Electromyography Sensor Controlled Bionic Hand for Disabled Persons

Abstract

The word “Bionic” is amalgam of domain Biology as well as Electronics. In today’s era, we come across new emerging technology which is rapidly evolving. Bionic hand is one of its kinds. However, with upgrade technology the demand for bionic hand will continue to increase day by day in upcoming years with wider awareness. The major purpose behind the project is to help an individual to improve the sensation, integration with the body and the control. The development and operation of bionic hand has been explained and controlled by Electromyography Muscle Sensor. Signals from an amputee muscle are gathered by bionic arms to function. The muscle sensor is the main component which senses electrical activity of our muscles and translate those activity which results in flexing of finger with the help of servo motors. 3-D printing is used in the design and construction of the bionic arm. The result we obtain here after demonstration is 80% movement of little finger, ring finger, middle finger and fore finger as well as 30% movement of Thumb finger. Along with this when pressure is strongly applied, the signals from the muscle goes to the sensor and hence result in approximate 75% movement of all five fingers together.
