　　触觉是许多动物和一些植物的重要感觉通道，例如我们的手触摸某物时，我们的感官会有反应。不过对于计算机而言，其输入设备与人类接触无关，因为在进行、保持或中断物理接触（如触摸或释放）时，它不会没有反应。

　　正因如此，触摸感应输入设备为新颖的交互技术提供了许多可能性。其中，触摸传感器技术正在慢慢取代鼠标和键盘等机械物体。触摸传感器在不依赖物理接触的情况下检测触摸或接近。触摸传感器正在进入许多应用，如手机、遥控器、控制面板等。更重要的是，当前的触摸传感器可以取代机械按钮和开关。

　　带有简单的旋转滑块、触摸板和旋转轮的触摸传感器为更直观的用户界面提供了显着优势。触摸传感器在没有移动部件的情况下使用起来更方便、更可靠。触摸传感器的使用为系统设计人员提供了极大的自由度，有助于降低系统的总体成本，并且整体外观可以更具吸引力和现代感。

触摸传感器的工作原理是什么

　　一、触摸传感器的工作原理

　　触摸传感器也称为触觉传感器，对触摸、力或压力敏感，它们是最简单和有用的传感器之一。触摸传感器的工作类似于简单的开关，当与触摸传感器的表面接触时，传感器内部的电路闭合并且有电流流动。当触点松开时，电路断开，没有电流流过。其工作示意图如下所示：
