Wireless, Wearable Sensors-on-a-Chip Provide Precise Dosimetry at Multiple Wavelengths
EVANSTON, Ill., Dec. 11, 2018 — A wearable, battery-free sensor has been developed that can measure and monitor exposure to light across multiple wavelengths, from the UV to the VIS to the IR regions. The device, created by researchers at Northwestern University, can record up to three wavelengths at one time. The sensor features a system-on-a-chip design that allows wireless, smartphone-based access to an individual’s sensor-read solar exposure data.
