A wearable biosensing system via sheet medium communication

Recently, wearable biomedical sensor networks which sense bio-information such as electrocardiogram and brain wave have attracted high attention. Typically, it is assumed that the biomedical sensors are communicated with base station via wire or wireless. However, in the case of wired communication, the cables for data and power transmissions are cumbersome in the biomedical sensor network. Even in the case of wireless communication, biomedical sensors have to be equipped with battery, which replacement also gets into mess. Furthermore, the wireless signals from sensor modules may interfere to biomedical signals or other communication devices. To conquest the above problems, in this paper we propose a wearable biosensing system via sheet medium communication, which performs both data and power transmission for the real time unrestrained measurement of biomedical signal in our daily life.
