Temperature ring / ring

This ring is designed for blind people. It can be used while preparing meals or searching for a hot drink. The temperature transducer inside the ring can sense the high temperature at a safe distance, and warn the wearer by gentle alarm and quivering. This can help blind people avoid burning themselves.

The ring may be worn on a finger. When the finger is close to some hot thing, the temperature transducer senses the sharp temperature changing and sends a signal to both buzzer and micro quiver motor which will give out sound and a gentle quivering as an alarm.
