Premo launches smallest 3D coil receiver antenna for VR/AR

Premo Group, a provider of electromagnetic motion tracking sensing solutions, has unveiled the 3DCC03 series, said to be the smallest 3D coil receiver antenna on the market.

With a 60% smaller size than its direct predecessor, the 3DCC03 series it has been designed to meet the growing demand for miniaturisation of EM motion tracking sensors.

The 3DCC03 series incorporates three axes receivers in a single tiny core. This allows for an extremely reduced size of just 4.2 x 3.2 x 3.5 mm, while still maintaining excellent isotropy (same sensitivity in X, Y and Z axes). The 3DV03 series also features a working frequency of 20 kHz, 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 -40ºC to +85ºC.

The 3DCC03 series solves three key problems in the field of motion tracking:

Integration in tight spaces: The 3DCC03's small size makes it suitable 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 3DCC03's three axes receivers allow it to track multiple small elements simultaneously, such as fingers, pens, or small wearable devices. This makes it suitable for applications such as motion capture and gesture recognition.

Reliable connectivity: The 3DCC03's gold finish pads provide reliable electrical contact to the PCB circuit.

Compared to optical and inertial or mechanical tracking sensors, EM sensors have several advantages, including:

Freedom of movement: EM sensors do not require line of sight, so they can be used in applications where other types of sensors cannot.

Absence of drift: EM sensors do not drift over time, so they provide more accurate tracking data.

Reduced latency: EM sensors have lower latency than other types of sensors, so they provide more responsive tracking data.

Perform very well inside or through the human body due to its large wavelength.

The miniaturised design of the 3DCC03 opens a wide range of new applications for EM motion tracking, including: VR/AR, robotics, industrial automation, motion capture and wearable devices.
