Abstract: This invention relates to a device for sensing interaction with its surrounding environment, the device including: a plurality of sensing points (11); a plurality of detectors (12), each associated with one of said sensing points (11) and located remotely therefrom; a plurality of channels (14) which connect said sensing points (11) to said detectors (12) and provide a communication pathway therebetween; and communication media filling the channels, wherein each detector (12) is in communication with the associated sensing point or points (11) through one of said channels (14) and the medium in said channel (14) is arranged to transmit, transfer or transduce an interaction of the sensing point (11) with its surrounding environment to the detector (12) through the channel (14). The invention also relates to prosthetics which incorporate such devices.
