ABSTRACT
Modern telemedicine, telehealth, and mobile health systems are almost all dependent on the appropriately designed and implemented sensors, wireless instruments and instrumentation systems, and networks for gathering the relevant information and transmitting it to target databases for further processing. This chapter describes such technologies and gives examples as they are applied in biomedicine. A wireless instrument communicates with the external world by radio-frequency (RF). Thus, a wireless interface must be provided for allowing RF communications. The power consumption of a wireless instrument limits its working time, especially when functioning with batteries. A wireless sensor network can be considered a network of wireless instruments whose sensorial nodes are the wireless instruments themselves. Biomedical applications have a high potential for using wireless instruments. The increased application potential of wireless sensors networks in several fields of human society resulted in the need for their standardization as well as for their wide acceptance.
