UW-developed smart earrings can monitor a person’s temperature

The temperature sensing earring is shown attached to a person’s ear. The portion touching the earlobe has a gemstone on it. Dangling a few centimeters below it is a small circular circuit board.

University of Washington researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user’s earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.
