Compact  3D Coil Receiver Antenna For EM Motion Tracking

A 60% smaller 3D coil receiver antenna meets miniaturized EM tracking needs, suitable for VR/AR, wearables, and automation, enhancing tracking and reliability in confined spaces.

Premo Group has launched the 3DCC03 series, the market’s smallest 3D coil receiver antenna. The company claims the series is 60% smaller than its predecessor. The series has been designed to cater to the increasing demand for the miniaturization of Electromagnetic (EM) motion tracking sensors. The series addresses three essential challenges in motion tracking integration within confined spaces. Its compact design is perfect for applications where space is constrained, such as VR/AR headsets, wearable devices, and industrial automation equipment. Equipped with three-axis receivers, the series can simultaneously track multiple small elements like fingers, pens, or small wearables, making it suitable for motion capture and gesture recognition applications. Additionally, the gold-finished pads ensure dependable electrical connection to the PCB circuit, adding value in applications where reliability is a key concern.

The series features an inventive design that includes three-axis receivers within a single small core, resulting in a significantly reduced size of just 4.2mm x 3.2mm x 3.5mm while ensuring excellent isotropy (identical sensitivity across the X, Y, and Z axes). The series operates at a working frequency of 20kHz and is precisely manufactured using magnet wire as fine as 18um. It incorporates six gold (Au) finished pads for connectivity and is qualified in accordance with stringent quality standards (MIL-STD 202), functioning within an operating temperature range of -40C to +85C.

Electromagnetic (EM) sensors offer several benefits over optical and inertial or mechanical tracking sensors, including greater freedom of movement. Unlike other sensor types, EM sensors don’t require a line of sight, allowing them to be utilized in situations where other sensors might be ineffective. They also offer stability over time, with no drift, leading to more accurate tracking data. Additionally, EM sensors exhibit lower latency, delivering more immediate tracking information. Their performance even extends to inside or through the human body, thanks to their large wavelength, a feature that sets them apart from other tracking technologies.
