This research has shown for the first time that the physical dimensions of small surface patterns in an object
surface are detectable from sensors integrated into the fingertip and mechanical links of a prosthetic hand. A further
novel aspect of this work is the use of the standard deviation of data used in the analysis.
Charge amplifiers are used to extract the signal from the piezoelectric sensors when an object Worldwide, prosthetic hands are being developed that have multiple actuators in order to improve their
functionality [1]. As part of this development, sensors will be required for feedback information to electronic
controllers or the amputee. There has been little investigation of texture sensors in prosthetics though more in
robotics [2].
