How Does Prosthetic Hand Work?

Prosthetic hand is an artificial limb that operates similarly to a natural hand in the human body. This technological marvel restores the user’s ability to move as a natural hand would. The prosthetic hand receives signals from the muscles using an advanced mechanism and moves accordingly. So, how does a prosthetic hand work, and how is this miraculous technology controlled?

Working Principle of a Prosthetic Hand

The working principle of a prosthetic hand relies on receiving signals sent by the user’s muscles. These signals from the muscles are detected through sensors embedded within the prosthetic hand, enabling the hand to move accordingly. This allows the user to control the prosthetic hand much like a natural hand.

The working mechanism of a prosthetic hand is highly advanced and requires the coordinated operation of multiple components. These components include motors, sensors, microchips, and articulated joint systems. When these components come together, the prosthetic hand provides the user with the movement capabilities similar to that of a natural hand.

What is Prosthetic Hand?

Prosthetic hand is designed to provide a functional hand for individuals who have lost their limb. It helps the person perform daily activities while also offering a natural appearance for aesthetic purposes.

The use of a prosthetic hand can be customized according to the individual’s needs and activities. For instance, a different control mechanism might be employed during sports, while more precise control might be necessary for daily activities. This allows the prosthetic hand to provide the user with a wide range of motion and flexibility.

What is a Prosthetic Hand?

The components of a prosthetic hand are fundamental elements that enable the smooth operation of a complex mechanism. Each of these components ensures the proper functioning of the prosthetic hand and maximizes its benefits for the user.

The main components of a prosthetic hand include:

• Electronic Control System: This system can be thought of as the brain of the prosthetic hand, responsible for controlling its movements. It detects signals from the user’s muscles and adjusts the movements of the prosthetic hand accordingly.
• Mechanical Structure: These are the mechanical components that form the skeleton of the prosthetic hand and provide its movement capability. These parts enable elbow, wrist, and finger movements, offering the user a natural experience.
• Motors: These are the motors responsible for enabling the movement of the prosthetic hand. They act based on specific commands and carry out the desired functions.
• Sensors: These are sensors that detect the environment around the prosthetic hand and enable the user to feel objects they interact with. This allows the user to control the prosthetic hand more accurately.

How to Control a Prosthetic Hand?

The control of a prosthetic hand is an important step in providing functionality to users in their daily lives. This control process typically occurs through electromyography (EMG) signals, muscle contraction sensors, and sensitive touch sensors. Users can control the prosthetic hand by moving their muscles or through delicate touches.

Among the technologies used for controlling a prosthetic hand, myoelectric control systems and neural control systems are prominent. Myoelectric control systems direct the movement of the prosthetic hand by detecting muscle activity, whereas neural control systems perform movements using brain signals.

Prosthetic hand users can benefit from the education and rehabilitation programs available at our clinic while learning control techniques. These programs enable users to maximize the potential of their prosthetic hand and help them perform daily activities more easily.
