Composite materials

Composite: Mixture of two or more distinct materials

Electronic Materials

MEMS (electronic materials)• MEMS: Microelectromechanical systems.

Miniature devices

Nanomaterials• Nanomaterials: Characteristic length < 100 nm

Examples: ceramics powder and grain size < 100 nm

Nanomaterials are harder and stronger than bulk materials.

Have biocompatible characteristics ( as in Zirconia)

Transistors and diodes are developed on a nanowire.
