WBAN: WBAN is a network of tiny wireless sensors that are wearable or implanted in the human body for monitoring of the vital organs and providing feedback to the medical personnel or the user. The wireless sensors transmits the data from human body to its home base station. Since this data is real-time it can be transmitted to clinic, hospital, laboratories etc.

WBAN offers services in applications in the area of remote health monitoring, home/health care, medicine, multimedia, sports and many others.

The main advantage in WBAN is that the patient doesn’t have to stay in bed, but can move freely across the room and even leave the hospital for a while. This improves the quality of life for the patient and reduces hospital costs. The latest international standard for WBAN is the IEEE 802.15.6 standard.

A typical WBAN requires vital sign monitoring sensors, motion detectors (through accelerometers) to help identify the location of the monitored individual and some form of communication, to transmit vital sign and motion readings to medical practitioners. A typical body area network kit will consist of sensors, a Processor, a transceiver and a battery.

WBAN is used in following instruments:

• ECG for monitoring heart activity.
• EMG for monitoring patient muscle activity.
• Movement sensors.
• EEG for monitoring electrical activity of brain.
• Blood pressure sensor fir monitoring blood pressure.
