A Multi Parameters Wearable Telemetric System for Cardio-Pulmonary Fitness of e-Health

We report a multi parameters cardio-pulmonary (CP) monitoring system with features of low power consumptions (30 mA, 3.3V), miniaturization (size 25 cm2), and wireless data communications (Frequency 96 MHz) for wearable applications in e-Health. Its target application is for the evaluation of fitness of CP during exercises. We use a miniature bi-directional hot-wire sensor for respiratory function, an optical sensor for saturated blood oxygen level or plethsymograph, and two surface electrodes for single lead electrocardiograph. The fitness indexes include blood oxygen level, ECG, and respiratory functions, which will be used for the quantitative evaluation of the level of physical activity
