University of Washington researchers have developed Thermal Earring, a wearable device capable of continuously monitoring a user’s earlobe temperature. Six users test the earring ion a study and found that it outperformed a smartwatch at sensing skin temperature during periods of rest.
The paperclip-sized prototype boasts a 28-day battery life and consists of a magnetic clip that attaches one temperature sensor to a wearer’s ear, while a second one dangles about 1-inch below it for estimating room temperature. This earring can also be personalized with various fashion designs made of resin or with a gemstone, all without affecting its accuracy.

Current wearables like Apple Watch and Fitbit have temperature sensors, but they provide only an average temperature for the day, and their temperature readings from wrists and hands are too noisy to track ovulation. So we wanted to explore unique applications for the earring, especially applications that might be attractive to women and anyone who cares about fashion,” said (Shirley) Xue, a UW doctoral student in the Paul G. Allen School of Computer Science & Engineering.
