The Piezo-Electric effect is when an electrical voltage induces a movement in certain solid crystals, ceramics, bone, etc. It also is the reverse effect, where movement or strain of that material induces an electrical voltage.
The small piezo disc in the back of your alarm watch is one example, generating a tone from an AC signal. Another example of the reverse effect is the starter on your gas grill, generating thousands of volts from the snap action of the impact from the trigger hammer.

What are pressure transducers used for?
== The most common use of piezoelectric transducers is in sonography. That's sonar. And medical sonography, the so-called ultrasound, represents the broadest application of the technology. The ultrasound is in use in medical imaging right now in a number of places around the world. It is very common for pregnant women to undergo the proceedure. They are also used in speakers and the like, in applications as a "force gauge" and as a method of control for scanning tunneling microscopy. They are also used in basic physics research such as the study of so-called Fermi surfaces where ultrasound is passed through a crystalline sample in a magnetic field. == Piezoelectric transducers are used to measure dynamic events. The events a piezoelectric tranducer can measure is typically relative to a force. Such as vibration (dynamic g forces), force / impact (dynamic in nature), and pressure (once again dynamic). Piezoelectric transducers do not measure true static events. Such as your weight when stepping on a scale. What a piezoelectric will measure is the impact of your body stepping on the scale and any changes in force applied to the scale. Some examples of use would be in manufacturing where a press is being used rapidly. Piezoelectric pressure sensors are used to measure the dynamic events of pressure. Such as the turbulance in a pipe or combustion pressures in an engine. Piezoelectric accelerometers measure g forces dynamically. This is generically considered vibration. This measurement can detect bearing faults in a motor from its 'vibration' or the structural integrity of an aircraft based on its vibration and response to the forces put into the structure. A material that generates an electric charge when mechanically deformed. Conversely, when an external electric field is applied to piezoelectric materials they mechanically deform. This above effect is called Piezoelectric effect Every day use of this phenomena is used in load cells. Load cells are used on large weigh scales for trucks and large bin scales where materials need to be weighed. The signals from the cells are calibrated to compensate for the weight of the scale so that the scale can be zeroed out. The cell signal because it is very small is sent to an amplifier head where is can be read by the operator in units of weight. The head unit can be set to read in metric or imperial weights.

What is diode reverse current?
the current which has negative value n passes through the diode is called as diode reverse current
What are the release dates for Reverse Serendipity - 2013?

How to generate power from piezoelectricity?
mainly Piezoelectric crystal is a transducer which convert mechanical energy to electrical energy.piezoelectricity material generate power, when we compress or extended its shape.means that when we change in dimension of material then the voltage produced between atoms of material by which power generate.
Is piezoelectric effect renewable?
yes
Are there any materials that undergo strong contraction when an electric current is introduced?
Yes, all piezoelectric materials exhibit the reverse piezoelectric effect. A piezoelectric material is one that generates an electric field or electric potential in response to applied mechanical stress. Therefore, in the reverse case, passing an electric current through the material or an electric potential across the material, will cause it to contract or elongate, depending on the direction of the current. One of the best example of this is lead zirconate titanate which will contract/elongate up to about 0.1% of the original dimensions.
What type of sensors are used on a 2002 Chrysler 300m?
There are potentiometers, resistors, hall effect switches, piezoelectric,
Why is quartz used in piezoelectric transducer?
Quartz is used in piezoelectric transducers because of potential for high voltage input and acoustic power. Quartz is a piezoelectric crystal and when it is mechanically strained or deformed by stress, electric charges appear on some surfaces. When the strain is reversed, the polarity of the charges reverse. This allows vibration of quartz crystals to be transformed into electric pulses.
How do you pronounce piezoelectric crystal?
Like this: (piezoelectric-crystal)
What is reverse effect in Yu-Gi-Oh?
A 'reverse effect' is the Japanese OCG term for what the English TCG calls a 'Flip Effect'.
Do tumbled quartz have piezoelectric properties?
Yes, all quartz has piezoelectric properties, whether it has been tumbled or not. However, in natural quartz, were optical twinning (equally distributed left and right quartz forms inside the material) is very common, the piezoelectric effect is not strong. That is the main reason why only synthetic quartz is being used by manufacturers, where twinning is almost absent.
What happens when piezoelectric crystals are kept in water?
Many piezoelectric crystals can be used in water with no issues.

yes
What is the cost of a piezoelectric crystal?
The vast majority of devices that use piezoelectric crystals (piezoelectric buzzers, fish finders, atomic force microscopes, etc.) use crystals of lead zirconate titanate (PZT). The crystal oscillator in a computer or digital clock uses the piezoelectric effect, but it is usually made of pure quartz (silicon dioxide). Many different crystals and other materials exhibit the piezoelectric effect, including quartz crystals, cane sugar, and bone.
