The stronger mechanical wave beam generated by the multiple input-IDT layers on the thin film (1 μm) Aluminum Nitride (AlN), consists of different-phase acoustic waves that can travel through a liquid medium. In contrast to the whole signal leaking into liquid medium as in typical SAW devices, the signal obtained at the receiver of the M-SAW device only has a decline in the Rayleigh component. The experimental results show that it is possible to interact with the liquid medium placed on the surface and extract information about the liquid volume based on the phase change. Phase shifts of -16.35°, -11.23°, -4.84°, and -0.86° are obtained for different volumes of demi-water after 10 seconds, 2, 4 and 5 minutes of vaporization, respectively. date: 2016-01-01 date_type: published official_url: http://ieeexplore.ieee.org/xpl/mostRecentIssue.jsp?punumber=7411154 full_text_status: none pres_type: paper pagerange: 475-478 event_title: MEMS: the 2016 IEEE International Conference on Micro Electro Mechanical Systems event_location: Shanghai, China event_dates: 24-28 Januaray 2016 event_type: conference refereed: TRUE related_url_url: http://ieeexplore.ieee.org/xpl/mostRecentIssue.jsp?punumber=7411154 citation: Bui, Thu Hang and Bruno, Morana and Tom, Scholtes and Chu, Duc Trinh and Pasqualina, Sarro (2016) A novel mixing surface acoustic wave device for liquid sensing applications.
