New Technique Allows Fishing Line and Sewing Thread to be Used to Make Artificial Muscles
”The high cost of powerful, large-stroke, high-stress artificial muscles has combined with performance limitations such as low cycle life, hysteresis, and low efficiency to restrict applications. We demonstrated that inexpensive high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles. Extreme twisting produces coiled muscles that can contract by 49%, lift loads over 100 times heavier than can human muscle of the same length and weight, and generate 5.3 kilowatts of mechanical work per kilogram of muscle weight, similar to that produced by a jet engine.”
Giant Inflatable Balloons Transform Interior Spaces into Otherwordly Environments by Penique Productions | via
Barcelona-based Penique Productions is an artist collective founded in 2007 that creates transformative installations in public spaces. To do this the group utilizes massive plastic balloons that are inflated inside buildings and other interior areas. Coupled with exterior lighting that illuminates the colored plastic, the results can be beautifully dramatic, making the new environment almost unrecognizable from the actual space.
You can see many more views of several installations on their website, and almost all of them are accompanied by videos that document the process. Penrique has upcoming projects next month at both the UB University in Barcelona, and at Galeria N2.
