The Mentoring 2 smart ring will finally be unveiled to the public on January 6th (local time) at Venetian Expo Halls A-D (booth location: 55433). If you're attending CES 2026, please stop by our booth and take a look at our latest smart ring, "Mentoring 2." We look forward to seeing you there.

■ Key points of the exhibit at CES 2026

Mentoring 2, a smart ring that visualizes mental fatigue
"Mentoring 2" visualizes Mental Battery levels (levels of mental fatigue) using a proprietary algorithm based on four types of sensors. The ring's stylish design, created by Naoto Fukasawa Design, a globally renowned designer, blends seamlessly into everyday life while providing innovative support for each individual's mental health. Going forward, the service will expand beyond corporate to include individuals, aiming to realize a new approach to mental health that integrates seamlessly into each individual's lifestyle.

‍Speedy Rest Eye Mask "Relaxonic Cover"
Guests can also try out the "Relaxonic Cover," a speedy resting eye mask equipped with ultra-high frequency and heat functions. Experience high-quality rest with deep relaxation around the eyes and ears thanks to the ultra-high frequency "Hypersonic" and heat functions.

Relaxing booth with a Japanese theme
We offer a relaxing and relaxing experience between exhibitions in a space with a Japanese motif and tatami mats.

Product Overview

"Mentoring 2" and "Mental Battery" Services

This is the world's first smart ring that continuously visualizes the fatigue and stress of workers, focusing on the time periods during the day.

Design
The project was handled by NAOTO FUKASAWA DESIGN, headed by world-renowned designer Naoto Fukasawa. The design is based on the shape of a signet ring. While fitting naturally into business settings, the universality of the design allows it to blend seamlessly into a variety of everyday lifestyles, making it a product design that can also be adapted to future developments in personal services.‍
Technology
・High-precision biometric data is measured using four sensors (EDA: electrodermal activity, PPG: pulse wave, TEMP: body temperature, and acceleration/angular velocity: behavioral estimation). A unique algorithm visualizes Mental Battery values (level of mental fatigue) from the measured data, revealing ongoing fatigue that could not be detected with conventional stress checks.
・The ring transmits biometric data to the app every three minutes, allowing users to monitor their stress levels in real time.

Relaxonic Cover Eye Mask

This eye mask uses ultra-high frequency and heat functions to help you achieve deep rest in a short amount of time.

Sound Technology・We have independently developed a sound source and speakers that contain ultra-high frequency "hypersonic" components in the 80 to 88 kHz range.
・The speakers are designed so that the Hypersonics reach not only the ears but also the skin around the ears, providing a deeper relaxation effect.
‍
Warming Function
Equipped with a heating function that gently warms the eye area at 40-42°C.
Design and Materials
Based on facial data from thousands of Asian people, the design is designed to fit snugly around the ears and eyes, and the cushioning material is luxurious.

Comment from Jun Adachi, CEO of MENTAGRAPH Inc.

JT's corporate R&D organization, "D-LAB," has been exploring ways to address the fluctuations in people's minds. The Mental Battery service and the new Mentoring 2 smart ring were born from this exploration and commercialized. By using technology to visualize the invisible state of mind, we hope to help users recognize their own weaknesses and strengths, creating opportunities for them to enrich their minds.

We are truly looking forward to unveiling "Mentoring 2" to everyone for the first time at CES, the cutting-edge technology exhibition, and to offering you a new resting experience through the "Relaxonic Cover."

We hope to receive honest feedback from visitors and engineers from around the world, and to be exposed to new perspectives and possibilities for collaboration. We hope to apply the encounters and learnings we make here to MENTAGRAPH's future challenges.
