Anotācija Textile sensors have a wide range of applications in wearable monitoring systems due to their lightweight, elastic and flexible properties. The present paper is devoted to the comparative analysis of effects of pressure load on knitted pressure sensors of different shapes and their durability to washing. All the developed sensors are knitted using cotton yarns and copper coated acrylic yarns on a circular knitting machine. The sensor performance properties and durability have been tested experimentally. Each type of sensors was tested under quasi-static and dynamic loadings with various pressure forces. Relations between the applied pressure force and sensor sensitivity and responses were analysed. It was found that filled shape sensors are more sensitive to low pressures. Testing of the sensors under dynamic loads confirmed high repeatability of measurements and sensitivity even to small variations of the loading level. One of the most common problems of textile-based sensors that essentially restrict application of smart textiles is their care. Therefore, durability of the designed sensors to washing was been studied, as well. It was found that knit density affects sensor durability to washing. Sensors with a higher knit density showmore stable and uniform electrical resistance increase, whereas sensors with a lower knit density show unstable durability and higher variation in electrical resistance changes. Also, configuration of the sensors affects the electrical resistance changes due to washing
