Biomimetics is the name of the field which produces technological solutions that mimic those developed by nature itself. Prototypes in organic life are used to imitate these solutions – for example Velcro, which was inspired by the plant kingdom. Biomimetics is also behind a textile solution that can be used to purify
waste water. By mimicking the common eelgrass, an aquatic plant, it is possible to construct a textile structure with a surface of sufficient size to purify water using sunlight and titanium dioxide – a process termed ‘photocatalysis’. Common eelgrass grows in meadows on the seafloor and has long, billowing stalks which absorb sunlight. Using textile imitations, it is possible to create billowing underwater water treatment factories that take care of bacteria and make the water safe for use.
