A woodpecker is known to drum the hard woody surface of a tree at a rate of 18 to 22 times per second with a deceleration of 1200 g, yet with no sign of blackout or brain damage. As a model in nature, a woodpecker is studied to find clues to develop a shock-absorbing system for micromachined devices. Its advanced shock-absorbing mechanism, which cannot be explained merely by allometric scaling, is analyzed in terms of endoskeletal structures. In this analysis, the head structures (beak, hyoid…

TLDR
Analytical results shows that these bio-inspired mechanical systems can effectively absorb the strong shock or reduce the amplitude of the vibration from the outside and protect the inside devices without damage.

Numerical study of the impact response of woodpecker's head
Woodpecker can beat trees 20-25 times per second and lasts for several seconds, with a 1200 g deceleration, but it appears that they never get brain concussion. How does the stress wave propagate
Response of Woodpecker's Head during Pecking Process Simulated by Material Point Method
TLDR
This study found that the existence of the hyoid bone reduces the SSS level, enhances the rigidity of the head, and suppresses the oscillation of the endoskeleton after impact.
How woodpecker avoids brain injury?
It has long been recognized that woodpecker is an excellent anti-shock organism, as its head and brain can bear high deceleration up to 1500 g under fast pecking. To investigate the mechanism of
Energy conversion in woodpecker on successive peckings and its role on anti-shock protection of brain
To investigate the mechanism of brain protection of woodpecker, we built a finite element model of a whole woodpecker using computed topography scanning technique and geometry modeling. Dynamic

Mechanical Evaluation of the Skeletal Structure and Tissue of the Woodpecker and Its Shock Absorbing System
TLDR
It is considered that woodpecker has the advanced impact-proof system relating with not only the head part but also with the whole body, as the unique states of hyoid bone, skull, tissue and brain.

Woodpecker pecking: how woodpeckers avoid brain injury
TLDR
There are three keys to woodpeckers' ability to withstand high decelerations: their small size, which reduces the stress on the brain for a given acceleration; the short duration of the impact, which increases the tolerable acceleration; and the orientation of the brain within the skull,Which increases the area of contact between the brain and the skull.
A Quantitative Analysis of Woodpecker Drumming
TLDR
Modulation of the drum in sapsucker species could minimize signal equivocation between syntopic woodpecker species with a matching introductory cadence, postulated as a possible selective pressure favoring the diagnostic long call prevalent in the species, rather than drumming.
