It's a Wheatstone bridge, a very well-known circuit that's used to measure resistance very accurately. That's about it. You can slap one together at home very easily. There's nothing special in this device that would even benefit from right to repair, any halfway decent engineer or hobbyist can figure it out. It's like wanting to repair a desk lamp, you don't need schematics or data sheets to do that.

While they are still essentially measuring galvanic skin response, modern ones have a lot more going on internally.
