Description
Fanni Gu and co-authors build a heat sensor in 2025 that works only with light, no electric parts at the sensing tip. Such sensors suit places like fuel plants, where a spark could set off a blast. Past designs struggled to fit tight or harsh spaces.
The sensor threads a thin glass fiber into a steel tube, then coils the tube into a small spring. Heat stretches the spring, which changes the light path inside the fiber. A split-light setup reads that change as a temperature value. Tests from deep cold to warm heat showed small error and a fine step size, checked against a standard probe. The design may guide safer sensors for industry.
