Abstract	In this paper, we present a suspended Single-Walled Carbon Nanotube (SWNT) based pH sensor utilizing a low temperature Dielectrophoretic (DEP) assembly process on a flexible parylene-C substrate. Parylene-C, a light weight, flexible and inert material, is compatible with many microfabrication processes. Furthermore, utilizing parylene-C as a flexible substrate, one can readily create a suspended microplatform utilizing an O2 plasma etch process. Suspended nanobridges have larger exposed surface areas and may potentially have enhanced sensitivity for sensing applications. Fabricating these structures on a thin (10μm) parylene-C substrate allows their utilization as flexible devices or in wearable sensor applications. We have successfully assembled suspended SWNT nanobridges across a spacing of 4μm. The electrical characterization results from the assembled SWNTs yield ohmic behavior with a measured two-terminal resistance of ~17KΩ. Furthermore, the conductometric measurements of the SWNT sensors have demonstrated that corresponding to an increase in pH value, the resistance of SWNTs has decreased due to the $OH^{-}$ group that attached on to the wall of the SWNTs and changed the electrical properties of the SWNTs. These novel suspended nanostructures can be used as potential candidates in nanosensor applications.
