第一代电容笔为被动式电容笔，未内置电路，工作原理为通过导电材质与触控屏接触来改变屏幕电容，从而实现触控效果；由于其笔尖较粗，导致触控精度 较低，逐步被淘汰。 第二代电容笔为主动式电容笔，是目前市场主流产品，内设电子电路结构及电容传感器，电容笔通过笔尖发射驱动信号，与屏幕感应层之间耦合电容进行工 作，触控屏幕通过扫描不同通道的电容值的变化来识别电容笔的坐标位置；同时，通过解电容笔发射的下行打码信号来识别笔尖发射的数字信息，例如电容 笔的 ID、按键信息以及压力信息等；另外，电容笔内部也通过增加蓝牙、电容传感器、六轴传感器、线性马达等部件，从而实现多维度交互、振动反馈、 隔空操作、语音识别等功能。 主动式电容笔/智能笔指用于触摸屏设备的触控笔，与传统的电阻式触控笔或被动式电容笔有所不同，主动式电容笔本身包含有源电子元件，如电路和电 池，使其能够主动地与触摸屏设备进行通信，主动式电容笔提供了更高的精准度和交互性，使用户能够更自由地进行创作、绘图、书写和其他操作 2010 年以来，电容笔行业的发展历程具体如下： （1）电容笔行业简介 电容笔指利用导体材料模仿人体（通常是手指）的具有导电特性、用来触控电容式屏幕完成人机 ...
