摘要
压力传感器仍然面临着将高灵敏度与宽检测范围相结合的挑战.基于此,我们设计了一种拉-压转换(TC)结构,并将其与变刚度策略相结合来制造压力传感器件.该结构能够将二维可拉伸材料的传感性能转换为三维可压缩设备的传感性能.传感和机械性能可以使用模拟和理论计算进行设计.斜面结构能够在24.3 N范围内提供线性传感.变刚度设计策略使传感器能够以高灵敏度(3.5 N-1)感知较小载荷,并具有宽的检测范围(0.002-24.300 N,扩展范围82.6 N).此外,该传感结构可以在水下环境中稳定工作.这种使用二维可拉伸应变传感器作为传感单元来开发压缩传感装置的设计策略将为未来提供新的思路.
Abstract
Pressure sensors still face the challenge of combining high sensitivity with a wide detection range.In this study,we designed a tension-compression conversion struc-ture and combined it with a variable stiffness design strategy to fabricate pressure-sensing devices.The structure can con-vert the sensing properties of two-dimensional(2D)stretch-able materials into the sensing properties of 3D compressible devices.The sensing and mechanical properties can be de-signed through simulations and theoretical calculations.The slope structure provides linear sensing within 24.3 N.The variable stiffness design strategy enables the sensor to sense a small load with high sensitivity(3.5 N-1)with a wide pressure range(0.002-24.3 N,with an extended range of 82.6 N).In addition,the sensing structure can work stably in an under-water environment.This design strategy of using 2D stretch-able strain sensors as the sensing unit to develop a compression sensor device will provide new ideas for future sensor design.
