Plastic material changes the reasoning according to the mechanism of seaweed

A new material inspired by the defense mechanism of sea cucumbers can vary from hard to mild soft, a characteristic that makes it suitable for medical transplants. When wet, this material changes from a hard plastic to a stretchy state like rubber for a few seconds and can return to its original state quickly.

The material simulates a tip of the melon. The invertebrate species can quickly change the hardness of the skin, transforming into an armor when in danger.

According to Chris Weder, Case Western Reserve University researcher, Clevelan, 'We use melon skin as the basis of a new artificial material that can change its mechanical properties when in love. bridge.'
Weder and his colleagues plan to use this material in medicine, such as flexible brain electrodes used to treat Parkinson's disease, stroke or spinal injury.

The material may be in solid form for easier transplantation, then become flexible in fluid-rich brains or in similar tissues . 'If we look at the tissues of the brain, we will see that they are much softer than typical implant electrodes.'

Experimental studies have shown that hard electrodes can reduce the quality of tissue around it after a while. The new material is designed to overcome mechanical inadequacies. It is made of two types of compounds: rubber-like polymer and cellulose fibers to increase rigidity. In the intersection of cellulose fibers, they form hydrogen bonds that give the material stiffness.

'Micro fiber fibers stick together wherever they intersect. If you add water, the water will remove those joints. ' Weder said the water acts as a hydrogen bonding agent.

Weder and his colleagues can stick and remove these fibers in several experiments. Scientists are experimenting on animals to monitor its effects on the brain. Weder said this material has many other applications.'I think there are many applications in the bio-y implant field.'

The same formula can be used to develop variable electrical materials, for example, fish castings or ' smart ' bodies that can be hardened when needed.

And this material can also be used in law enforcement.'Imagine an electrically-modified bulletproof vest that feels comfortable to wear but can switch to bulletproof mode. This has a very important meaning. '
