Design secrets of ground-breaking fitness tracker

The design company behind an innovative breath tracking wearable has spoken about the development process of the first-of-its-kind device.

Known as Calibre, the device features a suite of gas and pressure sensors hosted in a tiny, portable, wireless module that clips to a face piece

With the device, users can track dozens of real-time metabolic and respiratory biometrics, including real-time data on airflow composition.

Its co-designers, design firm Design 1st, said it is the world's first wearable that continually measures breath volume and composition, compared to most wearable fitness trackers that primarily measure motion or heart rate.

Design 1st said they were approached by Calibre Biometrics to help co-design the wearable, which collects data from multiple gas sensors to measure the composition and flow of inhaled and exhaled air.

According to Design 1st, a key challenge was to determine human acceptance for wearable.

To do this they had to develop a device that was comfortable to wear, aesthetically appealing and engineered for precision and long-term use, as well as efficient mass production.

"With Calibre, Design 1st had the opportunity to incorporate extensive early market and user research and continuous testing to successfully de-risk from possible design or engineering challenges down the road, given the uniqueness of the project," said Kevin Bailey, president and CEO at Design 1st. “We're excited to have partnered with Calibre Biometrics to deliver a wearable that's truly the first of its kind.”
