摘要： An influenza detector for detecting a targeted influenza virus and a surface acoustic wave (SAW) sensor for Influenza A virus detection in liquid are provided. The influenza detector includes a liquid environment, the surface acoustic wave (SAW) sensor and an influenza specific binding agent such as an antibody. The agent is immobilized on a surface of the SAW sensor for selectively capturing an analyte for the targeted influenza virus. The SAW sensor is in contact with the liquid environment and includes a substrate comprising a piezo-electric material for producing a surface acoustic wave signal in response to an applied electric field and an insulative layer formed on top of the substrate and having a functionalized surface formed thereon for selectively immobilizing the influenza specific binding agent, the functionalized surface being in contact with the liquid environment. The surface acoustic wave signal produced by the SAW sensor changes in response to the analyte for the targeted influenza virus being present in the liquid environment and being captured by the influenza specific binding agent immobilized on the functionalized surface of the insulative layer of the SAW sensor.

摘要： A fluid jet dispenser using at least two multilayer piezoelectric actuators is provided. The fluid jet dispenser includes a dispensing head and an electrical driver. The dispensing head includes at least two d31-mode multilayer piezoelectric actuators, a displacement magnifying element mechanically coupled to the d31-mode multilayer piezoelectric actuators, a piston, and a nozzle. More preferably, the two d31-mode multilayer piezoelectric actuators operate in an anti-phase condition. The electrical driver is electrically coupled to the d31-mode multilayer piezoelectric actuators for displacing the actuators in directions substantially perpendicular to polarization of piezoelectric layers in the d31-mode multilayer piezoelectric actuators in response to charging and discharging of the actuators by the electrical driver, to generate a fast movement of the piston to jet a pressurized fluid out of the nozzle of the dispensing head.
