Oxidation

Definition

Oxidation is a chemical reaction that involves the loss of electrons from a substance, which often results in an increase in its oxidation state. This process is essential in various applications, especially in electronics, as it can lead to degradation and failure of materials used in flexible and stretchable circuits. Understanding oxidation helps in addressing reliability issues and developing strategies to mitigate the adverse effects on electronic devices.
