NOVA : What can nature teach us in building smarter materials? Can we create materials that sense and respond? “When describing ‘smart materials,’ one analogy scientists give is the evolution from the first Terminator robot, a machine made of metal and circuitry, to the shape-shifting ‘liquid guy’ in Terminator 2,” said Making Stuff producer Chris Schmidt. Smarter looks into the growing number of materials that can shape themselves–reacting, changing, and even learning. An Army tanker trunk that heals its own bullet wounds. An airplane wing that changes shape as it flies. Clothing that can monitor its wearer’s heart rate, health, and mood. For inspirations and ideas, scientists are turning to nature and biology and producing some innovative new developments in materials science. The sticky feet of geckos have yielded an adhesive-less tape. Studying the properties of skin has led to the development of self-healing protective foam. And Pogue literally goes swimming with sharks to understand a different kind of skin that is intriguing scientists. Scientists are modeling a material after sharkskin to develop an antibacterial film that, when sprayed in hospitals, could eliminate MRSA and other anti-biotic resistant bacteria from clinging to surfaces. Pogue also visits a scientist who has created a material that can render objects invisible. “Smarter” concludes with a vision of the future, the ultimate in “life-like” stuff: programmable matter that could create a duplicate of a human being.
