The earring is equipped with a dual-sensor system that will stay magnetically clipped to the earlobe to take the temperature of the wearer, while the second dangling sensor will take ambient room temperature readings for reference. The earring has an integrated antenna and Bluetooth Low Energy (LE) module to communicate directly with the user’s device for tracking, and is rated to provide up to 28 days of use per charge. The earring was prototyped by Shirley (Qiuyue) Xue and Yujia (Nancy) Liu at the University of Washington.
Xue commented on the Thermal Earring saying, “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.”
