【 摘 要 】

tsThe sensors displayed high sensitivity (8962.7), fast response time (60 ms), outstanding stability and durability (> 10,000 cycles) and widely workable stretching range (0–160%).A theoretical approach was used to analyze mechanical property, and a model based on tunneling theory was modified to describe the relative change of resistance.Two equations were proposed and offered an effective but simple approach to analyze the change of number of conductive paths and distance of adjacent conductive particles.
