Heat Inside

I have yet to find on the web to any success the creation or implementation of heated gel within a computer keyboard wrist wrest. A big factor in the situation with Carpal Tunnel Syndrome prevention and treatment is keeping your wrist comfortable and warm to prevent stiffness and or numbness/tingling. With my product I am proposing to create for capstone, I hope to use a heating element with sensor that will allow the user to adjust a temperature setting to his/her own personal preference along with a sort of memory foam/gel concentrate to allow for a more productive sitting. With all the research I have done it seems like heat is a critical factor, but no known devices or companies have this factor implementated in any of their products
