摘要

解决电子垃圾污染问题亟需生态友好型战略。由可降解聚合物构建的绿色电子产品已引起广泛关注。本文利用可生物降解的聚乳酸（PLA）无纺布制造了压阻/电容双响应压力传感器（DRPS）。我们采用了一种 MWCNTs/PLA 压阻织物 (CPPF)，将其与电容式压力传感器结合在一起，取代了传统的压缩介电层。与纯电容式传感器相比，DRPS 的双重响应影响与多孔性不同。双电阻/电容设计提高了传感器在宽压力范围内的灵敏度。DRPS 可以测量各种压力，从轻微的树叶负载到沉重的脚步声和人体关节的弯曲运动。

Biodegradable pressure sensors with high sensitivity and wide detection range via a piezoresistive/capacitive dual response†

Eco-friendly strategies are strongly needed to address the issue of e-waste pollution. Green electronics constructed from degradable polymers have attracted widespread attention. In this paper, a piezoresistive/capacitive dual-response pressure sensor (DRPS) utilizing biodegradable polylactic acid (PLA) nonwovens was fabricated. Instead of a conventional compressive dielectric layer, we employed a MWCNT/PLA piezoresistive fabric (CPPF), incorporating it with a capacitive pressure sensor. The DRPS's dual response impact differs from porosity compared to purely capacitive sensors. The dual resistance/capacitance design enhances sensor sensitivity across broad pressure ranges. The DRPS can measure diverse pressures, from light leaf loads to heavy footsteps and bending motions of human joints.
