摘 要：
To realize normal force and shear force perception,a fully compliant capacitive tactile sensor was designed for bio-inspired skin sensor array. The pressure-sensitive unit was constructed with silicone rubber as flexible substrate and silver conductive adhesive as flexible parallel-plate capacitor. The working principle and the structure design of capacitive flexible tactile sensor were introduced. The sensing information acquisition and processing system was also designed and implemented. When the normal load measurement ranges from 0 to 5 N with shear load measurement ranging from 0 to 3 N,the measured sensitivities are 6. 78 f F / N and 11. 45 f F / N,respectively. The experiment results indicate that the flexible capacitive sensors array and the capacitive signal extraction system have good stability and sensitivity for artificial skin to achieve tactile perception.
