Quartz crystal in quartz watches work on the principle?
Piezo-electric Effect
How can piezoelectric materials generate electricity from human footsteps?
Just place a piezo electric crystal in your shoe then due to alternate change of your feet causes mechanical stress and strain .Inverse piezo electric effect states that when stress and strain is given along mechanical axes it creates electricity along electrical axes.Thus piezo electric crystal converts mechanical energy to electrical energy.
Do you have to wind a quartz movement watch?
Many analogue watches nowadays use what's called a piezo-electric crystal to generate the energy required to function. In essence a piezo-electric crystal will generate an electric current when it is deformed, which can be achieved simply by applying a force to it (such as the one generated by the movement of your arm when you're wearing the watch). Recently, Nokia patented the first self-charging mobile phone, which uses the same principles in order to charge itself.
A piezo-electric device generates electricity when?
The unit of 'power' is the
What is the principle used in ultrasonic interferometer?
Inverse piezo-electric effect.
Quartz crystal in quartz watches work on the principle?
Piezo-electric Effect
What does piezo-electronic effect mean?
Piezo electric effect says that- "If you applied mechanical vibration on the surface of crystal than the voltage will generate on the another surface and vice versa is also true."it is called piezo electric effect.
What is the difference between crystal and local oscillator?
oscillator frequency is different.crystal working piezo electric effect

Which principle is used in a piezo-eletric property of a crystal?
the piezo-eletric property of a crystal is the principle of quartz clock
Can anything convert mechanical energy into light energy?
When mechanical pressure is applied to a specially prepared piezo-electric crystal it generates electro-magnetic energy that can be detected in the form of both light and heat. An example: the kind of gas-lighter that you "squeeze" contains a piezo-electric crystal. When you squeeze the handle it puts enough mechanical pressure on the crystal to produce the electricity necessary to produce a spark.
What is the working principle of crystal microphone?
It is the same piezo electric effect, the vibrations caused by the sound waves are converted into corresponding electrical signals.

For aquartz cristal of length 0.05mcalculate the fundamental frequency of oscillation in a piezo-electric oscillator if the velocity of longitudinal waves in the crystal is 5.5 x 1000 ms?
0.181 hertz. Are you sure about it being 1000 milliseconds? That is one second. Crystal is spelled crystal.
Why piezo crystal oscillator used?
Piezo-electric quartz crystals are used to define the frequency in a crystal-controlled oscillator. Quartz is a hard material that tends to oscillate mechanically at a high frequency (up to about 20 MHz) when maintained by the maintaining amplifier. The signal produced is far more stable and predictable than an L-C oscillator, especially when the crystal is placed in a dedicated oven with a controlled temperature.
What is the principle of quartz clock?
Piezo electric property
Can you convert the kinetic energy of a cricket ball into electricity?
Not particularly well. And there isn't that much energy in it anyhow. But sure, if it hits a piezo-electric crystal, there'll be a short spike of electricity.
