1. A biosensor comprising:
a flexible substrate; and
at least one field effect transistor assembly comprising a pair of flexible field effect transistors deposited onto the flexible substrate, each pair of flexible field effect transistors including:
a first electrode assembly including a first source electrode, a first drain electrode, and a first metal oxide channel, the first metal oxide channel contacting the first source electrode and the first drain electrode;
a second electrode assembly including a second source electrode, a second drain electrode, and a second metal oxide channel, the second metal oxide channel contacting the second source electrode and the second drain electrode; and
a malleable gate electrode deposited onto the flexible substrate, the malleable gate electrode interposed between the first electrode assembly and the second electrode assembly.
