Are Brainwaves a new type of material ?

Designers played with our minds in 2018, by using electroencephalography (EEG) receptors to read signals from the brain.
Artist Thijs Biersteker and designer David Carson worked together on an installation in the Netherlands that required a pair of visitors to remain calm to keep an imaginary world in order. At London’s Design Museum this summer, the atrium was taken up with a huge air balloon that used visitors’ brainwaves to stay afloat.
