Nano-Composite Piezoelectric Material

Abstract
This method will allow for the construction of high quality capacitors at low process temperatures for thick-film and circuit board manufacturing. Additionally this concept has possible applications in microelectromechanical system ("MEMS") devices manufacturing. Piezoelectric materials with high dielectric constants and combinations of various dielectric constant materials will allow for a nearly infinite variation of permitivity. This concept can also be applied to radio frequency devices such as cell phones.

Potential commercial uses and users:
Piezoelectric devices and capacitors for high frequency applications. Possible applications in MEM’s manufacturing.

Advantages:
The advantage created by this material and the corresponding polarization method would be to allow elimination of the high temperature >700 C step required in the present methods of producing piezoelectric films. Current technology requires the use of Sol-Gels and/or high temperature fired paste materials. The lower temperatures allow for the piezoelectric material to be applied at the end of the process on devices on which the metal has already been deposited.
