The skin, our first and main interface with the world. This organ, which covers our entire body, gives us many sensations such as pressure, temperature or pain.

The loss of a limb, in addition to a loss of mobility, leads to a loss of sensation due to the disappearance of the skin. Our current prostheses focus on the recovery of mobility, without taking into account the sensitivity of the limb and its appearance. This often leads to rejection of the prosthesis, because it can't be used or can't be assimilated to the body of the wearer.

We are intimately convinced that the recovery of the senses, as well as the mimicry of the human body, are the key to the evolution of our prostheses. The particularities of the skin do it the ideal candidate for the realization of more complete prostheses. This is why we are working on the development of a synthetic skin that recreates the sensation of touch while having an appearance close to human skin. To allow a wider use, we have imagined it in assembly so that it can be adapted in shape and size.

Our solution, therefore, consists of creating "bricks" of skin that can be assembled by hand. Each brick mimics the different layers of human skin (epidermis, dermis, etc...) to recreate the texture and flexibility of human skin. The pressure is calculated with an insulated capacitive matrix in a flexible Farraday cage. This allows it to maintain the precision of capacitive technology while being sensitive to all materials. The different skin bricks are linked to a node allowing them to be identified and positioned in relation to each other. Each node communicates externally via Bluetooth to a hotspot which takes care of representing the skin matrix virtually.
