Velcro

Definition

Velcro is a brand name for a type of fastener made up of two components: one side covered in tiny hooks and the other side made of loops. This innovative design mimics the natural mechanism found in burdock burrs, which attach to animal fur or clothing, showcasing the principles of biomimicry where human designs are inspired by nature. Velcro has become a staple in various industries due to its unique ability to create a strong yet easily releasable bond, highlighting its practical application in modern innovations.
