Design of Prosthetic Finger Replacements Using Surface EMG Signal Acquisition

At times, people are born with physical disabilities with respect to their limbs, or lose their fingers as a result of various scenarios. This work aims to achieve maximum replication of the human finger through the use of mechanical prosthetic replacements using surface-based acquisition of Electromyogram (EMG) bioelectric signals pertaining to the underlying muscle tissue. This can be achieved by harvesting a muscle's electrical activity at the required points, which control human limb and finger movement, and tapping, amplifying and converting that electrical signal to use it to drive a prosthetic replacement that is controlled by a microcontroller and servo motors.
