摘要

由于生物医学领域的各种应用，对柔性和可穿戴传感器的需求日益增加。尤其需要高灵敏度的传感器来检测来自身体的低信号。开发一种能够将最大输入信号转换为电输出的压力传感器是很重要的。本文研究了石墨烯压阻式压力传感器的设计和性能，采用方形膜片上的锯齿形压阻。在施加压力时，变形由膜片上方的压敏电阻感应。采用有限元方法研究了锯齿形压敏电阻对方形膜片的影响。在0-100 psi的压力灵敏度工作范围内，获得了优化设计的仿真结果。

A novel graphene pressure sensor with zig–zag shaped piezoresistors for maximum strain coverage for enhancing the sensitivity of the pressure sensor

The demand for flexible and wearable sensors is increasing day by day due to varied applications in the biomedical field. Especially highly sensitive sensors are required for the detection of the low signal from the body. It is important to develop a pressure sensor that can convert the maximum input signal into the electrical output. In this paper, the design and performance of graphene piezoresistive pressure sensors have been investigated by zig–zag piezoresistors on the square diaphragm. On the applied pressure, deformation is sensed by the piezoresistors above the diaphragm. Finite element analysis is carried out to investigate the effect of zig–zag piezoresistors on the square diaphragm. Simulated results for the optimized design are obtained for an operating range of 0–100 psi for pressure sensitivity.
