  "abstract": "A method of forming an adhesive force includes removing a seta from a living specimen, attaching the seta to a substrate, and applying the seta to a surface so as to establish an adhesive force between the substrate and the surface. The seta is applied to the surface with a force perpendicular to the surface. The seta is then pulled with a force parallel to the surface so as to preload the adhesive force of the seta.",
  "claims": [
    "1. A method of establishing an adhesive microstructure, said method comprising the steps of applying a fabricated artificial seta to a surface with a force perpendicular to said surface; pulling said seta with a force parallel to said surface so as to preload an adhesive force of said seta.",
    "2. The method of claim 1 wherein said adhesive force is greater than the cumulative force of said applying and pulling steps.",
    "3. The method of claim 1 further comprising the step of eliminating said adhesive force by creating a force to produce a detachment angle between said seta and said surface.",
    "4. The method of claim 3 wherein said eliminating step includes the step of creating a force to produce a detachment angle of between 25° and 35° between said seta and said surface.",
    "5. The method of claim 3 wherein said eliminating step includes the step of creating a force to produce a detachment angle of approximately 30° between said seta and said surface."
