Abstract

The invention discloses an elastic array pressure sensor, which applies an elastic conductive fiber technology to an array pressure sensor to realize a technology of detecting pressure under the condition of large deformation. According to the invention, the elastic conductive yarns are arranged on two sides of the sensing layer as electrodes and are sewn on the sensing layer, and the sensing layer is made of conductive cloth, so that the whole sensor is lighter, thinner and softer; according to the preparation method of the elastic conductive yarn, existing spinning equipment and a mature ring spinning process are used, the manufacturing process is simple, the cost is low, and large-scale production is easy to achieve; according to the elastic conductive yarn, when the elastic conductiveyarn is dynamically stretched, the conductive core-spun yarns spirally wound on the outer sides of the elastic fiber filaments are insulated from one another and can extend in the direction of the elastic fiber filaments, the effective conductive length of the elastic conductive yarn is kept unchanged, the resistance value is stable and unchanged, and meanwhile the requirements for flexibility andstretchability are met.
