Great question: A piezoelectric material such as quartz might a very long time, but they do age. But for applications where absolute frequency stability is needed, other methods are used. See: http://en.wikipedia.org/wiki/Crystal_oscillator
The applications of piezo transducers are Proxmity Sensing, Nondestructive Evaluation, Fluid Flow Movement, Fluid Level Detection, and Solid/Liquid Separation. And sounders.
any wood that would last for a long time and that wont have a rough suface
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.
oscillator frequency is different.crystal working piezo electric effect
It is the same piezo electric effect, the vibrations caused by the sound waves are converted into corresponding electrical signals.
When piezoelectricity material is squeezed, it produces electricity. This is the esseantial idea about piezo materials.

A piezo-electric device generates electricity when mechanical stress or pressure is applied to it, causing a displacement of positive and negative charges within the material. This displacement of charges creates an electric potential difference, which can be harnessed to generate electricity.
Leather is the most durable material for a hat. It is thick and last a long time.
the piezo-eletric property of a crystal is the principle of quartz clock
A piezo pickup is the type of pickup most commonly used in acoustic-electric instruments. This type of pickup is normally placed in or near the bridge of the instrument thus making it a piezo bridge.
Calf skin is the most common material used for making cowboy boots. And as long as you take care of them, such as using a water protectant, they should last a long time.
A piezo is just a manual, mechanical type of module. In order to work as an ignition the piezo module will need to be wired to an electrode which will spark when the piezo module is pressed or cranked. An ignition system is an assembly of parts and the piezo is like a spark generator for an ignition that does not use batteries or electricity. Pressing or turning the piezo module will send electricity to the electrode which should be mounted where gas emits from the burner so the electrode sparking will ignite gas as the gas leaves the burner.
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.
There are several piezo crystals in the injector in order to achieve the required needle or valve lift. When an electric current is applied piezo crystals, they expand or contract. Since piezo elements are lighter, they respond quicker. This lets the injector valve switch five times more quickly to meter the fuel and control the injection curve more precisely.
Use wood material because wood is hard and it will last a long time. You can get some information from some websites to help you. Choose the wood cabinet so it can last.
A durable object or material that has a long lifespan such as steel, diamonds, or granite.
