Abstract

A method of photoplethysmography includes processing a signal based on at least one signal from at least one sensor arranged to capture light from a living subject to extract information on a characteristic of a periodic biological phenomenon. At least one of the signals from at least one sensor is obtained via sensing radiation as to a peak in an absorption spectrum of water.
