The present disclosure relates, according to some embodiments, to a wearable UV sensor for detecting a dose of an electromagnetic radiation, the wearable UV sensor comprising: (a) a polymer substrate comprising at least one polymer and at least one UV radiation exposure indicator; and (b) an adhesive, wherein exposure of the wearable UV sensor to the dose of the electromagnetic radiation produces a photochromic change in the polymer substrate. The present disclosure also relates to a method for determining a magnitude of a dose of UV radiation exposure, the method comprising: providing a wearable UV sensor comprising a polymer substrate, a UV radiation exposure indicator, and optionally an adhesive layer; exposing the wearable UV sensor to at least one dose of an electromagnetic radiation to form an irradiated wearable UV sensor, wherein the exposing results in a photochromic change by the wearable UV sensor; and determining the magnitude of the at least one dose of electromagnetic radiation.
