Patent ID: 10624573

Abstract:
There is a sunscreen detection device for detecting a sunscreen product, the sunscreen detection device comprising: a substrate; a first light, disposed on the substrate and controllably coupled to a processor, controllable by the processor to emit light at a first light wavelength at the subject's skin when the sunscreen detection device is oriented to emit light on the subject's skin; a first light sensor circuit, disposed on the substrate and communicatively coupled to the processor, capable of sensing a percentage absorption of light by the subject's skin at the first light wavelength (% AbsAtWL1) and communicating the % AbsAtWL1 to the processor; a processor, configured to: cause the first light to emit light when the sunscreen detection device is oriented to emit light on the subject's skin; record the % AbsAtWL1 from the first light sensor; and assess a level of sunscreen protection based at least on the % AbsAtWL1.
