The most powerful inertial sensor in its class, powered by Vicon

Engineered to capture the highest quality data


Higher fidelity measurement, three times faster data download speed, and real-time analysis – in the field and in water – Vicon’s Blue Trident is our newest life sciences wearable.

The next generation of our market-leading Inertial Measurement Unit (IMU), Blue Trident is lightweight, easy to use, flexible and reliable.

From elite to grassroots sports, the improved, form-fitting wearable IMU sensor can capture the highest load activities and provide immediate real-time athlete tracking and sports performance analysis in the field. It also benefits from being fully waterproof (IP68), making it suitable for all-weather capture, underwater treadmills and swimming.

IMUs are changing the game of sports performance analysis

In our latest article, we explain how motion capture is well-established as an essential tool, not only for sports biomechanics research, but also for sports injury rehabilitation and athlete recovery, training, and sports performance analysis at all levels, including running gait analysis and sport movement analysis.

The article takes a look at the role that wearable sports technology, such as inertial measurement units (IMUs), are playing in measuring athlete performance and the reasons why we’ll soon see Inertial Sensor Units in sport reach the tipping point to wide-spread adoption.

“Many movements made at high speed or involving the highest peak forces, such as changes of direction, sudden decelerations, landing and even sprinting, can lead to sensor clipping and loss of data. Having high g capability with the new Blue Trident, Inertial Sensor allows us to quantify and thereby gain a better understanding of these movements, improving insight into the preparation required for our athletes.”

“We are investigating the suitability of Vicon’s next generation sensors for a range of sports applications from cricket illegal action detection to injury prevention in junior cricket fast bowlers, specifically for monitoring shoulder, trunk and pelvis rotations. We are also evaluating how sports like AFL and soccer might adopt and use this higher specification sensor. What we have seen so far is very exciting.”

Jacqueline Alderson
Assistant Professor, University of Western Australia

“I believe that real time feedback must become the new normal as Inertial Sensor technology continues to evolve. Being able to understand performance as it happens, and subsequently make changes throughout a session if required, significantly upgrades our ability to care for our athletes.”

  • Waterproof

    IP68 rated and tested for submersion up to a maximum depth of 1.5 metres for up to 30 minutes – good for all-weather capture, underwater treadmills, swimming.

    Because we love to go above and beyond, we’ve also tested the sensor at depths far exceeding this.  We’ve used Blue Trident when submersed at depths of up to three metres for one hour.

  • Performance

    Better measurement performance and reliability with the dual sensors, so saturation drop off is avoided and users can capture even the highest peaks of activity – very useful for high-load activities such as cricket.
