Research

My research is currently based around three areas:

• Piezoelectric Stick-Slip Actuators
  My main interest includes the design, testing and modelling of piezoelectric stick-slip actuators.

• Piezoelectricity
  Piezoelectricity is a property shown by certain classes of crystalline materials. When mechanical pressure is applied, the crystalline structure produces a charge proportional to the pressure. This charge can then be converted into a voltage using a charge amplifier. Conversely, when an electric field is applied the crystalline structure changes shape, producing dimensional changes in the material. The latter principle is the basis for electro mechanical actuators.

• Ultrasonic Motors
  I am also interested in Ultrasonic Motors which work above 20 kHz and are therefore inaudible to the human ear.

• Inchworm Motors
  My research interest also includes inchworm motors which are available from Burleigh.
