Elder problem becomes civilization topic that country can?t ignore. Population develops a vast market, under popularizing the national attention. It is no longer one-way consumption in the social cost, and becomes a vast market offering community service. Various types of looking after this interdependent market direction of the equipment is developed rapidly. The researchers make great strides in the research and development of wireless network (WLAN) ,due to the popularization of WLAN. In this paper, we proposed a research to orientate the subject by detecting the power of radio wave. Then we adding the idea of e-health care to achieve an objective in remote control. The focus of our research was advancing the stability when retrieving the paper of radio-wave by ameliorating design of TAG. We combine the relevant physiological signal detecting devices with the TAG system made by ourself to achieve the applications of orientating the subject and e-health care.
