Flexible Tactile Sensor Based on Conductive Rubber and Sensing Mechanism

Conductive rubber material has been widely investigated as a sensor and transducer material due to its high piezoresistive, conductive properties. In this paper, we report on a flexible tactile sensor which is based on conductive rubber filled with carbon black. Firstly, a physical model related linear elasticity mechanics and franklinic analogue method is deduced. Then the sensing mechanism of flexible tactile sensor based on conductive rubber is discussed based on the physical model and used as the principle in designing tactile sensor. Theoretical analysis and simulations both verify the structure is reasonable. Copyright © 2013 IFSA.
