SIMPA 3D printed prosthesis: built for toddlers at a relatively low cost

A team from the University of Lincoln in the Uk recently developed a cheap, user-friendly prototype of the prosthesis, led by Dr Khaled Goher,media reported. It is said to be the first 3D-printed, sensor-operated prosthesis for children under the age of two, known as The Soft-Grasp Infant Myo Myo Armelectric (SIMPA).

It is understood that SIMPA detects electrical signals from muscles in the limbs through sensors, which are then converted into instructions from the arm’s two-finger gripper.

In order to train children on which muscle movements are necessary and to align the microcontrollers of prosthetics with their unique physiological functions, the design team believes that this can be achieved through simple games.

Since SIMPA is 3D printed, it should be relatively cheap to replace your child as he grows. In addition, because the custom interface shape is determined by performing 3D scans of a child’s limbs, it does not require a routine plaster casting process like traditional prosthetics.

What’s more, Because it is lighter than other prosthetic arms, SIMPA should be more acceptable to young children. This is an important consideration because the researchers point out that the sooner a child comes into contact with a prosthesis, the less likely they are to reject it because it is too bulky.

“Many traditional active prostheses are not suitable for young children because they are very time-consuming and heavy,” Goher said. The system we propose will use a seven-channel child armband with motion sensors to benefit young children and become familiar with active prosthetics. “
