Voltage Controlled Stimulator For Nerve Conduction Study

Use of an appropriate stimulus is essential to acquire proper nerve conduction signal. This paper presents a voltage controlled stimulator that generates proper voltage to be applied over the skin for nerve conduction study (NCS). Unlike conventional stimulator, the designed stimulator is based on battery which is suitable for portable nerve study machines. The recording and signal processing involve signal conditioning circuit that consisting of filter and amplifier circuits. The conditioning circuit amplifies and filters low-level biomedical signal, usually, falls in mV. Experimental setup has been tested and demonstrated using real-time data collected in laboratory. The system is adaptable to the subjects with safety.
