Extending these advantages to chemical sensing is challenging because electrochemical readouts depend on coupled electrical transport and interfacial reactions, both of which are readily compromised by mechanical deformation. In practice, stretching alters resistance of the electrical circuit, changes the electrochemically active surface area, and modulates interfacial kinetics and mass transport, which together distort voltammetric and amperometric signatures and introduce baseline drift. …
