Shape Design Optimization of Unimorph Piezoelectric Cantilever Energy Harvester
The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...

متن کاملUnimorph piezoelectric deformable mirrors for space telescopes
We have developed, manufactured and tested a unimorph deformable mirror for space applications based on piezoelectric actuation. The mirror was designed for the correction of low-order Zernike modes with a stroke of several tens of micrometers over a clear aperture of 50 mm. It was successfully tested in thermal vacuum, underwent lifetime tests, and was exposed to random vibrations, sinusoidal ...
متن کاملOptimal Design of a Shape Memory Alloy Actuator for Microgrippers
In this paper, a modular microactuator based on shape memory alloy (SMA) actuation to drive the joints of a microgripper is described. Its design is a combination of two SMA actuators installed on the links of a special mechanism : one of them drives the rotation of the joint and the other one produces the necessary force to manipulate objects. An accurate model of the thermo-mechanical behavio...
متن کاملSimultaneous liquid viscosity and density determination with piezoelectric unimorph cantilevers
We have examined both experimentally and theoretically a piezoelectric unimorph cantilever as a liquid viscosity-and-density sensor. The fabricated piezoelectric unimorph consisted of a PbO•ZrO2•TiO2 ~PZT! layer on a thin stainless-steel plate. In addition to a driving electrode, a sensing electrode was placed on top of the PZT layer, permitting the direct measurement of the resonance frequency...
