基于电容感应的柔性压力传感器以其低能耗和优异的性能成为近年来的研究热点。在实际应用中，广泛的检测和低成本的批量生产的柔性压力传感器是理想的。本文提出了一种基于结构弹性电极的宽检测范围电容式压力传感器，该传感器成本低，采用简单的微孔PE带成型方法即可批量生产。测试结果表明，该传感器的压力检测范围为0 ~ 45kpa。这是因为电容式传感器的上部结构在受到不同的外界压力时不断发生变化，使得传感器上部衬底的接触面积变大，上下衬底之间的距离变小。此外，该电容式压力传感器具有低检测极限（<300 Pa），超短响应时间（<50 ms）和高运行稳定性，可重复加载/卸载压力循环。该传感器具有良好的分辨率和语言识别能力，可用于脉冲监测。柔性电容压力传感器的低成本量产和宽检测范围为电子皮肤、接触式检测应用和可穿戴式医疗监护仪的发展奠定了基础。
Flexible pressure sensors based on capacitive induction have become a research hot-spot because of low energy consumption and excellent performance in recent years. In practical applications, a wide range of detection and low-cost mass-produced flexible pressure sensors are ideal. Herein, this paper presents a wide detection range capacitive pressure sensor based on a structured elastic electrode, which is low cost and can be mass-produced by a simple method of micropore PE tape molding. Test results show that the sensor’s pressure detection range is 0–45 kPa. This is because the upper structure of the capacitive sensor is constantly changing when subjected to different external pressures, so that the contact area of the upper substrate of the sensor becomes larger and the distance between the upper and lower substrates becomes smaller. In addition, this capacitive pressure sensor exhibits low detection limit (<300 Pa), ultra-short response time (<50 ms) and high operational stability for repeated loading/unloading pressure cycles. The sensor owns excellent resolution and can distinguish language, and the sensor can be used to monitor pulse. Low-cost mass production and wide detection range of flexible capacitive pressure sensors lay the foundation for the development of electronic skin, contact inspection applications and wearable healthcare monitors.
