Abstract

A device aimed at restoring the sensory feedback in amputees is presented. Biphasic current pulses can be generated and delivered to the Peripheral Neural System (PNS) through neural electrodes. The current pulses can be controlled in terms of amplitude, width and frequency. Moreover, the system can be configured to generate customized waveforms. The device is based on an IC implemented on a 0.35um HV process and includes a voltage booster and a programmable current DAC, allowing to deliver the programmed current even in case of high impedance contact at the electrode-tissue interface. The system has been implemented and successfully tested by means of in-vivo experiments with rats.
