No, I'm not aware of any thermal sensor used for FaceID. It builds an image of your face using an IR camera paired with an IR projector just like the first generation Kinect (made by PrimeSense that was bought by Apple in 2013). Keep in mind that this is near IR, not far IR that's used in thermal imaging.
