Abstract
A wearable UV sensor includes a UV pass filter; a UV phosphor material; and a visible light sensing device, wherein the UV sensor is configured to receive light including visible light and UV light, wherein the UV pass filter directs the UV light to the UV phosphor material and the UV phosphor material fluoresces visible light in proportion to the UV light from the UV pass filter, and the visible light sensing device measures the visible light fluorescing from the UV phosphor material to determine the amount of the UV light entering the sensor, which correlates to the UV exposure of a subject wearing the UV sensor.
