Abstract

This study introduces a novel method for improving iontronic capacitive pressure sensors by substituting traditional electrodes with piezoresistive graphene-polyurethane (G-PU) sponge. Adjusting the sponge’s resistance variation range allows for precise control of the interfacial electric double layer (EDL) capacitance, which facilitate to the performance of the sensor with a linear range of 0-2300 kPa and a linearity of 0.98. This approach provides high-resolution detection of 35 kPa across an ultra-wide pressure range exceeding 2000 kPa. This method effectively addresses the need for diverse application requirements across varying pressure intervals in advanced pressure sensing systems.

在离子压力传感器中实现超宽线性范围的电阻调谐电极策略

本文介绍了一种用压阻性石墨烯-聚氨酯（G-PU）海绵代替传统电极改进离子电容式压力传感器的新方法。调整海绵的电阻变化范围，可以精确控制界面双电层（EDL）电容，从而使传感器的线性范围为0-2300 kPa，线性度为0.98。该方法可在超过2000 kPa的超宽压力范围内提供35 kPa的高分辨率检测。该方法有效地解决了先进压力传感系统中不同压力区间的不同应用需求。
