In this study, we developed a flexible tactile sensor that scans the surface to detect the stiffness distribution. Note that the sensor does not need to know the displacement or strain of the target surface.Endoscopic palpation is a promising technology to detect tumors that have larger stiffness than normal tissues. The stiffness can be deduced by acquiring the load applied and the displacement, whereas the displacement or strain of the tissue is difficult to obtain given that endoscope has an arbitrary shape when in use and the tissue surface is not flat. In this study, we propose a new stiffness sensor composed of four strain gauges with different Young's modulus to detect the target without measuring the strain. The developed flexible sensor uses encapsulated liquid metal as the electrodes and can scan the surface.
