An electrical impedance tomography (EIT) technique is employed to estimate changes of resistance distribution on the sensor caused by fingertip contact. To compensate for the rebound elasticity of the elastomer and achieve real-time contact sensing, an adaptive baseline update for EIT is utilized. The baseline updates are triggered by fingertip contact and movement detections.
