University of Washington Develops Thermal Earring for Continuous Temperature Monitoring

The innovative wearable outperforms smartwatches in accuracy and can monitor stress, eating, exercise, and ovulation.

University of Washington researchers introduce the thermal earring, a smart wearable that continuously monitors earlobe temperature.
The thermal earring, resembling a small paperclip in size and weight, features a 28-day battery life and can be personalized with fashion designs.
In tests, the earring proved more accurate than smartwatches in sensing skin temperature during rest and showed potential in monitoring stress, eating, exercise, and ovulation.
The device utilizes Bluetooth advertising mode for efficient power use and enters deep sleep after transmitting temperature data to conserve energy.
Future iterations may include heart rate and activity monitoring, with potential for solar or kinetic energy powering.
