Transcript of Woodpecker Helmets
-The study of qualities, traits and processes of nature, understanding how they work and then applying them to man-made designs, structures or systems in order to solve human problems.
-Doesn’t use the actual organisms to solve human issues but instead uses the organisms as blueprints or recipes on how to solve the problems ourselves.
-“How does Nature solve this problem?”
-“Life has created conditions conductive to life” (Janine Renyus on TED: Biomimicry in Action)
-Gathering sustainable innovation inspired by nature.

Concussions in American Football
-Average force of a football tackle is 103 g's ( According to 7thspace.com)
-Humans are often left concussed if they experience 80 to 100g's
-Estimated that high school football players suffered 11.2 concussions for every 10,000 games and practices. Among college players, the rate stood at 6.3. (Estimates are likely conservative because many concussions go unreported and because data on such injuries is limited).
-Many former NFL stars have said they’ve had to battle repercussions in retirement due to concussions sustained when they played football, including depression, suicidal impulses, Alzheimer’s disease or the neurodegenerative condition chronic traumatic encephalopathy (CTE).
-FRONTLINE reported in 2000 that the NFL’s official helmet provider, Riddell, was warned that even a helmet that passed industry safety standards for protection against skull fractures and other severe head injuries could still leave a player with a 95 percent likelihood of receiving a concussion.
-21 species in North America and occupy every state.
-Size: 3-21 inches in length.
-Are diurnal omnivores/ opportunists, eating mainly grubs and insects.
-Drill holes and excavate nest in trees by rapidly pecking at the wood with their beaks. Drum on trees at up to 22 times per second, experiencing deceleration of 1200g’s.
- Have specialized beaks and brain compartments designed to allow for their vigorous pecking. Brains are suspended in their skull by shock cords and extensive muscle mass, beaks are extremely strong, tongues rap around the skull,

-Sang-Hee Yoon and Sungmin Park of the University of California, Berkeley have already studied and applied the abilities of the woodpecker to resist large amounts of force, creating a shock absorber system to protect electronics in planes in chase of a plane crash.
-Yoon and Parker break the woodpecker’s anatomy into 4 parts: 1)hard-yet-elastic beak; 2) the hyoid, a sinewy, springy tongue-supporting structure that extends behind the skull; 3)an area of spongy bone in the skull; 4) the interaction between the skull and cerebrospinal fluid which suppress vibration.
-In a test run, the system protected against 60,000g’s of force.
-Sturdy/unbreakable outer shell that can shift around the inner layers; bouncy, shock absorbent mid-layer; Unyielding final layer; tight fitting foam layer cushions the head
-Applying this system to helmets could reduce head injuries tremendously and save the game of football from “the nut job football rules reactionaries of 2013 who’ll de-evolve it into touch in 20 years.”
