Elderly Gait Analysis and Assessment Based on Body Area Network.

As the nerve cell of the Internet of Things, WSN (wireless sensor network) have been the most important part of our life. Even more WBSN (wireless body sensor network) as one kind of WSN have been one part of our body. Sensor technology, Computer technology, wireless technology, semiconductor technology and so on all these development has made sensor network node so smaller, lighter and more multifunctional that can be dressed in portably. The sensor nodes can sample many of vital signals such as ECG, EEG, EKG, SPO2, body-temperature, Glucose, Heart Rate and so on, activities of daily living and gait information, environment information. All of information collected is transferred to extracorporeal data center. Based on the information collected something related to health can be analyzed.
