University of Minnesota's Michael McAlpine and David Pearson said the 3D-printing process is relatively low-cost and could someday provide easy, quick access to the device without the expensive fabrication processes of traditional devices.

A three-dimensionally (3D) printed wearable device developed by researchers at the University of Minnesota Twin Cities features an ultraviolet and visible light detector that could be placed on the skin to correlate light exposure with symptom flare ups in people with lupus.

The device is comprised of multiple layers of electrodes and optical filters printed on a biocompatible silicone base.

Integrated with a custom-built portable console, the device provides continuous monitoring and real-time feedback.

Said University of Minnesota's Michael McAlpine, "The light is converted to electrical signals to measure it, which in the future can then be correlated with the patient's symptoms flare ups."
