Back in the mid – nineties I was working on many different theories and they relied on the need of a robotics sense of its environment. I came up with many designs but this one I have always wanted to test.

I will forgo the reasons why I have not for now.

By whatever means; laser, chemical etching, nano tech, ect. You’ll create a simple coil pattern on the base metal. Smaller around the fingers, larger in lower response areas. A thin coating is used to separate the coils from the base metal, the coil ending to connect with the base.

Mix a ferromagnetic (none magnetized powder) to the skin compound. Using an electromagnetic field to spread them evenly and point them in one direction.

After curing magnetize the ferromagnetic material.

Two layers n to n or s to s is used and depending in the formula of the skin the outer layer should respond to temperature before the enter layer giving a response to temperature.

The small coils should pick up the difference when the alignment of the magnetic field is disrupted.
