Material that helps you stick to the wall like Spider-Man

Scientists invented a strong adhesive material that can help you stick to the vertical wall, making the fans' dreams come true.

Researchers have created a binder attached to a shoe sole that allows users to walk vertically on the wall, which can be turned on and off with ultraviolet light (or ultraviolet rays).

When illuminated with ultraviolet light, this smart material with a sticky surface will curl.In this way it can lift, transport and drop flat, three-dimensional objects (tall, wide, long).In the picture is a glass globe with a diameter of 1mm.(Photo: Emre Kizilkan).

The German team created a special adhesive sheet inspired by gecko feet. The adhesive is placed on a light-sensitive film containing azobenzene - a molecule that will shrink when exposed to ultraviolet light until completely stopped.

Experts say only a 20-centimeter-wide piece of this material is needed, with an interesting name being light- controlled biologically-controlled transporters with a micro-structure (bioinspired photocontrollable microstructured transport device - BIPMTD) , is enough to lift a grown man, though they have not conducted experiments with humans.

The surface of this material is made of mushroom-shaped molecules that can adhere to any contact surface.

This synthetic material consists of two materials: an adhesive material (green) and an LCE (liquid crystal elastomer) plastic expansion board (yellow).LCE is made from molecular azobenzene capable of bending when illuminated by ultraviolet light.The bending ability makes the adhesive material separate itself from the contact surface with the object.(Photo: Emre Kizilkan / Jan Strüben).

The summary of this study in Science Robotics has written:

"Gecko can crawl on vertical surfaces and below the horizontal surface due to the hierarchical structure below the toe. This structure ensures a strong adhesion, at the same time for rapid separation by jack. like mechanics through foot movement ".

"Inspired by such reactive stimulation systems in nature, we have developed an ultra-compact, artificially controlled, artificial transport device."

Talking to Gizmodo, Emro Kizilkan, team leader from Kiel University's Zoological Institute (Germany) said:

"The overall goal is to create an adhesive material that helps people climb on surfaces."

"However, there are still some concerns about the durability of this material . after many uses."

"When dirty, adhesion may be limited."
