The smallest 3D coil receiver antenna for VR/AR launched

Premo Group has launched the 3DCC03 series, the smallest 3D coil receiver antenna on the market. With a 60% smaller size than its direct predecessor, the series has been created to fulfil the growing demand for the miniaturisation of EM motion tracking sensors.

The series provides an innovative design incorporating three axes receivers in a single tiny core. This provides for an extremely reduced size of only 4.2mm x 3.2mm x 3.5mm while maintaining excellent isotropy (same sensitivity in X, Y and Z axes). The 3DV03 series also offers a working frequency of 20kHz, accurate manufacturing using up to 18um magnet wire, connectivity using six gold (Au) finished pads, and qualification according to high-quality standards (MIL-STD 202). The operating temperature range is -40C to +85C.

The 3DCC03 series solves three key problems in motion tracking with integration in tight spaces: Its small size makes it excellent for integration into applications with limited space, such as VR/AR headsets, wearable devices, and industrial automation equipment. Simultaneous tracking of multiple small elements: The series' three axes receivers enable it to track numerous small elements simultaneously, such as fingers, pens, or small wearable devices. This makes it excellent for applications, including motion capture and gesture recognition. The gold finish pads supply reliable electrical contact to the PCB circuit. This makes it excellent for applications where reliability is critical.

EM sensors have several advantages, including freedom of movement, compared to optical and inertial or mechanical tracking sensors. The EM sensors do not need line of sight, so they can be employed in applications where other types of sensors cannot. The sensors do not drift over time, providing more accurate tracking data. The sensors have lower latency than others, supplying more responsive tracking data. They also perform well inside or through the human body due to their large wavelength.

The miniaturised design of the series opens an expansive range of new applications for EM motion tracking, including VR/AR, robotics, industrial automation, motion capture, and wearable devices.
