In this study, a highly sensitive and fast 3D finger-shaped tactile sensor was developed to provide a realistic tactile sense in robot fingers. 3D printed flexible artificial fingers are integrated with strain sensors using conductive powder, and the strain distribution caused by contacting objects is visualized by the electrical impedance tomography (EIT). Time required to solve an inverse problem of Laplace's equation was 15 ms, which was sufficient to perform the real-time artificial tactile sensing. Approximately 8 mm of two-point discrimination threshold was achieved in our present device.
