摘要

我们提出了一种具有三维网络结构的中空聚二甲基硅氧烷(PDMS)泡沫材料制成的高灵敏度电容式压力传感器。泡沫的刚度由PDMS溶液的粘度来调节。制备的PDMS-30 (PDMS 30 wt%)泡沫具有极高的孔隙率(>?86%)，约为裸PDMS (PDMS 100 wt%)泡沫的19倍。使用泡沫制成的电容式压力传感器具有高灵敏度，良好的压缩性(高达80%的应变)，并且在2000次循环测试中具有一致的输出特性。

Hollow polydimethylsiloxane (PDMS) foam with a 3D interconnected network for highly sensitive capacitive pressure sensors

We propose a highly sensitive capacitive pressure sensor made of hollow polydimethylsiloxane (PDMS) foam with a three-dimensional network structure. The stiffness of the foam is adjusted by the viscosity of the PDMS solution. The fabricated PDMS-30 (PDMS 30 wt%) foam shows extremely high porosity (>?86%) approximately 19 times that of bare PDMS (PDMS 100 wt%) foam. Capacitive pressure sensors fabricated using the foam possess high sensitivity, good compressibility (up to 80% strain), and consistent output characteristics in a 2000-cycle test.
