Abstract
We propose a new type of soft areal tactile sensor with pressure sensitive conductive rubber using inverse problem analysis. The significant feature of this type of sensor is that we don't need complex wiring in the center region, because we can estimate the conductivity change (i.e. pressure toward the sensor) in the center region based on electrical impedance tomography (EIT) technique that is a kind of inverse problem analysis. We will discuss the effectiveness of this type of sensor by verification of the prototype sensor system ability.
