(Picture 1) Kimmo Huosionmaa Making artificial muscles helps to make nano drones and another kind of things, what needs extreme flexible material. The first one is the biotechnical method, where the normal muscle cells would be grown on the nutrient base. After the necessary number of cells have been grown, and then their nucleus and other things, what is inside those cells can be filled with silicon other other inorganic material, and then both sides of the muscle cells would be connected the electric wire. After this those cells would be covered by the plastic layer, that is emptied of air. The thing what makes the muscle cell to pull and push are the myofibrils, what are in the outer layer of the cell. This technology is based on the same experiment, what is made by Galvani in 18th. century. He connected one of his batteries to the cut frog feet, and he noticed, that the electricity makes those feet to move. Also, neurons could be pulled empty, and then fill them with in...
