Bendability

Definition

Bendability refers to the ability of a material to be flexed or bent without breaking or losing its functional properties. This characteristic is crucial in applications where components need to maintain performance while undergoing repeated bending, such as in flexible printed circuits, which rely on this property for durability and reliability in various electronic devices. A high level of bendability enhances the integration of electronics into dynamic systems, allowing for more versatile designs.
