Technology Description

The technology is a 2-Dimensional Nano-positioner device with complete control electronic and computer interface. Nano-Positioners are being used in Photonics, MEMS, Semiconductor & Biomedical Industry, Microscopy etc. A number of two dimensional nano-positioners are available in market, but they are bulky (in most cases), complicated and expensive.

The available products are mainly based on two technologies:

• Piezoelectric actuators
  
• Servo motors

This technology is a new way to get nanometre resolution (<50 nanometre) motion in two dimensions by using 'bimorphs'. The device comes with a microcontroller based stand alone control unit. This unit has keys to control movement in 2-Dimensions; linear in X-Y and angular about z-axis. The control electronics has an option of computer interfacing and could be controlled from computer as well. Control unit requires house hold power supply.

Benefits

The device is compact, light weight and low cost. Underlying principle leaves enough scope of customized product design. All degrees of freedom in 2-Dimensions can be achieved; linear in X-Y and angular about z-axis. Travel length in centimetres with step size of 50 nanometres. Temperature range of operation is -271° C to 60° C. No mechanical access is required and the device can work in vacuum and high magnetic field. The device has no voltages 'ON' when not in operation; this eliminates unwanted addition of electrical and mechanical noise.
