Detailed Product Description
Product Name: Customized Piezo Ceramics

 
25X10X5 p4 Material Piezo Ceramic Element or Customized size
 
 
Piezoelectric ceramic materials are electromechanical transducers: They can convert mechanical energy into electrical energy and vice-versa.  Piezoelectric ceramic material from us are used in sensors, actuators, gas ignition and in power transducers for high-power ultrasonic applications.
 
 
 
Piezoelectric ceramic  Material are used to convert mechanical parameters, such as pressure and acceleration, into electrical parameters or, conversely, to convert electrical signals into mechanical movement or vibration.
 
In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers to convert electric voltages into vibrations or deformations.

PHYSICS ANSWERS

1. Reason to the existence of piezoelectricity?
The essential unit which is a rhomboid or cubic shaped cage made up of atoms exists in some atomic lattice structures. Inside the cell, the cage is responsible for holding single semi-mobile ion that has numerous quantum position states. By applying electric field or by distorting the cage (applied strain), the ions post state will consequently shift. The basis or transformation to internal electric field shifts from mechanical strain is provided by coupling between the cage and central ion.
 
2. How can poling and depoling in piezoceramic materials? Be explained?
The piezoceramics should undergo high electric field for a sometime for the alignment of randomly oriented micro-dipoles in their proper formulation since the chemical composition is not simply responsible for the piezoelectric property of ceramics. This is called “poling” due to alignment resulted from application of high voltage. a “dislodging stress” is exerted on the micro-dipoles due to the application of electric field in the opposite direction if tried. There is only temporary change in polarization if low level field are applied since it bounces back on removal. There is also partly degradation of the polarization along with partial loss of properties when medium fields are applied. Polarization in opposite direction will be resulted if high fields are applied.
 
3. Is there a possibility of using piezoceramic actuators at cryogenic temperatures?
The answer is yes. From down to zero degrees Kelvin, allpiezo actuators continue to function even though it may appear counter-intuitive. Since electric fields cannot be changed by temperature at all and the inter-atomic electric fields are the basis for the piezoelectric effect, the most common piezoceramics does decrease due to piezo coupling as temperature drops. Most importantly the motion of most materials drops to about one-seventh of that measured at room at liquid helium temperatures.
