The MOTHER Bracelet incorporates 'Thermoelectric Power Generation Technology' that was originally discovered by Estonian physicist Thomas Seebeck in 1821. After two centuries of research and advancements, it has been integrated into the MOTHER Bracelet. What sets the MOTHER Bracelet apart is its ability to recharge autonomously while you wear it, requiring just a 1℃ temperature difference in its environment. This revolutionary technology eliminates the need to take the device off for recharging, making the MOTHER Bracelet a game-changer in wearable technology.
