Abstract
An apparatus for measuring vital signs and various states of health using the underlying concept of Photoplethysmography (PPG). This apparatus comprises one or more light source(s) and one or more detector(s) configured to measure transmitted and/or reflected light within the digits such as a finger or toe, but can also be applied to other soft tissue elements. The apparatus comprises a means to enhance signal quality, control the volume of interrogated tissue and minimize motion artifact. The apparatus comprises a power source. The apparatus may further comprise at least one processor to receive information from the detector and process measured variations in light intensity. This information may be transmitted wirelessly through technology such as Bluetooth. The apparatus may also comprise a system utilizing inductive charging (“wireless charging”).
