Title: Katherine Shelton and Hydrogen Sulfide Sensing

Introduction

Katherine Shelton is an inventor associated with Lebanon, New Hampshire, and Lutum Technology, LLC. Her work includes a patented sensor design for detecting hydrogen sulfide, a hazardous gas. The available information identifies 1 patent associated with her.

Latest Patents

Shelton’s patent, “Hydrogen Sulfide Sensor and Associated Methods,” describes a sensor built on a substrate with interdigitated electrodes and a homogeneous polyaniline sensing film. The film’s electrical conductivity changes according to the concentration of hydrogen sulfide.

The patent also describes a detection method using multiple sensors with different detection limits across a range. Each sensor generates a signal when exposed to a sample at or above its detection threshold. A fabrication method is also provided: polyaniline polymer and a metal-chloride salt are dissolved in an organic solvent, then spin-coated to create the sensing film on the electrodes.

Career Highlights

Shelton’s listed invention focuses on combining a conductive polymer film with electrode-based sensing to detect hydrogen sulfide. The patent also addresses sensor fabrication and the use of multiple detection thresholds to cover a broader range of gas concentrations. She is associated with Lutum Technology, LLC.
