Conventional cotton and synthetics can be turned into a rechargeable batteries, and material properties are kept intact. Technology is a further development of the concept of “worn electronics”, where the device is integrated directly into clothing and textiles. Copyright of the design belongs to associate Professor of materials science and engineering at Stanford University (Stanford University) Yui Kyu (Yi Cui), which we mentioned earlier in connection with the supercapacitors based on paper and “ink” made of nanotubes with a single wall. As in the case of capacitors, the fabric is impregnated with “ink”. Recent studies show that allocation (in particular print) electronics on non-traditional surfaces of circuit boards, including flexible and transparent, is not fiction. But integrating it into the fabric is a bit different task.

Kyu with his team demonstrated that the twisted fibers, like paper, can absorb ink and thanks nanotubes to maintain electrical conductivity throughout the material and, respectively, of the garment. Thing is immersed in “dye” and then dried, as is done in the production of colored fabrics. It is argued that even rinsing in water does not change the acquired properties, and the number of charge cycles created from the fabric of the supercapacitor can reach a million. Next target are the materials that store more energy, and replacement of nanotubes are potentially cheaper graphene. Possibly by combining nanotubes and other materials scientists ever present worn solar cells.
