Researchers at Montana State University (MSU) in the US have developed TrialWear, a wearable electronic device aimed at improving the safety of clinical trial participants.

The invention by assistant professor Elizabeth Johnson of MSU’s Mark and Robyn Jones College of Nursing is a patch that bears a scannable code connecting to essential patient information for use in non-research medical settings.

The device is engineered to notify individuals through a text message to present the code to healthcare workers when they visit medical facilities.
