Summary: Bio-robot with tactile sensors can simulate human touch on surface characteristics of an object, but obtaining subsurface information is difficult. In this study, a smart bionic finger with subsurface tactile tomography capability is introduced. The bionic finger has an integrated tactile feedback system that allows it to quantitatively respond to force. By setting up force thresholds, the bionic finger can generate layer-by-layer slice images of materials to reveal their internal structures. The feasibility of this subsurface tactile tomography is demonstrated by reconstructing a subsurface 3D profile of artificial human tissue and a flexible circuit system. This bionic finger opens up a nonoptical method for nondestructive testing of the human body and flexible electronics.
