Microsystems (otherwise known as MicroElectroMechanical Systems, MEMS) are mechanical devices that are fabricated on a micrometre scale using techniques more commonly associated with the semiconductor industry for the fabrication of microelectronic devices. They can be classified as either passive devices (e.g. cantilevers, beams) or actuators (e.g. electrostatic drives, thermal expansion actuators) or sensors (e.g. gyroscopes, pressure sensors) and the worldwide market for these devices has expanded greatly in recent years. This course will introduce both the processing methods by which these devices are manufactured and the properties of the materials which are employed, including traditional silicon-based technology and new materials, such as diamond-like carbon, polymers and biological thin films.
Case studies will be used with particular reference to one sensing and one actuating application to exemplify how materials and fabrication processes are integrated
