Manchester's platinum pressure paint shrinks the heat correction wind tunnel engineers still make

University of Manchester researchers made a pressure-sensitive paint that reacts to heat 25% less than the industry benchmark. Wind tunnel teams testing above Mach 5 still have to correct for temperature, only by a smaller amount.

Blue glow from a gold molecule corrects the temperature error in its red pressure signal

University of Manchester chemists made a gold molecule that glows red for pressure and temperature and blue for temperature alone. Comparing the two colors lets wind-tunnel paint correct its own pressure readings without a separate temperature sensor.
