XR hardware needs actors, this is about sensors.

An actor that changes temperature is a heater or maybe something like a peltier element, that can heat and cool. A sensor is the opposite: a thermometer that measures what temperature is somewhere.

Needless to say these are fundamentally different technologies. Sure, you need one to develope the other: e.g. to create a temperature sensing skin with high spatial resolution, you will need to generate precise spatial temperatures to test the whole thing.
