| Summary: | Amputees seldom experience from physical difficulties due to their incapability to use their extremities. To aid the amputees in acquiring an operative replacement fingers at a feasible cost, a 3D printed prosthetic fingers model interfaced with Readout Interfacing Circuit (ROIC) and a microcontroller is presented. A resistive-voltage as well as sensitive active bridge circuit for ROIC has been proposed for measuring very small resistance changes of a tactile sensor attributable to vary the gestures of the prosthetic fingers. To allow more than one prosthetic fingers' motion, two servo motors are embedded which offers two choices of gestures depending on the resistance of the tactile sensor. An experimental result of ROIC has been compared with conventional bridge circuit. The result reveals that the active bridge circuit is more sensitive than conventional full bridge circuit. © 2015 The Authors. |
