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