The design of a flexible digit towards wireless tactile sense feedback

This paper describes research on the embedded signal processing function for a flexible digit with the feedback of tactile sense, such as is appropriate to endoscopy and other minimal access surgery. The paper describes the nature of the flexible digit and its associated sensor arrays and concentrates on the nature of the signal processing function and the problem of embedding it an application specific digital system. The paper also focuses on the need for wireless or ´tetherless´ sensing in such systems.
