High Temperature Sensor Selective for Propane and Other Reducing Gases

摘要

Exemplary embodiments of the present disclosure relate to sensor technology for gases, and more specifically, to nanofiber based gas sensors capable of operating at high temperatures (e.g., hundreds, thousands of degrees Celsius). In exemplary embodiments, a combination of p-type and n-type nanofiber materials can be combined to create gas sensors that can be used to detect reducing gases with enhanced selectivity/sensitivity.

主权项

1. A sensor comprising:
a substrate; one or more electrodes disposed on the substrate; and an electrospun nanofiber composite formed of a p-type nanofiber material and an n-type nanofiber material, wherein the nanofiber composite formed by the p-type nanofiber material and the n-type nanofiber material have selectivity towards detecting a specified type of gas.
