We demonstrate the design, fabrication and use of a dual electrode PMUT(Piezoelectric Micromachined Ultrasound Transducer) integrated with amicrofluidic channel as a fluid density sensor in both static and dynamicdensity-change conditions. The dual electrode configuration makes the PMUTresonator a self-contained resonant peak-shift sensor and the microfluidicintegration makes this system a versatile fluid density sensing platform thatcan be used with extremely low volumes of fluids in various industrial andhealthcare applications. The density measurements carried out here underflowing fluid conditions demonstrate the potential of this system as areal-time fluid density monitoring system. We include results of densitymeasurements in the range of 1020 - 1090 kg/m3 that corresponds to the humanblood density variation generally due to the change in its hemoglobin content.The sensitivity of the sensor-26.3 Hz/(kg/m3)-is good enough to reliably detecteven 1% change in the hemoglobin content of the human blood. Thus, this systemcould potentially be used also as a hemoglobin measurement sensor in healthcareapplications.
