“…As pointed out by Luck and Agba [3], the operating condition of the cylindrical piezoelectric actuator can be considered isothermal. This assumption is suitable when the piezoelectric tube takes a slowly varying or quasi-static motion so that its electric field and isothermal conditions are close to dE = dT ≈ 0.…”

The rapid prototyping industry is growing dramatically because of its high potential to reduce product design and prototyping cycles. One of the recent technologies in this field is 3D printing using conventional ink jet technology. In order to maximize the capability of this process, it is required to understand the operating mechanism and drop formation process. The current work focuses on the mechanism of a piezoelectric cylindrical actuator and the hydrodynamic characteristics inside a print head in order to achieve more realistic boundary conditions for the numerical simulation of the drop formation process. Linearised Navier-Stokes equations for Newtonian fluid flow are solved analytically for the pump section with a constant radius and for the nozzle section with a tapering angle. Results from the developed solutions are input to Flow 3D and it is observed that analytical pressure histories show better agreement with numerical results than axial velocity histories. The presented analytic model can be used for fully further drop formation simulation as an upstream pressure boundary within an acceptable tolerance.

“…Therefore, piezoelectric elements are commonly chosen due to fast response, small size, lack of electromagnetic interference, large thrust, fast reaction rate, and high precision. Piezoelectric elements therefore find common application in positioning systems [1,2,3], atomic force microscopy (AFM) [4] and in inertia motors. Because the elongation of piezoelectric elements is short, scientists design flexure structures [5,6,7,8,9] or inertial sliders [10,11] to increase the displacement indirectly.…”

The design of a dual-mode inertia motor involves an actuator that can generate translational and rotational motion without connecting the actuators serially. Traditionally, translational or rotational actuators should be stacked serially to have multi-axis degrees-of-freedom. The experimental results of this study display performance characteristics such as linearity, resolution, velocity and the most excellent operating frequency.

“…Recently, for a small range of motion, flexure systems seem to be able to satisfy many positioning requirements. An example is a piezoelectric actuator [1][2][3] which can realize 10 nm resolution with 1 µm travel. On the other hand, larger range positioners, such as the steppers in IC-lithography, are based on devices with ball-screws or linear motors [4,5].…”
