Video: A small bicycle handlebar sensor can help map a region’s riskiest bike routes

A black sensor sits on a wood table.

A UW-led team has developed a system, called ProxiCycle, that logs when a passing car comes too close to a cyclist (four feet or less). A small, inexpensive sensor plugs into bicycle handlebars and tracks the passes, sending them to the rider’s phone. The team tested the system for two months with 15 cyclists in Seattle and found a significant correlation between the locations of close passes and other indicators of poor safety, such as collisions.

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.
