<pre>How to create hyper-realistic skin for bionic prostheses

Over the centuries, manufacturers of limb prostheses have sought to maximize – externally and functionally – to bring them closer to the missing “original”. Just recently, TouchBionics published a video on YouTube, detailing the stages of creating hyper-realistic skin for limb prostheses in a “set” with nails, hair and texture.

Everything begins with fixing the external physical characteristics of the limb (in this case hands) and creating it a digital model for subsequent adjustments for the selection of skin, hair, freckles, veins and nail forms.

The casting of the hand shape is then carried out: first, the hand is covered with a special compound, which after drying completely reproduces its configuration in the form of a kind of glove. Then another substance is poured into it, which, in turn, repeats the impression of the hand after cooling, and the “glove”, which has become unnecessary, is removed.

The next step is applying a metal film to the product, after which the future denture is filled with silicone. It is he who reproduces the final configuration of the limb in the form of a transparent, flexible glove.

In conclusion – tuning, when the skin color is selected, the shape of the nails, veins, hairs and even tattoos. After “vigorous testing” the prosthesis is equipped with electronics and mechanics.
