A Linear Wide-Range Textile Pressure Sensor Integrally Embedded in Regular Fabric

This letter presents an improved design of a textile pressure sensor. The sensor is constructed of conductive yarns and a dual-layer piezoresistive polymer as the sensing material. By using intarsia knitting technique, this sensor can be integrally embedded in regular cotton fabric. Experimental results show a linear sensing response over a wide pressure range up to 1000 kPa.
