Highly Mobile Palladium Thin Films on an Elastomeric Substrate: Nanogap‐Based Hydrogen Gas Sensors

Abstract

MOTIFE chemical sensors: A novel, low-cost, scalable, and lithography-free but nanogap-based chemical sensing method is presented. This method, termed highly-mobile thin film on elastomer (MOTIFE), utilizes crack formation in a Pd and PdNi thin film generated by stretching the film on an elastomeric substrate to reliably and reproducibly provide highly sensitive H2 sensors.
