Device Created to Determine the Age of Bruises

Students and professors at the University of Arizona have designed a device to measure the age of bruises. The idea for the technology came from Dr. Dale Woodridge while working on child abuse cases.

Woodridge contacted UA’s engineering department. A group of six engineering students collaborated to design a device and test it a few months later. Woodridge said the device could be used to determine when abuse has occurred. After more testing, he hopes to distribute the portable, non-invasive device to medical facilities.
