Do you know what the lightest material on the Earth is? Well, don’t be shamed, if you cannot answer the question! Let’s reveal the answer here: Aerogel!
For your information, aerogel is a solid-state material with the lowest density of all material forms. Normally, it is derived from gel in which the liquid component of the gel has been replaced with gas. Samuel Stephens Kistler is the person who invented aerogel in 1931.
Recently, a group of scientists from Texas has created the super lighted artificial muscles that based on aerogel and can do many wonderful things. Beside that, the material scientists have created a variety of different artificial muscles, which can expand and contract when an electrical charge is applied.
The remarkable thing about this artificial muscle is even at very high voltages; the muscle can still expand and contract with no fatigue at all.
This artificial muscle claims 30 times stronger than human muscle. An electrical charge of less than a volt can cause the artificial muscle to expand 220 percent in milliseconds, which is many times faster than normal human muscle can move!
“It’s definitely a new breakthrough for the aerogel, and we can expect many incredible things to come in the future!” said Ray Baughman, the study author from the University of Texas at Dallas.
