Since the Flexible field effect transistor (F-FET) is the building block of any sophisticated electronic circuit, particularly in the area of wearable electronics and biomedical sensors, it has drawn a lot of attention recently. It is usually fabricated using stretchable semiconductors over polymeric substrates. This paper displays a brief overview of the current fabrication techniques of the F-FET, specifically in terms of the type of substrates and nano semiconductor technologies. As for the applications, flexible devices such as graphene, carbon nanotubes, and nanoparticles seem to be a candidate for future flexible devices due to their excitant electronic and stretchable characteristics.
