Covering onion skins with a thin layer of gold makes them stretchy and flexible like muscle fibers, according to the Los Angeles Times and The Independent. Experts explain that the cells under the onion peel are connected in a unique way and remain flexible and soft even when shrinking.
This is extremely difficult to reproduce in existing artificial muscles, say Taiwanese scientists. The specialists actually work at the National University of Taiwan.
They explain that they took a layer of onion cells for the study, then washed them and dried them. Drying is done by freezing so that the water can be removed but the cells remain.
However, this made the layer brittle, so scientists subsequently treated it with a special protein to make it harder. In order to be able to move as a muscle moves, scientists have applied electricity to this layer using special equipment. Previously, experts covered the onion cells with a layer of gold to make them conductive.
When the tension changed, the membrane moved like a real muscle, say Taiwanese experts. Scientists are encouraged that such an invention could prove extremely useful and useful in the development of smart artificial fabrics.
The original goal of Taiwanese specialists was to create an artificial microscopic structure that would increase muscle mobility. They then found that the structure of the onion cells, as well as their size, were very close to what they wanted to do.
At this stage, the only problem is that in order to have movement, the voltage applied must be high. This invention can be helpful to those skilled in the art and to be able to create artificial muscles for robots.
In case the artificial muscles need to be controlled by batteries and a computer chip, the muscles need to work with less energy, the inventors explain.
