There are lots of facilities made by steel or plastic in the gym. But what if they are made of paper?
With electricity, liquid and paper, this could work!
Scientists have found out that easily made electro-ribbon actuators could lift weights as human muscles can do. It only takes a piece of flexible material(plastic, paper, etc.) and liquid inside. What’s more, the actuators can shorten by more than 99% of their length. When it comes to product-level use, imagine that the whole gym lifting facilities are made of plastic or paper. Really low cost and definitely environmental-friendly! Fantastic!
