The continuous search for people welfare through various mechanisms, has led medicine to seek synergy with other disciplines, especially engineering, among many other developments allowing the application of new techniques to monitor patients through their own body signals.The application of new developments in areas such as electronics, informatics and communications, aims to facilitate significantly the process of acquisition of biomedical signals, in order to achieve a correct approach when developing diagnostic or medical monitoring, to optimize the required care process and sometimes to reduce the cost of such processes.In some specific situations it is desirable that the patient under monitoring does not lose his mobility by the wire connection to the device that captures any particular signal, since this state may interfere with the study.For example, in case you need to measure the heart effort of a p e r s o n t a k i n g a w a l k o r a s p r i n t .I t i s i n t h i s t y p e o f e n v i r o n m e n t w h e r e n e w I C T technologies such as Wireless Sensor Networks (WSN) can support the development of biomedical devices allowing the acquisition of various signals for subsequent monitoring and analysis in real time.Telemedicine also called e-health is everything related to electronic health data for monitoring, diagnosis or analysis for the treatment of patients in remote locations.Usually this includes the use of medical supplies, advanced communications technology, including videoconferencing systems (Enginnering in Medicine & Biology, 2003).Telemedicine systems can establish good and emerging technologies such as IEEE standards 802.11, 802.15 and 802.16, which these bases are characterized by the distribution networks for medical information, and provision for life-saving services.These systems have certain restrictions in the sense that when these wireless communications may be affected by a storm, or in conditions where the signal to transmit is not the most appropriate spots, then due to these problems, which solutions were sought resulted in great advances in wireless networking technologies providing vital routes for the restoration of services in telemedicine.The efficiency of telemedicine systems are widely affected by the design of systems, such as standardization, which in this case would not only rapid deployment, but also easy access for maintenance and renewal future systems that support care services.The constant study and monitoring of biomedical signals, has been an important tool in the development of new medical technology products.However, these over time begin to see that they are useful and important in industries that formerly had not been implemented www.intechopen.
