Study of High Electron Mobility Transistor for Biological Sensors

In this chapter, we emphasize on High Electron Mobility Transistors for assistive medical technology. Our focus is on the application of HEMT-based biosensors for the detection of different biomolecules. In this paper, we have discussed five different types of HEMT-based biosensors. The system of biosensor is comprised of three parts—detector, transducer, and amplifier. The detector recognizes the suitable analyte, the transducer converts the biological signal to a kind of a signal that can be easily measured, and the amplifier amplifies the signal, so that it could be visualized in a suitable format. This paper will help researchers to have an idea about HEMT-based biosensors at single place, which will help them to develop upcoming modern biosensors.
