Sensor system and method for gamma radiation dose measurement

Abstract

A printed radiation sensor that includes a substrate, an interdigitated electrode, and a conductive polymeric film. The interdigitated electrode including a first electrode with a plurality of first electrode digits and a second electrode with a plurality of second electrode digits. The interdigitated electrode disposed on the substrate. The conductive polymeric film including a blend of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and polyvinyl alcohol (PVA). The PEDOT:PSS is configured to provide an electrically conductive medium. The PVA is configured to provide ductility and stability of the printed radiation sensor. Upon radiation exposure, the PVA is further configured to crosslink within a material matrix of the printed radiation sensor militating against the recombination of chain scission by forming a semi-interpenetrating polymer network (SIPN) with the PEDOT:PSS to provide an enhanced and stable impedance reading.
