**5. Conclusions**

In this chapter, a mobile e-health-management system has been presented. This system integrates a wearable ring-type pulse monitoring sensor and a portable biosignal recorder with a smart phone. The ring-type pulse monitoring sensor can measure pulse and temperature, while the biosignal recorder can record electroencephalogram (EEG), electrocardiogram (ECG), and body 3-axis acceleration during daily lives. Based on these EEG, ECG, and acceleration data, several indices can be evaluated to estimate the user's physical activities. With the help of the mobile "exercise-333" health management mechanism developed on the smart phone, the user can monitor his/her own physiological data to practice the idea of "Prevention is better than cure," developing a healthier life style. The presented system, with the popularity and mobility of smart phones, effectively provides the needs for mobile health management.
