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.
 

 

PIEZO TECHNOLOGY ANSWERS

1.What is the process of eliminating vibration through piezoceramics?
The process of vibration cancellation can be achieved through attaching two piezoceramic sheets to the outer surface of the object. They should be close to the point (in a beam) where undesired bending needs to be controlled.The first sheet is used to measure the strain on the surface. The data from a strain sensor is put into a smart box. This gadget controls the power amplifier which consequently drives second sheet.As a result, the mechanically induced movement from second sheet produces vibrations into the structure, which counter the other vibrations.
 
2.Is there a possibility of Piezo technology replacing magnetic technology anytime in the future?
The possibility of Piezo technology replacing magnetic technology is not possible. Magnetic technology is based on force without physical contact. On the other hand, Piezo technology is purely derived from forces having direct contact from bodies.For instance, Piezo actuators have the capability of making all solenoids obsolete. However, they are heavier which is why it is highly improbably that magnetic technology will be forgotten because of Piezo technology.The main interest in Piezo actuators is because of the solenoids ability to work on less powe
