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 H 2 sensors, as shown by W. Lee and co‐workers in their Communication on page 5301 ff.
