Anisotropic properties

Definition

Anisotropic properties refer to the directional dependence of a material's physical characteristics, meaning that the material exhibits different behaviors when measured along different axes. This is particularly relevant in flexible and stretchable electronics, where the performance of materials can vary significantly depending on their orientation and the specific conditions they are subjected to, impacting their functionality in devices like antennas.
