Brief description for the project:

The previous artificial skins were far away from perfection, so a new artificial skin is proposed in this project that has better sensing experience and better resolution.The artificial skin proposed here is meant to use for a bionic robot arm. It uses optical resonators to sense temperature and pressure. The materials are selected from four materials which are polydimethylsiloxane 60:1, polydimethylsiloxane 10:1, polymethylmethacrylate and silica. A deformation simulation is done to determine the materials and another one to determine the structure of the micro-spheres. A layering style is proposed for the skin. The dimensions is chosen in a way to mimic the natural skin. The optical fibers are added coupled to the micro-spheres. The skin is integrated with the arm solving any issue that rises. This work is applicable and can be improved later by finding better connection of optical fibers within the skin.

Challenges of the project:

It is project that the optical resonators showed better resolution than its counterparts in the field of sensing. Comparing the results of using optical resonators with the best electronic sensing, it is shown that optical resonators have better results due to the high quality factor of the optical resonators. High quality factor is a result to the light trapped inside the optical resonators. Besides that, the size of the micro-spheres that is near to the size of the natural skin cells gives a better resolution than any previous artificial skin.
