Chemiresistive hydrogen (H2) gas sensor based on viral-templated Pd nanowires

Moon C.H., Yan Y., Zhang M., Myung N.V., Haberer E.D., University of California Riverside, US

Palladium (Pd) has been widely used for H2 sensing applications because it readily forms a solid solution with hydrogen, modifying electrical resistance. Because the resistance change is diffusion-limited, Pd nanostructured materials with large surface area [...]

A MEMS-type Micro Sensor for Hydrogen Gas Detection

Yoon J-H, Kim B.-J., Kim J-S, Kim B.-J., Kim J-S, University of Seoul, KR

In this study, a highly sensitive hydrogen gas sensor of the multi-layer and micro-heater type was designed and fabricated using a microelectromechanical system (MEMS) process. The dimension of fabricated hydrogen gas sensor was 5 mm×4 [...]
