Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

Small, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.
