VERSION The piezoelectric element used, is the PZ 23 lead zirconate titanate element. .
You can leave this sounder out,if you don't need sound or worry about piezoelectric element destroying the FPGA board.
The PLZT element is a piezoelectric element and generates deformation by applied voltage.
The needle is given the SIN wave analog signal, and control is performed to make iteasy to insert the needle by vibrating using the piezoelectric element.
Piezoelectric element generates positive voltage when compressed and negative voltage when stretched.
By the piezomethod, it push ink using piezoelectric element to transform because an electric current flows.
The piezoelectric element expands or contracts depending on the direction of the potential when a potential difference is applied to the two terminals.
Transverse Wave Speaker" having a structure combining a piezoelectric element and a diaphragm is also introduced.
DESCRIPTION Conventionally, the piezoelectric element is used as the oscillator for buzzer and speaker, ultrasonic generator, positioning device, acceleration sensor and so on.
Recently, the application is expanding to the system controlling Piezoelectric element, Organic electroluminescence system, or MEMS.
In the ultrasonic motor, a piezoelectric element arranged in a ring formation generates ultrasonic vibrations in a metallic ring stator, and the vibration energy is used to rotate a metallic ring rotor that is attached to the stator.
In Scanning Probe Microscope(SPM), displacements of a stacked piezoelectric element are directly used for high resolution positioning.
When the driving voltage is applied to the piezoelectric element that has adhered to the chopper base in this state, the piezoelectric element extends or contracts in a longitudinal direction in this figure, and the electric field line blocking shutters at the end periodically open and close due to the flexure stress applied to the chopper.
