How it Works

🔍 How it works – temperature without a battery

Our rings can measure body temperature without a battery by using passive technology. This means the ring does not generate or store power on its own.

Inside the ring is a tiny temperature-sensitive material. When your body temperature changes, the material reacts in a subtle but measurable way. These changes can be read without electricity or charging.

The ring is only activated when it is scanned or read externally. In this process, your natural body heat acts as the signal instead of a battery. This allows the ring to function continuously without ever needing to be charged.

The result is a simple, reliable, and maintenance-free way to track temperature, designed to work seamlessly over time.
