Piezoelectric materials have been integrated with silicon microelectromechanical systems (MEMS) in both microsensor and microactuator applications. Some recent and emerging applications of piezoelectric MEMS are acoustic emission microsensors, vibration monitors, molecular recognition biosensors, precision positioners, micropumps, and linear stepper motors. - See more at: http://www.chacha.com/question/how-are-piezoelectric-materials-that-contain-silicon-used-in-science-and-industry#sthash.EpLIkFTw.dpuf
Look at some bricks or bathroom tiles, or at the porcelain enamel around the burner plates of a stove. You'll probably see small breaks in their surfaces. These breaks are evidence of one disadvantage of some ceramics: they are so rigid that they crack. One advantage is that they have strength. These ceramics contain silicon or aluminum, which can form small, rigid structures that bond together when water is removed.
By redesigning some portion of it to make it function properly.
TIG welding uses tungsten electrodes. Some electrodes also contain Thorium some also contain Zirconiun some are pure Tungsten. Each has its own applications.
Cell phones and computers as well as many other electronic devices.
Some items in a house that probably contain manganese include the kitchen sink and appliances made of stainless steel. Other items include batteries, loose change, and beverage cans.

Palladium is found in many everyday items, but you would probably not recognize it. One of the largest uses for this metal is in your car, more specifically in the catalytic converter. It is also a component of some electronics and jewelry.
Pennies (copper-plated zinc), objects made of brass (brass is an alloy of copper and zinc), and wires and cables that carry electricity and/or electronic signals.
