An apparatus and method for monitoring biometric parameters

摘要

A device for monitoring biometric parameters comprises: a light collector 3, configured to collect ambient light 13, provide the collected light 27 to a portion of skin 17 of a user and filters the collected light to increase the proportion of light within a selected range of wavelengths; a photodetector 5 enabling biometric parameters to be monitored by detecting changes in the light absorbed by the portion of skin 17; and an amplifier. The light collector may comprise a photoluminescent material to absorb light of a first wavelength and reemit light within selected ranges of wavelengths. The range of wavelengths reemitted may be used to monitor heart rate or blood oxygen levels. The light collector and photodetector may be positioned adjacent to the skin of the user where the user may wear the device. A supplementary light source may be provided which may comprise one or more light emitting diodes.
