In this paper, the method of electric analog synthesis is applied to design a piezo-electro-mechanical arch able show capacity multimodal damping. An electric-analog circuit designed by using finite number lumped elements representing equivalent curved beam. Spatial and frequency coherence conditions are proven be verified for modes damped: in fact, lumped-element can damp only vibration modes....

Atomic force microscopy typically relies on high-resolution high-bandwidth cantilever deflection measurements based control for imaging and estimating sample topography and properties. More precisely, in amplitude-modulation atomic force microscopy (AM-AFM), the control effort that regulates deflection amplitude is used as an estimate of sample topography; similarly, contact-mode AFM uses regul...

The aim of our work is to design a touch screen for displaying vibrotactile haptic feedback to the user via piezo patches attached to its surface. One of the challenges in the design is the selection of appropriate boundary conditions and the piezo configurations (location and orientation) on the screen for achieving optimum performance within the limits of human haptic perception. To investiga...

The piezo-phototronic effect is about the enhanced separation, transport, and recombination of the photogenerated carriers using the piezoelectric polarization charges present in piezoelectric-semiconductor materials. Here, it is presented that the piezo-phototronic effect can be effectively applied to improve the relative conversion efficiency of a flexible solar cell based on n-ZnO/p-SnS core...

Conventionally, intracytoplasmic sperm injection (ICSI) in the mouse is conducted with piezo-drills that use a droplet of mercury for damping. The use of mercury causes concerns of toxicity and contamination. Although Fluorinert can be used as a substitute for mercury to reduce piezo-drill’s lateral vibration, the damping effect is not as satisfactory as mercury. In this work, a modified piezo-...

The mode shapes of piezoelectric metamaterials are tuned by manipulating spatially the electrical boundary conditions piezo-elements, in a desired and controlled manner, order to tailor wave propagation characteristics through these metamaterials. piezo-elements using inductive shunting networks. With appropriate tuning optimization spatial distribution conditions, it would be possible alter sh...
