OPTICAL FIBRES

Optical fibres started to replace some uses of copper cables in the 1970s. They are made from glass and are usually about 120 micrometres in diameter. Some of the most common everyday uses are in telecommunications, close-circuit television (CCTV) and cable television.

Optical fibres carry signals more efficiently than copper cable and with a much higher bandwidth. This means that fibres can carry more channels of information over longer distances. Optical fibres cables are much lighter and thinner than copper cables with the same bandwidth. This means less space is needed in underground cabling ducts.

Optical fibres are more expensive per metre than copper. However, one optical fibre can carry more signals than a single copper cable and the longer transmission distances mean that fewer expensive repeaters are required. Also copper cable uses more electrical power to deliver the signals.

Optical fibres can’t be sliced as easily as copper cable. Employees need special training to handle the expensive splicing and measurement equipment.

SMART MATERIALS

Smart or shape memory materials are an invention that has changed the world of engineering. There are two types: metal alloys and plastic polymers. The metal alloys were made first and they are usually an expensive mixture of titanium and nickel.

Shape memory materials are called “smart” because they react to changes in their environment. For example, plastics that return to their original shape when the temperature changes. One use is in surgery where plastic threads “remember” the shape of a knot, react to the patient’s body temperature and make themselves into stitches.

Metal alloys that have a “memory” and can return to their original shape. They are used in medical implants that are compressed so they can be put inside the patient’s body through a small cut. The implant then expands back to its original shape. More everyday uses are for flexible spectacle frames and teeth braces. Liquid crystals that change shape and colour are used in climbing ropes.

The future of smart materials and their possible uses is limited only by human imagination.
