Latest Patents

Ulisses holds 1 patent for his invention titled "Sensor system and method for gamma radiation dose measurement." This patent describes a printed radiation sensor that includes a substrate, an interdigitated electrode, and a conductive polymeric film. The interdigitated electrode consists of a first electrode with multiple digits and a second electrode with a plurality of digits. The conductive polymeric film is a blend of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and polyvinyl alcohol (PVA). The PEDOT:PSS serves as an electrically conductive medium, while the PVA provides ductility and stability to the sensor. Upon exposure to radiation, the PVA crosslinks within the material matrix, forming a semi-interpenetrating polymer network (SIPN) with the PEDOT:PSS, which enhances the stability and impedance reading of the sensor.
