Efficient and cost-effective communications in ubiquitous healthcare: Wireless sensors, devices and solutions
Résumé
Ubiquitous healthcare means healthcare anywhere anytime, a dream not realized in most parts of this world. On the other hand, the cost of healthcare is increasing and may become totally unaffordable in view of the aging population in many countries. Hence, the world is exploring the means to enhance the reach of healthcare at lower cost. The recent developments in wireless sensor devices and applications provide a glimmer of hope in tackling this gigantic problem through telehealthcare, where part of the healthcare can be performed remotely over information and communication networks. Thanks to the progress in communication and information processing technologies (sensors, biosensors, wire and wireless communication, web semantics, smart phones, game consoles, etc.), ubiquitous healthcare could soon be a reality. It is also envisioned that the convergence of disciplines such as information and communications technologies (ICT), biotechnologies, and nanotechnologies will accelerate the innovation in the field, and open up new opportunities for miniaturization and largescale production of efficient and affordable products in the future. Nevertheless, standardization will have an important role in ensuring interoperability between devices and information systems, a key factor for large-scale and cost-effective deployment of e-health systems.
