Origami inspires super strong artificial muscle

Developed by engineers from Bristol Robotics Laboratory and Engineering Mathematics, the device is said to be as thin as paper but capable of lifting 1,000 times its own weight. Furthermore, the structures can be made from any combination of insulating and conducting materials.

“With electro-origami, we can replace electromagnetic motors with light, scalable, silent alternatives,” said Dr Majid Taghavi, one of the inventors of the technology. “Because electrostatic devices do not require high currents, they produce much less heat and can be much more efficient than electric motors.”

The research, published in Science Robotics, comes from the same team that previously developed smart robotic trousers to improve the mobility of older adults and people with disabilities.

“We first discovered the electro-origami concept more than two years ago, whilst developing artificial muscles for assistive robotic clothing, however it has wide applications across engineering and robotics,” said, Dr Tim Helps, who co-authored the study alongside Dr Taghavi and Prof Jonathan Rossiter at the University’s SoftLab.
