GEMRING

GEMRING is designed to help users understand what their health data means in everyday life beyond occasional health checks. Continuous wearing allows changes in the body to be recorded over time, giving users a more complete view of their everyday condition instead of relying on isolated measurements. Clearer feedback and practical guidance make health awareness easier to maintain as part of daily life. The concept extends Jagat’s idea of connection towards a closer understanding of oneself.

GEMRING integrates its sensing hardware into a screenless, one-piece ring weighing about 3.7 g. Its rounded profile and jewellery-like proportions give the device a simple, discreet presence on the hand during work, exercise and rest. The uninterrupted outer surface keeps the appearance clean, while the compact form supports continuous wear throughout the day. Inner diameters from 17.9 to 23.0 mm provide multiple size options while maintaining a consistent visual character across the series.

During daily wear, the ring continuously records heart rate, HRV, blood oxygen, sleep, skin temperature, activity and drinking-related behaviour, building a continuous picture of the user’s physical condition.
Location, phone status, images and connected IoT devices add information about the surrounding life context, giving the physiological record a clearer background.
AI connects these data sources and translates the combined record into understandable states such as body energy, sleep and fatigue, then provides corresponding suggestions to help users interpret changes and adjust their daily routines.

GEMRING places much of its ongoing development in software and AI algorithms. New analytical capabilities can be introduced through updates while the same ring remains in use, allowing the hardware to stay relevant as the service develops. Its rechargeable power system also avoids the routine use of disposable batteries, reducing battery waste during regular use.
