Graphene-coated nylon as artificial muscle

Published on Nov 23, 2016

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.

Soft materials for soft actuators

Published on Sep 19, 2017

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.

A CHF 12 million donation from the Fondation Werner Siemens will allow EPFL, the Inselspital Bern, and the University Hospital Zurich to develop a Center for artificial muscles.
 

Why scientists are giving robots human muscles

Published on Aug 9, 2018

Human-robot hybrids are advancing quickly, but the applications aren't just for complete synthetic humans. There's a lot we can learn about ourselves in the process.
 

The artificial muscles that will power robots of the future | Christoph Keplinger

Published on May 7, 2019

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.
 

’Artificial muscle’ makes paper doll do sit-ups - Headline Science

Published on Jul 17, 2019

Researchers reporting in ACS Central Science have made a foil “paper doll” sit up using polymer covalent organic frameworks (polyCOFs). ACS Headline Science shows how the team made and tested these potentially useful new materials.
