The Field Effect Transistor (FET) is today the basic element of Very Large ScaIe Integrated (VLSI) digital systems. FETs are also used in analog circuits for high frequency (microwave) applications. Different types of FETs are the Metal Oxide Semiconductor Field Effect Transistors (MOSFETs), the MEtal Semiconductor Field Effect Transistors (MESFETs) and the MOdulation Doped Field Effect Transis...

Graphene field-effect transistors are able to successfully monitor glucose in urine samples, showing their potential towards the fabrication of point-of-care testing devices.

It is very important to monitor pH values. In this paper, we fabricated an all-solid-state AlGaN/GaN-based ion-sensitive heterostructure field effect transistor (ISHFET) sensor microprobe. The microprobe could facilitate measurement of was by packaging the chip into a 21 G medical needle. performance integrated evaluated in range 4–9.18. A sensitivity 143.57 µA/pH can be achieved using with wid...
