Design of a modular tactile sensor and actuator based on an electrorheological gel

چکیده
We present the design of a modular tactile sensor and actuator system for observing human demonstrations of contact tasks. The system consists of three interchangeable parts: an intrinsic tactile sensor for measuring net force/ torque, an extrinsic tactile sensor for measuring contact distributions , and a tactile actuator for displaying tactile distributions. The novel components are the extrinsic sensor and tactile actuator which are " inside-out symmetric " to each other and employ an electrorheological gel for actua-tion.

Mechanical properties of biological tissue represent important diagnostic information and are of histological relevance (hard lesions, "nodes" in organs: tumors; calcifications in vessels: arteriosclerosis). The problem is, that such information is usually obtained by digital palpation only, which is limited with respect to sensitivity. It requires intuitive assessment and does not allow quanti...
