Mentoring 2 Smart Ring & Mental Battery Service
Mentoring 2 is a ring-type wearable designed for everyday daytime use. By continuously sensing biometric signals, it helps people notice subtle shifts in their emotional and energetic rhythm throughout the day.
Paired with the Mental Battery app, these signals are translated into intuitive visualizations that gently reveal one’s current state and support moments of pause and rest—without judgment or instruction.
Rather than reacting to numbers, the experience encourages awareness, acceptance, and a reconnection with one’s own pace.
DesignDesigned by NAOTO FUKASAWA DESIGN, Mentoring 2 adopts a signet-ring silhouette that blends naturally into both professional and everyday life.The refined, compact form is intended to feel familiar and unobtrusive—quietly accompanying the wearer across different moments and lifestyles. The ring is available in seven sizes.
TechnologyMentoring 2 measures biometric signals using four types of sensors:
・Electrodermal activity (EDA)
・Photoplethysmography (PPG)
・Peripheral temperature
・Motion data (accelerometer and gyroscope)
Using these inputs, MENTAGRAPH’s proprietary algorithm visualizes continuous emotional and energetic trends that are difficult to perceive through momentary self-awareness alone.
Biometric data is transmitted from the ring to the app at three-minute intervals, allowing users to stay gently attuned to changes in their condition as they unfold.
