context_page_description: A flexure is a flexible element engineered to be compliant in specific degrees of freedom. Flexures are a design feature utilized by design engineers for providing adjustment or compliance in a design.
context_section_description: Most compound flexure designs are composed of 3 fundamental types of flexure:
  Pin flexure- a thin bar or cylinder of material, constrains 3 degree of freedom when geometry matches a notch cutout.
  Blade flexure- thin sheet of material, constrains 4 degrees of freedom
  Notch flexure- thin cutout on both sides of a thick piece of material, constrains 5 degrees of freedom
  Since single flexure features are limited both in travel capability and degrees of freedom available, compound flexure systems are designed using combinations of these component features.  Using compound flexures, complex motion profiles with specific degrees of freedom and relatively long travel distances are possible.
