The first smart ring with life sensing capability
The term SOXAI originates from the Japanese idiom "no illness, no disaster" (meaning "healthy body"); Today's thriving SOXAI has set a lofty goal - to seamlessly integrate healthcare into daily life. So they launched Japan's first smart ring SOXAI RING 1 with life sensing capability. Due to the unsatisfactory performance of traditional smartwatches, the founder and CEO of SOXAI, Tatsuhiko Watanabe, has explored a path to track personal health status in a low-key and accessible manner, leveraging his profound professional expertise in optoelectronics and global perspective.
Challenge
Non invasive smart ring - Create a highly miniaturized ring that can continuously monitor key data for eight days with just one charge
■ Long wearing time - can ensure normal use even during daily activities such as bathing
Solution
A low-power sensor with excellent impact resistance and the ability to utilize edge AI functionality to perform various tasks
influence
■ Comfort - More people tend to use ring style devices to monitor key data
■ Precision - Monitoring accuracy can be improved through continuous data collection
■ Convenient - longer battery life and fewer charging times
Why is there an inseparable relationship between wearability and measurement accuracy
The success of SOXAI, founded in 2021, can be attributed to their understanding of a simple principle, which is that wearability and measurement accuracy are closely related. And rings, as an item that needs to be worn for a long time, can collect key data for users even when they are sleeping or taking a shower, effectively enhancing their own value.
Nowadays, wearable devices are rapidly sweeping the global healthcare market. Among them, smart rings are taking advantage of the situation and are winning the market share that was once monopolized by smartwatches. Compared to smartwatches, the advantages of small devices include being compact and lightweight, able to be worn all day, and convenient for measurement using photoplethysmography (PPG).

Smart watches are not suitable for continuously monitoring people's daily activities. However, SOXAI RING 1 can maximize the performance of STMicroelectronics sensors.
How edge AI brings more comfortable, precise, and convenient experiences
SOXAI has collaborated with multiple domestic and international universities and utilized STMicroelectronics' technology to complete the design, development, and manufacturing of SOXAI RING 1 in Japan. This ring can monitor various key data, including sleep cycle, heart rate, stress level, physical activity, and calorie expenditure, among others. The product weighs only 3 grams and only needs to be charged once to continuously collect user data for eight days.
What secrets are hidden behind such powerful performance? SOXAI RING 1 is equipped with a large number of health smart components, including STMicroelectronics' LSM6DSOX. This sensor not only has an accelerometer and gyroscope built-in, but also utilizes a unique machine learning kernel.

This ring can be used 24/7 for up to eight days after a single charge, even when taking a shower. In this way, the ring can collect more data, thereby improving the accuracy of monitoring results.
Only need to charge once to continuously monitor key data for eight days
One major advantage of this machine learning kernel is the ability to reduce power consumption by reducing the workload of microcontrollers, without the need to process raw output data from accelerometers and gyroscopes. Therefore, the amount of data processed by this microcontroller is only a small fraction of the previous model. This can at least extend the battery life of SOXAI RING 1 by 10 hours, thereby bringing a huge competitive advantage to the company when the product is launched. Finally, in order to meet the demand for long-term wear and ensure the durability and service life of the product, the company has added dust-proof and waterproof designs to SOXAI RING 1.
Tatsuhiko Watanabe, Founder and CEO of SOXAI
When we were developing SOXAI RING 1, STMicroelectronics launched the world's first sensor equipped with edge AI technology. Therefore, in order to improve the performance of the product, we quickly adopted this sensor. Compared with the first generation product, SOXAI RING 1 can extend battery life by at least 10 hours, which is a major innovation in the wearable technology field.
