Why A Gecko’s Feet Can Stick To Almost Anything?

In this English through science video, we are going to show you why a gecko’s feet can stick to almost anything.

Thank you, “youtube\Today I Found Out”

The main key of How do gecko’s feet stick to almost anything?

In this English through science section, we are going to explain to you the main key to how do gecko’s feet can stick to almost anything.

Geckos are famous for their ability to scale vertical walls and even hang upside down. As defined by the “Live Science” blog article – Geckos’ Sticky Secret? They Hang by Toe Hairs.

“A gecko by definition is not sticky — he has to do something to make himself sticky,” study lead author Alex Greaney, a professor of engineering at Oregon State University in Corvallis, told Live Science. “It’s this incredible synergy of the flexibility, angle, and extensibility of the hairs that make it possible.”

Why a Geckos Feet Can Stick to Almost Anything?

 

“Geckos can stick to surfaces because their bulbous toes are covered in hundreds of tiny microscopic hairs called setae. Each seta splits off into hundreds of even smaller bristles called spatulae. Scientists already knew that the tufts of tiny hairs get so close to the contours in walls and ceilings that the van der Waals force kicks in. This type of physical bond happens when electrons from the gecko hair molecules and electrons from the wall molecules interact with each other and create an electromagnetic attraction.”

So the main key or secret for Geckos to stick to the walls as explained by the well-known science author Eric Mack on his  interesting  Frobe‘s article about “Gecko’s Sticky Secret: A Lot Of Toe Hair” ” according to researchers at Oregon State University (OSU), is a system of branched hairs on the lizards’ toes and the ability to turn their “stickiness” on or off. The tiny hairs, called “seta” are able to take advantage of what’s called Van der Waals weak atomistic level forces.”

What is Gecko-inspired adhesive?

In this English through science section, we are going to show you the latest invention that scientists mimic from the gecko’s feet can stick to almost anything unique ability.

As a result, as reported by the “Chemistry world“s blog article “Production line for gecko-inspired adhesive“.

Researchers in South Korea have developed a method for continuously producing gecko- foot-inspired adhesive.  By mimicing Gecko’s unique ability to have millions of tiny hairs called setae on their toe pads, which help them cling to surfaces through van der Waals forces.

Since then, many researchers have tried to make synthetic mimics of geckos feet, typically by combining stiff fabrics such as carbon fiber with a soft elastomer rinse like polydimethylsiloxane (PDMS). A mold pattern the mixture into a nanostructure that mimics a geckos foot, which is then cured to maintain its structure.

 

 

From this method they developed the advance Lithography, the lithography is a technique used to draw a pattern on the surface of any substrate in very small scale less than micron or in nano level in electronic materials or devices which are being currently using in market like SIM card, credit card, integrate circuits and many more.

So next time when you see a gecko. please be nice to our little friends because they are amazing.

Also if you want a Gecko pet. I would recommend The leopard gecko. The leopard gecko is probably the most popular pet reptile in captivity today. These small lizards are available in a variety of pleasing colors and patterns. Their care requirements are very simple and they are generally docile and easily tamed.

Thank you for reading my TLearn English through science – Why A Gecko’s Feet Can Stick To Almost Anything article. I hope you found it helpful and useful.
