WebA through-wafer etching scheme based on deep reactive-ion etching is developed to create the CMUT annulus. Immersion characterization reveals that the CMUT has a center frequency of 2.63 MHz, a -6-dB fractional bandwidth of 131%, and a receive sensitivity of 22.57 mV/kPa, compared with 2.34 MHz, 42%, and 4.28 mV/kPa of the piezoelectric probe. WebThe Sensor is based on excitation of a free acoustic mode description of an isolated transmitter CMUT, which in turn is coupled to the receiver CMUT via the fluid under inspection. The receiver CMUT picks up the impulse signal in time-domain, this signal resonates the receiver CMUT at a frequency which depends on the viscosity of the fluid.
