A lithography-free but nanogap-based chemical sensing method utilizes crack formation in a Pd or PdNi thin film generated by stretching the thin film on an elastomeric substrate. This low-cost, scalable method that uses a highly mobile thin film on an elastomer (MOTIFE) provides reliable, repeatable, and highly sensitive H2 sensors, as shown by W. Lee and co-workers in their Communication on page 5301 ff.
