The piezoelectric ceramic wafer is electrical devices with a simple
structure and light, with high sensitivity, no magnetic field
spread without spillover, copper wire and magnets, low power
consumption, less cost, easy mass production and the advantages of
widely used. Suitable for ultrasonic and acoustic wave transmitting
and receiving, piezoelectric ceramics is relatively large area and
can also be used to detect pressure and vibration. The working
principle is to use the reversible piezoelectric effect, applied
voltage in the audio, and voice.
APPLICATION ANSWER
1.The frequency limit of apiezoceramic sheet and some properties?
Usually the frequency limits of applications are ascertained
through the resonances involved with the transducer design and its
size and shape. For a piezoceramic sheet, there is no limit for
inherent frequency. A sheet of PSI-5A material which is 2.85″
square, .0075″ thick has planar dilatation mode of about 14 KHz and
of 13 MHz of thickness mode vibration in the neighborhood. Limiting
factors can arise such as the resistive heating of electrodes when
considerable current is gathered at large surface area parts during
ultrasonic frequencies.
CHNOLOGY 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 power
