Abstract: A method and system for measuring personal health, the method comprising detecting a photoplethysmograph (PPG) wave, the PPG wave generated based on a combination of infra-red and red lights, transmitting the PPG wave to a server, the server processing the PPG wave to infer biometric statistics based on machine learned correlations generated from a training set of PPG waves and biometric data, receiving the biometric statistics from the server, and generating display data based on the biometric statistics.

Abstract: A wearable personal healthcare device for measuring personal health is provided that is configured to detect a photoplethysmograph (PPG) wave generated by infra-red, green, or red lights emitted from the device, the personal healthcare device. The device includes an outward facing face, a lateral side, and a bottom side, wherein the bottom side faces a user's skin, a plurality of electrical contact sensors, wherein a first of the plurality of sensors is located on one of the top face, lateral side, and bottom side, and a second of the plurality of sensors is located on one of the top face and lateral side of the personal health care device. The first and second sensors are configured to complete a circuit therebetween when a user contacts the first sensor with a first surface of the user's skin and contacts the second sensor with the first or a second surface of the user's skin.
