Two-colour glowing molecule could make wind tunnel tests more accurate

Researchers have developed a single molecule capable of measuring both air pressure and temperature at the same time, overcoming a longstanding challenge in sensor technology. By emitting two different light signals, one affected by both pressure and temperature and another affected only by temperature, the molecule can automatically correct for temperature effects and provide more accurate pressure readings. Designed for use in specialist sensor paints, the breakthrough could help engineers capture more reliable pressure measurements from aircraft models in wind tunnels, even when temperature
