Abstract

In a situation of climatic instability, hydrogen emerges as a promising candidate as an energy vector for storage, distribution, and direct use. Due to its dangerous nature (flammability 4-75%), it must be accurately measured to prevent any potential risks. It is in this context that the CAPTY project aims to develop hydrogen sensors with a low detection threshold (ppm) based on a plasmonic principle called 'plasmon-triggered switch.' The project seeks to address current challenges with a miniature and easy to integrate sensor at low cost, compliant with ATEX standards, with high sensitivity and selectivity for hydrogen.
