What is it about?
The air pressure sensors used for aerodynamic testing of high-speed trains are currently based on microelectro mechanical systems (MEMS), but which are sometimes restricted in actual. Herein, a flexible ultrathin air pressure sensor for aerodynamic testing of high-speed trains is reported, this sensor is based on a sensing material of carbon fiber beams and a sealed microchamber structure.

Why is it important?
Air pressure sensors play a crucial role in aerodynamic tests on high-speed trains, especially when the aerodynamic problems become more significant when the speed of high-speed trains increases. The air pressure sensors used for aerodynamic testing of high-speed trains are currently based on microelectromechanical systems (MEMS), which are thick, difficult to adjust linear range, and easily damaged by overloading force and water, thus cannot satisfy all-weather train aerodynamic monitoring. Therefore, we have developed a waterproof, anti-impacted, and ultrathin air pressure sensor for aerodynamic tests on the high-speed trains. Furthermore, this sensor presents great promise toward the aerodynamic tests on highspeed trains by the successful application in real-time train surface pressure monitoring.
