압까지 상승하기 까지의 시간이 있을 것이다. 사람의 손가락이 캐패시터의 한면이 될 것이다. 그리고 다른 한면은 도체가 그 역할을 대체할 것이고, 유전체의 역할은 절연테이프가 할 것이다. 이럴 경우 사람의 손가락이 닿을 경우 일정전압까지 올라가는데 시간이 변화할 것이다. 그 시간을 측정하고 그 시간을 이용한다. 그리고 그 시간을 측정하여 코딩했다면 사용자가 원하는 동작이 실행될 것이다. 만약 LED에 불을 켜기 위해서 프로그래밍 되어 있다면, 먼저 그 시간을 계속 관찰할 것이고, 관찰한 값이 맞다면 LED에 불이 들어오도록 할 수 있다는 것이다. 스위치처럼 On / Off의 역할을 하는 것이므로 터치 센서 하나가 여러 개의 동작을 할 수는 없다. 그러나 여러 개의 스위치를 배선하고 좌표를 이용하여 프로그래밍한다면 많은 센서를 구현하여 다양한 동작을 구현시킬 수 있을 것이다. 또 적은 비용으로 여러 개의 터치 센서를 만들 수 있기 때문에 비용면에서도 유리한 터치 센서가 될 것이다.The basic structure consists of a chip to be programmed, a capacitor, and a resistor. And before the fingers of the human body will have time to rise to a certain voltage. The human finger will be one side of the capacitor. On the other side, the conductor will replace its role, and the dielectric will play the insulating tape. In this case, if a person's finger touches, the time will change to reach a certain voltage. Measure the time and use that time. And if you measure and code that time, you'll get the action you want. If the LED is programmed to light, we will continue to observe the time first, and if it is correct we can have the LED light up. Since it acts as On / Off like a switch, a single touch sensor cannot operate multiple actions. However, if you wire several switches and program them using coordinates, you will be able to implement many different sensors by implementing many sensors. In addition, it is possible to make multiple touch sensors at a low cost, which will be advantageous in terms of cost.
