Slip sensors for the control of the grasp in functional neuromuscular stimulation

In this paper we present the results of research on the role of slip and force sensors in the control of grasp by means of functional neuromuscular stimulation (FNS) when applied to plegic subjects. From our study, it emerged that a reliable control strategy can be more efficiently based on the slip signal than on the signal related to the force exerted by the fingers. A prototype system involving both slip detectors, realized by means, of inductive transducers, and force sensors has been designed.
