Abstract:

In order to obtain a flexible pressure sensor with high sensitivity, simple preparation process, light weight and air permeability, thermoplastic elastomer polyurethane (TPU) electrospun nanofiber membrane was used as a substrate and a dielectric layer and carbon nanotube conductive ink was used as an electrode coating to prepare a sandwich-structured nanofiber membrane-based flexible pressure sensor by ultrasonic welding. The relationship between pressure sensing properties and nanofiber membrane thickness and microstructure was studied. The results show that with the increasing of spinning time, the thickness and the tensile stress of the nanofiber membrane increase, while the elongation at break decreases. In the pressure range of 9.8-49 000 Pa, the sensitivity of the device decreases with the increase of the spinning time. When the spinning time is 1 h, the sensitivity of the device is up to 4.97 kPa-1. The nanofiber membrane-based flexible pressure sensor has the characteristics of high sensitivity and wide response range.

Key words: flexible pressure sensor, nanofiber membrane, electrospinning, thermoplastic elastomer, polyurethane
