Printed Amperometric Gas Sensors

A new type of amperometric gas sensor, based on screen printing and lamination strategies, has been fabricated and tested. These sensors use thin film electrodes, printed on plastic substrates to form a small, low power (μW) amperometric sensor package, which uses a very small volume of electrolyte....

Summary:A new type of amperometric gas sensor, based on screen printing and lamination strategies, has been fabricated and tested. These sensors use thin film electrodes, printed on plastic substrates to form a small, low power (μW) amperometric sensor package, which uses a very small volume of electrolyte. These sensors have been demonstrated to have improved performance compared to amperometric gas sensors of conventional design, when conventional electrolytes are used. The sensors have also been demonstrated to have promising performance, compared to conventional technology, using room temperature ionic liquid electrolytes (RTILs). The printed sensors have been demonstrated successfully for monitoring of carbon monoxide (CO), ammonia (NH3).
