Assisted Living System Architecture Based on Bluetooth low Energy and Wearable Sensors

摘要

The design of wearable sensors and development of novel wireless radio protocols drive advances in the assisted living technology which is a promising approach in terms of future domestic healthcare. In this paper we propose the system architecture for vital signs monitoring in home conditions. The prototype device is based on the microcontroller supporting Bluetooth Low Energy which may be used for medical data transfer in assisted living applications. We developed a respiration rate sensor and thermometer pickup to provide basic measurements of physiological signals. We tested a range of proposed wireless system in urban conditions. The temperature and respiration rate was then recorded to verify the system operation. We measured the power consumption to evaluate the low energy performance of the device which is vital aspect of the telemedical wearable system.
