There has been a mix of bemusement and intrigue this week as Prince Harry appeared alongside Meghan Markle on their tour of Australia wearing a mysterious black ring.
As uncovered by a number of newspapers today it is actually an Oura smart ring, but how does it work?
As revealed by Cypress Semiconductor Corp at the Consumer Electronics Show in Las Vegas in January, the Oura smart ring has been developed with Cypress' PSoC 6 BLE microcontroller (MCU) at it’s core.
The industry's lowest power, most flexible dual-core MCU has built-in Bluetooth Low Energy (BLE) wireless connectivity and its architecture enables Oura users (including Prince Harry) to track their sleep, recovery and daily activities for up to seven days with a single charge.
Leveraging its ultra-low power 40- nanometer process, low-power design techniques and a dual-core Arm® Cortex®- M4 and Cortex-M0+ architecture, the PSoC 6 MCU enables the new Oura ring to achieve more than 3-times the battery life and 10-times the processing capacity of its predecessor, along with a 50-percent smaller form factor.
The PSoC 6 MCU's BLE connectivity allows users' data to seamlessly sync with the Oura app and Oura Cloud and supports Over the Air (OTA) firmware updates.
The Oura ring can also store data offline for up to six weeks with PSoC 6 MCU's integrated flash memory.
Speaking back in January, the vice president of Cypress’ MCU Business Unit John Weil said; "We defined the PSoC 6 MCU architecture to help Internet of Things designers deliver market-defining capabilities.”
"The Oura ring exemplifies our vision of innovation. We are thrilled to be working with an award-winning company such as Oura Health to help them turn their ideas into products."
RS Components and Cypress will be showcasing the Oura ring at Electronica 2018 in Munich in hall C5, stand 147.
