A Georgia Tech inventor has created a system and array of conductometric sensors, devices including conductometric sensors, and methods of making conductometric sensors and gas sensors. This device includes a conductometric gas sensor including a n-type substrate with a porous layer. The plurality of nanostructures are disposed on a portion of the porous layer and provide a fractional coverage on the porous layer. The conductometric gas sensor is used to transduce the presence of a gas into an impedance change, where the impedance change correlates to the gas concentration.
- Functionality — functions across a broad temperature and pressure range
- Durable — works well in elevated temperature environments
- Enhancements — enhanced sensor, micro-reactor, and nanostructure conversion capability
- Development and mediation of MEMS/NEMS sensing/micro-reactor technology
- Hybrid devices with greater sensitivity
- Potential to replace traditional metal oxide sensor system
- Optimal sensor interfaces and arrays and transducing interfaces
Despite significant effort, much of the basic science and technology that can provide a general means to link sensor and micro-reactor design in a framework applicable to detect and transform gas phase analytes and analytes in aqueous solution, has not yet been developed. There is a need for the development of a rational and general approach to generate efficient an interface that can detect, sequester, and destroy harmful analytes.
