SOXAI Begins Providing Proprietary Vital Sensing Technology Platform 'SOXAI OS™' to Sharp's First Smart Ring 'Kokorami Ring'

SOXAI Inc. (President and CEO, Tatsuhiko Watanabe; hereinafter 'SOXAI') announces the provision of its proprietary vital sensing technology platform 'SOXAI OS™' (Sokusai OS) to Sharp Corporation (Representative Executive Officer, Tetsuji Kawamura; hereinafter 'Sharp'). The first smart ring from Sharp, 'Kokorami Ring' <MH-R01>, incorporating this technology, will be released on Thursday, July 9, 2026.

Since its founding, SOXAI has accumulated expertise in sensor design, device firmware, biometric signal algorithms, and data analysis and visualization through the development of Japan's first smart ring, 'SOXAI RING'. This technology transfer marks SOXAI's initiative to expand its internally developed technology platform to partner companies, representing a significant step toward accelerating the societal implementation of vital sensing technology.

Key Points of This Release

・ SOXAI provides its proprietary technology platform 'SOXAI OS™', cultivated through its own smart ring development, to Sharp. The platform will be embedded as the core technology powering Sharp's first smart ring, 'Kokorami Ring'.

・ SOXAI will receive technical support from Sharp for the mass production of 'SOXAI RING 2', initiating a mutually beneficial collaboration between a startup and a major manufacturer, leveraging each other's strengths.

・ Moving forward, SOXAI will actively promote the licensing of SOXAI OS™ to partner companies. Centered on smart rings that seamlessly integrate into daily life and enable 24-hour high-precision vital measurement, SOXAI aims to expand the application scenarios for vital sensing technology.

Background of the Technology Provision

In recent years, growing interest in employee health management within corporations has been driven by the expansion of the Certified Health Management Excellent Enterprise system and the increasing adoption of well-being and human capital management practices. Additionally, with the progression of a super-aging society, the importance of preventive medicine and personal daily health management continues to rise.

However, for continuous daily acquisition of vital data, in addition to measurement accuracy, minimal wearing burden is crucial. While ring-type devices (smart rings) are gaining attention as wearables that can be naturally worn 24/7, including during sleep, their realization demands cross-domain development capabilities. This includes sensor design for extremely compact ring-shaped housings, device firmware to control communication and power consumption, high-precision biometric signal processing algorithms, and further integration of data analysis, visualization, and application connectivity.

In this context, SOXAI has consistently developed all these technological domains in-house through the self-development of its Japan-originated smart ring, 'SOXAI RING', systematizing its expertise into the technology platform 'SOXAI OS™'.

By collaborating with Sharp, a company with over 110 years of history, and commercializing this technology platform, SOXAI can deliver its innovations to a broader customer base.

About SOXAI OS™

'SOXAI OS™' is a technological foundation in the vital sensing domain, integrating sensor design, device firmware, biometric signal processing algorithms, and data flow from the SOXAI RING.

At its core are optical sensing technologies based on advanced expertise in optics, and miniaturized device design and manufacturing technologies. Since its founding in 2021, SOXAI has consistently advanced from fundamental research to prototyping and mass production, steadily accumulating expertise in optical design, implementation, and manufacturing. One key outcome of this accumulation is the proprietary photoplethysmography (PPG) sensor technology 'Deep Sensing™' (Patent No. 7655609), developed using spatially resolved spectroscopic multi-wavelength PPG technology.

Furthermore, through joint research and clinical studies with domestic and international universities and research institutions, including the University of Tokyo, SOXAI continuously evolves its high-precision biometric signal measurement technologies and proprietary analysis algorithms, supporting the entire process from vital data acquisition to analysis and visualization.

This technological foundation enables high-precision heart rate measurement, blood oxygen saturation measurement, sleep stage estimation, and more, and is provided as a vital sensing platform capable of integration into third-party products.

Value Creation Through Mutual Collaboration

In this initiative, while SOXAI provides Sharp with the core sensing technology 'SOXAI OS™' for smart rings, SOXAI will simultaneously receive technical support from Sharp for the mass production of 'SOXAI RING 2'. This marks the beginning of a collaboration that combines the startup's technological development capabilities with the large manufacturer's expertise in manufacturing, quality control, and mass production. This partnership aims to deliver higher value from both companies and contribute to the activation of the smart ring market.

Overview of Sharp's 'Kokorami Ring'

Sharp's 'Kokorami Ring', to be released on July 9, is the company's first smart ring. Leveraging SOXAI OS™ technology, it enables 24-hour measurement of health data such as heart rate, blood oxygen levels, and sleep.
