A 3D printed light-sensing medical device is placed directly on the skin and gives real-time feedback to correlate light exposure with disease flareups. The device could help millions of people worldwide with lupus and other light-sensitive diseases by providing access to more personalized treatments and information to determine what causes their symptoms.
The 3D printed device with a flexible UV-visible light detector can be placed on the skin. The device is integrated with a custom-built portable console to continuously monitor and correlate light exposure to symptoms.
The device consists of multiple layers of materials printed on a biocompatible silicone base. The layers include electrodes and optical filters. Filters could be changed out depending on the wavelength of light that needs to be assessed. The research team also used zinc oxide to collect the ultraviolet (UV) light and convert it to electrical signals. The device is mounted on the skin and a custom-built console is attached to capture and store the data.
