British Engineer Develops First 3D Printed,sensor-controlled Prosthesis,designed For Children Under Two

Jan 16, 2020

This lightweight prosthesis is equipped with soft grasping fingers, and the armband is equipped with sensors that detect the electrical signals naturally transmitted by the muscles. Allows young children to hold and pick up objects like natural arms.

Although muscle-stimulating prostheses are commonly used by adults, a team at the University of Lincoln in the UK has developed a new, smaller device that is the first to convert the same technology to a size suitable for young children.

 

Prior to this, the production of prosthetics for children under two years of age was not only costly, but has also been considered problematic because the rapid growth of children means that these prosthetics need to be replaced frequently. By using 3D printing technology, SIMPA (soft-grip infant electromyography prosthesis) is cheaper to make than traditional prosthetics, and can be customized to the size of the child without the need for traditional plaster casting technology.

 

Another problem with existing child prostheses is the high rejection rate. The installation of early functional myoelectric devices has been shown to reduce this rejection rate, which can be achieved by using new SIMPA devices.

 

"Many traditional active prosthetics are not suitable for young children because they are time consuming and heavy. We The proposed system will use a seven-channel child armband with a motion sensor to benefit infants and become familiar with active prosthetics, and there is evidence that the sooner they are contacted, the more likely the prosthesis will be accepted and used throughout life. "

 

"To date, the device has been tested for grip and effectiveness with a range of everyday items, including toys, bottles and blocks, but the next phase of the project is to test prototype designs on young children."

 

Dr. Gohel added: "We plan to use algorithmic training, use games to interact with young children, and adjust the system to the state of 'armband acquisition signals'.
