Beside eco-friendly materials, 3D printing and wearable technologies can receive the wider application by 2020. Big sports brands, such as Nike, Puma, and Adidas, have been working with 3D printing for about five years; designer Iris van Herpen create sophisticated fashion items on 3D printers; technological brands, like Google and Apple, actively promote wearable technology. Altogether, technological clothes are not so widely spread as one would expect. Among recent commercially successful projects, one can recall a smart jacket with conductive threads inside of it to conduct electricity by Levi's and Google. Among other things, wearable technology can be used to charge gadgets or change the form of clothes on the go. Such garments have not yet received a widespread use. Experts say that this is a matter of time. For example, Snezhana Paderina, designer and ambassador of 3D printing and wearable technologies in Russia, says that the biggest problem of wearable technologies is a battery that still has to be rather large. However, more flexible and flat batteries are being developed. When the production of such batteries will be accomplished, it can result in a new technical revolution. Taking into account that today new technologies reach people very quickly, it is likely that we will perceive "smart" clothes as something more familiar in 2020.
