Wireless Biomedical Sensing

Wireless biomedical sensing is a technique that measures physiological signals of humans or animals from a distance without a wire connection. Its basic components are sensor/transducer, transmitter, and receiver with an electromagnetic wave as the most widely adopted transmission medium. The theory of wireless communication with an enhanced biomedical aspect is presented. The current status and future trends of this field are also discussed.
