MIT researchers developed graphene-coated nylon fibers that bend when heated with laser pulses. In the video, two laser modules are facing each other with the nylon beam coated with thermally conductive paint in the middle. Such nylon filaments are inexpensive to manufacture and could be used to create bending artificial muscle fibers.

Inspired by the comic book character Wolverine’s ability to self-heal, Chao Wang, an adjunct assistant professor of chemistry at the University of California, Riverside, and other researchers have developed a transparent, self-healing, highly stretchable material that can be electrically activated and could be used to improve batteries, electronic devices, and robots.

One Step Closer to Lifelike Robots

A self-contained soft actuator three times stronger than natural muscle, without the need of externals, signals a breakthrough in soft robotics.


The artificial muscle in use as a bicep lifts a skeleton’s arm to a 90 degree position.

Researchers at Columbia Engineering have solved a long-standing issue in the creation of untethered soft robots whose actions and movements can help mimic natural biological systems. Aslan Miriyev and Kenneth Stack, in the Creative Machines lab led by Hod Lipson, professor of mechanical engineering, have developed a 3D-printable synthetic soft muscle, a one-of-a-kind artificial active tissue with intrinsic expansion ability that does not require an external compressor or high voltage equipment as previous muscles required.

Robot brains are getting smarter and smarter, but their bodies are often still clunky and unwieldy. Mechanical engineer Christoph Keplinger is designing a new generation of soft, agile robot inspired by a masterpiece of evolution: biological muscle. See these "artificial muscles" expand and contract like the real thing and reach superhuman speeds -- and learn how they could power prosthetics that are stronger and more efficient than human limbs.
