Experimental validation of a wave-height sensor based on a MEMS piezoresistive cantilever and a waterproof film

This paper presents a barometric pressure-sensing wave-height sensor that employs a microelectromechanical system piezoresistive cantilever, an air chamber, and a micromesh waterproof film. The developed sensor has a height resolution of less than 5 mm in the 0.01–10 Hz frequency band and a high tim...

Zusammenfassung:This paper presents a barometric pressure-sensing wave-height sensor that employs a microelectromechanical system piezoresistive cantilever, an air chamber, and a micromesh waterproof film. The developed sensor has a height resolution of less than 5 mm in the 0.01–10 Hz frequency band and a high time resolution with 100 Hz sampling rate. We conducted wave height measurements at sea using the developed sensor and compared its performance with that of a commercial global positioning system buoy-type wave-height sensor.
