Highly ordered palladium nanodot patterns for full concentration range hydrogen sensing

Abstract

A hydrogen sensor based on a novel fabrication process that combines the precision of advanced nano-fabrication techniques with a bottom-up process based on electrochemistry is presented. The sensor allows for reliable detection between 0.1% and 100% of H₂ in air. This fabrication is very versatile, highly reliable, and fully scalable for mass production, representing a very promising option for the fabrication of the next generation hydrogen sensors.
