239th ECS Meeting with IMCS Topic Close-up: Electrochemical and Metal Oxide Sensors

Symposium focus: The development of electrochemical (based on ionic conduction—potentiometric, amperometric, and mixed potential) and metal oxide (based on electronic conduction—conductometric) gas sensors has a long history, and their optimization and miniaturization is a source of continued research. The major focus is to improve selectivity, stability, and reproducibility of the sensor response, in addition to novel methods for synthesis of metal oxide nano-hetero-structures with unique properties and novel sensing mechanisms, and the characterization of the arrays of metal oxide sensors. All relevant topics on gas sensors and biosensors based on electrochemical principles including amperometric, potentiometric, mixed potential, and conductometric devices for both room temperature and high temperature gas sensing are welcome. Please check out the call for papers for more details.
