An elastic device uses elasticity—the ability to return to its original shape after being stretched or deformed. This covers various objects from rubber bands to bungee cords. These devices store potential energy when stretched and release it when relaxed. The elasticity allows it to return to the initial shape after the force is removed. It's like a spring but can be more flexible in its application. It's utilized in many applications needing some level of give. Think of it as flexibility built into the design.
