Wireless Sensor Network In Medical Applications

Published:2010/8/26 19:24:00 Author:Michelle From:SeekIC

Wireless sensor network is a kind of technology that integrates several advanced technologies including sensor, embedded computing, modern network and the wireless communication technologies. There is a wide applied space for this promising industry. With the development of modern technology, the WSN will have a profound influence on ares of medical practise.

With its advanced predominance such as low price, convenience, speediness and instant, wireless sensor network have a wide usage in applications of medical researching, ICU rooms and daily care, thus made it a hot spot in medical area. For example, placed on the body of patient, mini sensor can have the remote detect of physical parameters such as blood pressure, heart beat, and finally collect all these information to the monitoring room to analyse, process and feedback. Besides, it is very helpful for doctors to have a clear knowledge about their patients by investigating data in the electric database. Above all, the WSN technology provides a brand new method for medical supervision in the future.

However, there are some difficulties that it is facing with respect to technological side. Technically, for the body parameters are almost weak and are hard to detect, special parts must be added to the system ,thus the cost will be raised. Besides, there also exists some challenges when put it into practical use. First is the data security. For the WSN system will susceptible to attacks and information of patients needs to be kept secret, it will have high standards to establish a perfect system. Second is the data integration.

Wireless sensor network in the future will be more intelligent, minimum and much lower power dissipation. It is the main trend for both home and abroad to establish wards and community supervision system with intelligent functions. Related chip is:1S2092.
