FRQ

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.

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.

2.Is there any truth to piezo transducers being used as static and dynamic force sensors?

Due to charge leakage the Piezo transducers cannot be used for static force measurements. For transient force measurements they can be applied successfully for only0.1 second.

3.The expected life of piezoelectric material?
There are no tests yet that can determine the “fatigue life”. Our facility has had an operational piezo fan since 1982. Such calculations must involve voltages and mounting.

4.How does temperature effectpiezoceramic transducers?
The pyroelectric properties of piezoceramic are responsible for the appearance of voltage through the any piezo transducer electrodes due to temperature changes. Almost each and every property of piezoceramics is affected by temperature. There exists no general manner regarding it. In accordance to your experiment and calculations, the dependence must be looked upon in that context.
