A group of engineers from Columbia University has developed synthetic muscles that can lift a load a thousand times heavier than themselves.
Muscles can be printed on a 3D printer, and materials for them are cheap and affordable. New artificial muscles can be used in robots-humanoids and other machines. Muscles consist of silicone rubber, in which microballoons ethanol is located, and a thin wire. When an electric current of 8 V is passed, the muscles are heated up to 80 degrees. As a result, their volume is increased by 900%.
According to experts, using computer control can force muscles to do almost any movement.
