Embedded discrete passives technology for bandage-type medical sensors of E-healthcare system

E-healthcare utilizes the latest information and communication technology (ICT) in healthcare. It is viable by three major elements of a medical sensor, a gateway and a server. The medical sensor worn on users' or patients' body acquires such bio-signals as ECG (Electro Cardio Graphic), body temperature and blood oxygen saturation, and wireless transmits the signals to the gateway such as a cell phone. The bio-signal information is finally sent to the server at hospitals through cellular network and then reversely real-time diagnosis and treatment to the users or patients is made from doctors or nurses. Since users have to wear the medical sensor on their body during their everyday life, the sensors are required to be thin, small and flexible considering the users comfortableness. This study will explore embedded discrete passive technology, which enables thin and flexible bandagelike E-healthcare sensors.
