Zusammenfassung:An apparatus and a method of determining fluid properties by using a micro-machined suspended plate. The plate is suspended by a plurality of springs and the plate is in contact with the fluid. The power to move the plate and the phase angle between the driving frequency and the actual frequency that the plate moves changes as the plate is moved while in contact with the fluid. The device can measure clotting time, stiffness, damping ration, velocity, and viscosity of the fluid by comparison with standards.
