Rather than just synthetic fur - imagine a coat (furry or not) that is "alive" and generates it's own heat to keep you warm. Maybe it "feeds" on your sweat and dead skin cells? Or you feed it at night in some manner?

Every time I see one of these articles on "bio-robotics" or whatever you want to call them, I always think back to sci-fi like Dune (Axlotl "technology") and/or Blade Runner (replicants, artificial eyes, etc); a future where the line between the artificial and the natural is very, very blurry.

Sweat happens when your body needs to remove excess heat, so using it to heat your body back (even if thermodynamics allowed for it) would be... kind of counterproductive. But being able to feed it with something overnight and have it slowly radiate out the heat would be a nice thing for winter months. Beats electric heating.
