Abstract:
We present the design and development of a sensor unit for the acquisition of
electromyography (EMG) signals in human walking. This is done by placing
multiple sensors in the muscles involved in the knee and ankle movement of a
human leg when walking. The electrical output of the sensors is amplified, filtered
and smoothed with a designed cascaded electronic circuit. The angle of the knee
and ankle movement when walking is monitored by the sensor unit.
