Abimorph actuator is composed of two thin panels of ceramic elements bonded together with a flexible metallic panel as it's central electrode. By wiring these two elements in such a way as to make one elongate and the other contract by applying voltage, inflection deviation occurs conforming to the waveform of the applied voltage.
There are other factors to be considered too along with this specifications like:
Mechanical quality factor etc.
There are three major limitations to the bimorph piezoelectric actuator.
The Shaping of the electrodes and laminate can be in several forms
Each shape will have a different response time and force when a specific voltage is applied.
A typical SoC consists of:
As low vibration amplitude cannot be neglected in any design. With the help of some reconfigurable SoC, vibration estimation in the can be done easily. This system can be used for rapid adaptation to any function, guaranteeing both low cost and short design times.
