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.

"Routinely we’ll evaluate a case and many of the questions that come up in regarding the investigation of abuse is the nature of the injury, how it happened, when it happened. And it got me looking into some of the science behind how do we study bruises and how do we know bruises," said Woodridge.

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.
