Abstract
A hydrogen sulfide sensor includes a substrate, a par of interdigitated electrodes disposed on the substrate, and a homogeneous polyaniline sensing film disposed on the pair of interdigitated electrodes and having electrical conductivity that depends upon a concentration of hydrogen sulfide. A method for detecting hydrogen sulfide includes for each sensor of a plurality of sensors: generating a signal if said sensor is exposed to a sample of hydrogen sulfide having density greater than or equal to a hydrogen sulfide detection threshold of said sensor, wherein the plurality of sensors has a respective plurality of hydrogen sulfide detection limits that span a detection range. A method for forming a hydrogen sulfide sensor includes dissolving a polyaniline polymer and a metal-chloride salt in an organic solvent to form a solution, and spin-coating the solution to form a homogeneous sensing film disposed on a pair of interdigitated electrodes disposed on a substrate.
