About CML

Cambridge Mechatronics Limited (CML) is a multi-disciplinary company, developing camera module solutions utilising our cutting-edge shape memory alloy (SMA) technology. Our technology is shipping in top tier flagship smartphones, as well as inside drones, wearable devices, and other consumer products.

We have approximately 700 granted and pending patents based around our platform technology, which allows the control, positioning and movement of smart materials with high precision.

CML’s SMA wire is thinner than the width of a human hair and can be positioned with the accuracy of the wavelength of light. CML is the only company in the world to master and control these materials with such exceptional accuracy.

The work environment at CML is stimulating and exciting, as we are involved throughout the entire product development process from inception through to mass production, which provides a real sense of achievement for our employees.
