First off, for my EE100 class I chose to replicate the industrial electrical blankets that are out there. With that being said, I do own one and can tell that there are some kind of conductive, insulated wires (copper?) that run throughout the blanket which generate the heat. And of course, the blanket plugs into a control which dictates the power level of the heat. My main questions are what kind of raw materials will I need? My guesses are as follows: 1.) Some type of conductive wire and plastic shield for the wire? 2.) Some polymer/material that can insulate and protect the blanket from burning. 3.) I want to incorporate a lithium battery so that no wall plug is needed. 4.) And the heat controller might be a bit complicated so I won't include this in my project. And of course I will need some guidance on how to make the circuit from the battery to the wires and how to even control how much heat is generated by the wires (clueless here). P.S. I am not an expert EE so please no too-technical terms, haha. If more info is needed just ask! I appreciate all of the replies.
