Brillar and Kyoto University Join Forces on Wearable Technology

In a groundbreaking collaboration, Brillar, a jewelry brand celebrating its eighth anniversary, has teamed up with Kyoto University to patent an innovative ear-cuff wearable device equipped with radar sensors. This unique invention integrates the expertise in radar sensing and signal processing cultivated by Professor Takuya Sakamoto's research team at Kyoto University with Brillar's deep understanding of aesthetics and wearability gained through years in the jewelry industry.

The Vision Behind the Device

The core mission of this newly patented technology is to allow continuous monitoring of vital signs such as respiration rate, heart rate, and blood pressure while simultaneously capturing full-body movements, including those of the head. By embedding various sensors and radar into a comfortable ear-cuff design, the device aims to achieve both high usability in daily life and innovative health monitoring capabilities.

Patent Application Details

• - Applicant: Brillar Inc. and Kyoto University
• - Filing Date: November 7, 2025
• - Inventors:

- Mitsutoshi Ohara, CEO of Brillar

- Takuya Sakamoto, Professor at Kyoto University

The patent's outline details the incorporation of sensors which are capable of detecting bodily signals and movements through the ear, making the device a unique entry in the emerging field of wellness technology.

Development Background: Integrating Design and Health

Recent times have seen a surge in the popularity of wearable devices like smartwatches and fitness rings, which serve essential roles in personal health care. However, users often express discomfort when wearing these devices for extended periods, citing issues like pressure on the skin and unsuitability for formal occasions.

Brillar, with its robust heritage in jewelry design, has tirelessly worked toward creating pieces that seamlessly blend into everyday wear. This patent is a natural extension of their goal to create “wellness jewelry,” allowing users to enjoy health monitoring benefits without sacrificing aesthetics. The unique aspect of this partnership lies in the ability to harmonize non-invasive sensing technology with beautiful design—resulting in a product that addresses both comfort and functionality.

Expected Applications

The radar-based ear-cuff device is envisioned to be utilized in numerous scenarios:

• - Continuous monitoring of vital health signs during daily activities
• - Self-care initiatives tailored for improved sleep quality
• - Collaboration with elderly care services to detect falls or dizziness.

Pitched as an integral part of one's daily attire, the ear-cuff device aspires to shift the narrative away from “wearing only when needed” towards a mindset that fosters consistent and natural usage as part of a refined personal style.

Future Prospects

With the patent application serving as a foundation, Brillar is set to explore the commercialization of the ear-cuff wearable device:

• - Development of prototypes and ongoing user testing to refine design and algorithms
• - Investigation into collaboration opportunities across medical, healthcare, fitness, and wellness sectors.

Through these steps, Brillar aims to innovate within the emerging category of “wellness jewelry,” working closely with Professor Sakamoto’s laboratory to enhance everyday health experiences through beautifully designed technology.

The Significance of the Patent

Professor Takuya Sakamoto commented on the importance of this invention, stating, ‘Accessories like ear-cuffs reflect the sensibilities of their wearers. By merging sensing technology with a natural form of adornment, we are creating a new experience that gently observes shifts in emotional and inner states while retaining personal expression.’ This innovative marriage of accessory and technology could redefine values in the jewelry and health care markets alike.
