电容式传感器（Capacitive Transducer）是一种将物理量变化（如位移、压力、湿度等）转换为电容值变化的电子测量装置。其核心原理基于平行板电容器的基本公式：
$$ C = frac{varepsilon_0 varepsilon_r A}{d} $$
其中：
通过改变公式中的任一参数（$A$、$d$ 或 $varepsilon_r$），即可实现物理量到电信号的转换。其典型工作模式包括：
变间距型
外力改变极板距离$d$，电容与距离成反比。适用于微位移测量（如振动传感器），灵敏度高但非线性明显。工业级产品精度可达纳米级（如Keysight精密测头）。
变面积型
机械运动使极板重叠面积$A$变化，电容与面积成正比。常见于角度/位置传感器（如汽车油门踏板位置检测），具有线性输出特性。
变介电常数型
介质成分变化引起$varepsilon_r$改变。用于液位计（如化工储罐液位监控）或成分分析仪（粮食水分检测），需考虑介质损耗补偿技术。
技术优势与典型应用
权威研究指出，现代电容传感器通过差动结构、屏蔽环设计及ASIC信号处理电路，可有效抑制寄生电容干扰，温度漂移可控制在0.05%/℃以内（IEEE传感器期刊，2019）。在生物医学领域，其非侵入特性使其成为植入式血压监测器的理想选择（ScienceDirect生物工程综述。
注：实际应用中需注意电磁屏蔽、湿度补偿及线性化校正等关键技术点。具体设计规范可参考IEC 61000-4电磁兼容标准。
