A one-port SAW in-liquid sensor platform: Design and fabrication
Paper i proceeding, 2017
SH-SAW In-liquid sensors have been explored extensively in recent decades. They propose an ability to work at higher frequencies, than the well-known QCM, with the aim to reduce the size and ease the integration in sensor arrays. So far SH-SAW liquid phase sensors are designed in two-port delay line configurations because of the need to protect the IDT from the conductive and dielectric loads from the liquid. A compact one-port resonant SH-SAW liquid sensor is yet to be developed as an alternative of QCM at high frequencies.
