An electronic device includes a first field effect transistor that includes a first gate electrode, a first drain electrode, and a first source electrode; a second field effect transistor that includes a second gate electrode, a second drain electrode, and a second source electrode, the first and second gate electrodes being at least one of electrically connected or integral, and the first and second source electrodes being at least one of electrically connected or integral; an input electrode electrically connected to the first and second gate electrodes; and an output electrode electrically connected to the first and second source electrodes. The first field effect transistor also includes a first semiconductor material. The second field effect transistor further also incudes a second semiconductor material. At least one of the first semiconductor material and second semiconductor material has a surface that can be exposed to a fluid and changes an electrical property thereof while being exposed to the fluid.
