At the University of Tennessee s Center for Environmental Biotechnology, researchers are developing wireless biosensors that can be used to monitor microbial contamination and radiation exposure in future manned space missions. The researchers are using bioluminescent biosensor organisms built directly onto wireless integrated circuits. They call them Bioluminescent Bioreporter Integrated Circuits (BBIC). Bioluminescent...

Wireless biosensors for implantable or wearable sensors will be discussed in this chapter. The biosensors incorporating electrical measurements such as electrochemical transduction mechanism [potentiometric, amperometric, and field-effect transistor (FET)] and electrical transduction mechanism (resistance, capacitance, and inductance)... 

A simplex telemetry system is employed for the transmission using straightforward modulation schemes such as amplitude modulation, on-off keying, amplitude-shift keying, and phase-shift keying [101-103]. Because the physiological signals vary slowly, such modulation schemes are preferable for miniaturized and low-power wireless biosensors. 

Recent progresses in micro- and nanotechnology have led to the design of implantable, swallowable, wearable, or portable wireless biosensors to continuously monitor and detect important physiological parameters. The miniaturization and integration of biosensors, readout circuits, embedded microcontrollers, and wireless transceivers on a single chip have opened the way for new possibilities in medical applications.
