Researchers on the Tokyo College of Science, Iwate College, and Mitsubishi Heavy Industries have developed a brand new sensor which may assist enhance equipment used within the power era and transport sectors — by flexing throughout curved surfaces, like fan blades, to measure high-speed airflow precisely.
“Sensing the shear stress and its course on curved surfaces, the place stream separation simply happens, has been tough to realize particularly with out utilizing a novel method,” explains Masahiro Motosuke, professor on the Tokyo College of Science, of the issue his crew sought to resolve.

The crew’s proposed answer: a microelectromechanical system (MEMS) sensor, constructed on a mushy substrate, which is skinny and versatile sufficient to be utilized to curved surfaces. Integrating a micro-heater and 6 temperature sensors organized in an array round it, the sensor is able to measuring wall shear stress and stream angle — and by adjusting the place of the circuits surrounding the sensor, disruption to the measured stream is saved to a minimal.
The researchers are hopeful that the sensor may discover a use for bettering the effectivity of industrial-scale fluid equipment utilized in power era and transportation — although it wants further work first. “Though this sensor is designed for quick airflows, we’re at the moment growing sensors that measure liquid stream and may be connected to people primarily based on the identical precept,” Motosuke explains. “Such skinny and versatile stream sensors can open up many potentialities.”
The crew’s work has been printed below open-access phrases within the journal Micromachines following its presentation on the twelfth Symposium on Micro-Nano Science and Know-how.
