Abstract
A system for determining the hydration status of an individual utilizes a light sources and a photodetectors to extract a plethysmographic waveform from an individual and applies feature extraction to extract features from said plethysmographic waveform from which the hydration status of the individual can be inferred or calculated. The system of preferably housed in a wearable housing.
Claims26
A system for determining the hydration status of an individual comprising:
- a. one or more light sources;
- b. one or more photodetectors;
- and
- c. software, running on a computing platform, said software performing the functions of:
- i. receiving data from said one or more photodetectors, said received data containing a plethysmographic waveform obtained from said individual;
- ii. performing a feature extraction on said plethysmographic waveform to extract features indicative of the overall hydration status of said individual;
- and
- iii. interpreting said extracted features and providing feedback to said individual regarding said hydration status.
The system of claim 10 wherein said frequency spectrum is obtained by using a Fast Fourier Transform algorithm.
