MAXREFDES106#

MAXREFDES106# health system platform 4.0 is a chest patch reference design that performs vital sign monitoring (VSM). The system uses high sensitivity photoplethysmography (PPG), electrocardiogram (ECG), and bioimpedance (BioZ), Temperature biosensors and algorithms measure blood oxygenation (SpO2), heart rate (HR), respiration rate (RR), impedance cardiography (ICG), body impedance analysis (BIA), and skin/ambient temperatures. The vital signs data can be streamed through low-energy Bluetooth® to a PC graphical user interface (GUI) for demonstration, evaluation, and customized development.
