A survey of internet of things technologies and projects for healthcare services

IoT has been shown as a big potential for qualifying and improving healthcare services; such as monitoring at anytime and anyplace. These services acquire various bio-signals using different sensors, including electroencephalogram (EEG), electrocardiogram (ECG), electrical signal of the heart, electromyogram (EMG), electrical signal of muscles, Respiratory Rate (RR), and body motion. The collected information from these sensors can be processed, stored, or broadcast to a remote device (e.g. Cloud server). This paper provides an overview of the main medical sensors in IoT and a review of the current state-of-the-art of IoT projects, and technologies required for healthcare services. The paper specifically, focuses on the using of IoT technologies in the healthcare area nowadays. A conclusion regarding the current stage of development and open issues are presented.
