Micro/nano Gas Sensors for Health, Energy, and Environmental Applications

Gas sensors are important for medical diagnostics, environmental surveillance, industrial safety, agriculture, energy, and homeland security applications. The interest in volatile organic and inorganic compounds analysis has been continuously increasing due to the growing need for safe and heath promoting living and working environments. Rapid gas sensors for operation in complex backgrounds with high accuracy and sensitivity, fast response, and long lifetimes at low cost are demanded for these applications. Recent advances in gas sensors include sensitivity down to a few molecules in clean air or vacuum and sub-second response times, high volume cost-effective manufacturing methods for miniaturization and power reduction. However, as the background complexity increases due to numerous chemicals in the sample, existing gas sensors rapidly lose their validity due to sensor signal drift and sensing materials degradation. This symposium will bring together leading sensor scientists and engineers to share their novel strategies in gas sensor development that emerged from the recent developments in gas sensing technologies such as multi-response gas sensing materials, transducers with multivariable outputs, data algorithms to provide sensor accuracy over expanded periods of time, and packaging concepts that reduce sensor size and power consumption.
