Miniaturized wireless monitor for long-term monitoring of newborns

Wireless infant monitoring system is a small-size wearable sensor platform. There is a growing trend to simplify the measuring methods to allow a real-time monitoring of the vital signals in home environment. Most of these devices have cables, are quite large in size that may disturb infant´s everyday life and need continuous supervising from parent. In this paper we propose a monitoring system that detects the most important vital signals of baby and transmits results over wireless link to the control device that could be any smart-phone. The system is capable of measuring blood oxygen level, heart rate, respiration rate, body temperature, body posture and legs activity. Combining all of these raw signals it is possible to use this system in different, possible life-threatening situations during long-term monitoring. Compared to other similar solutions it has small dimensions, low weight, increased reliability of measuring photoplethysmography signal and extended battery life because of the usage of Bluetooth Smart wireless protocol.
