Abstract
A hydrogen sensor and/or switch fabricated from an array of nanowires or a nanoparticle thick film composed of metal or metal alloys. The sensor and/or switch demonstrates a wide operating temperature range and shortened response time due to fabrication materials and methods. The nanowires or nanoparticle thick films demonstrate an increase in conductivity in the presence of hydrogen.
