Description

As of my last update in September 2021, touch bionics or myoelectric prosthetics have been developed to aid individuals who have lost their limbs, including below-elbow amputees. Touch bionics refer to the use of myoelectric prosthetic limbs that can be controlled using signals generated by the residual muscles in the user’s limb.

Below-elbow touch bionics typically involve the use of a myoelectric prosthetic hand. Here’s how it generally works:

Myoelectric Control: The prosthesis is equipped with electrodes that are placed on the surface of the residual limb. These electrodes pick up electrical signals produced when the user contracts specific muscles in their residual limb.

Signal Processing: The signals from the electrodes are transmitted to a microprocessor located within the prosthetic hand. The microprocessor interprets these signals and translates them into specific movements for the prosthetic hand.

Prosthetic Hand Movement: The prosthetic hand’s motors and mechanical components receive the processed signals from the microprocessor and move accordingly, mimicking the hand’s intended actions.

Sensors for Feedback: Many modern myoelectric prosthetic hands also incorporate sensors in the fingertips that provide feedback to the user about how much force they are exerting when gripping objects.

Customization: Each prosthetic is custom-fitted and calibrated for the individual user to ensure optimal functionality and comfort.
