Abstract

Abstract In the capacitive proximity sensing method, arranging multiple sensing electrodes makes it possible to obtain the three-dimensional position of a nearby object. The author has developed a capacitive proximity sensing method using LC resonance in three reactance elements. In this method, the detectable area can be greatly extended by the floating electrodes, which are capacitively connected to the sensing electrode. By connecting multiple floating electrodes in series, the detectable range can be extended up to the length of the array of floating electrodes. When these electrodes are arranged on a frame, the region surrounded by the frame becomes the detectable area. By applying this frame on any surface, it is possible to make the surface within the opening of the frame a non-contact operating panel, which can be applied as a gesture input device.

电容式三维接近传感器中浮动电极可探测区域的扩展

在电容式接近传感方法中，通过布置多个传感电极，可以获得附近物体的三维位置。作者提出了一种利用LC谐振在三个电抗元件中进行电容式接近传感的方法。在该方法中，通过与传感电极电容连接的浮动电极可以大大扩展可检测区域。通过串联多个浮动电极，可将检测范围扩展到浮动电极阵列的长度。当这些电极排列在框架上时，被框架包围的区域成为可检测区域。通过将该框架应用于任何表面，可以使框架开口内的表面成为非接触式操作面板，可作为手势输入设备应用。
