Camera modules contain actuators to enhance image quality by moving optical components with a high level of precision. CML has designed, developed and licensed actuators to provide Autofocus (AF) and Optical Image Stabilisation (OIS) to a range of top tier manufacturers. Tens of millions of end devices have shipped with CML technology inside.
AF ensures the subject of the image is sharp. Almost all modern smartphones have at least one AF actuator. OIS is used to counteract shake a camera experiences whilst capturing images and is used mainly in premium handsets. See the effect of OIS to remove shake-induced blur in the graphic below.
As camera resolution continues to improve, image sensors increase in size making the lenses larger and heavier. Conventional actuators struggle to move them, but CML's SMA actuators provide ten times the force and are well-suited to address this trend. These actuators do not cause magnetic interference, allowing the close arrangement of additional camera modules as well as antenna and audio components. This enables high packing density, minimising bezels and maximising battery capacity.
Haptic actuators allow users to interact with technology using the sense of touch. They fit below the surface of an electronic device providing a tactile sensation across a surface removing the need for protruding components such as mechanical buttons.
CML's SMA haptic actuator creates a range of realistic local tactile sensations. CML's technical expertise designed an actuator capable of producing high force movement in a miniature form factor, providing a satisfying localised tactile sensation. The ability to control the movement of SMA wires and generate precise waveforms allows the feel of the button to be varied according to user preferences and applications.
SMA haptic technology boasts minimal power consumption compared to competing solutions and runs on a low drive voltage for a simple, easy to integrate solution.
CML has developed a 3D sensing technology which outperforms solutions found inside the world’s leading smartphones today.
Our technology not only increases the spatial resolution of existing solutions, but also the depth range of operation, and with a lower overall power budget.
3D sensing has a very broad range of potential applications, including smartphones, robotics, augmented and virtual reality, industrial machine vision, and many more.
