Smart Earrings

Researchers from the University of Washington have developed Thermal Earring - a pair of wireless smart earrings that can monitor multiple health parameters of the user. The device, which is the size and weight of a small paperclip, can continuously operate for 28 days without charging. Equipped with a built-in antenna and Bluetooth module, the earrings transmit readings to a smartphone at specific intervals throughout the day, while going into sleep mode in-between.
