In a First, a Prosthetic Limb Can Sense Temperature Like a Living Hand (www.smithsonianmag.com)

The device provides a realistic sense of hot and cold in the missing “phantom” hand by delivering thermal information to nerve areas on the amputee’s residual limb that the brain believes are still connected to the missing hand.

It sounds like instead of a different stimulus to differentiate between hot and cold (like what I think you describe) the limb in the article is able to stimulate nerves that feel “hot” vs “cold”

Either way that’s super cool you saw that back then, always awesome to see how stuff moves along over the years.
