Telematics Blended wing bodies Surface nanotechnology Optical fibres Bionics Hydrogen fuel cells Match the key terms with the definition

Replaced copper wire. Much faster speeds, with greater bandwidth. Much more information can be transmitted along the same size of cable.

The energy produced is clean, with only heat and water as waste products. Engines that use hydrogen fuel cells are quieter and more simple than petrol or diesel engines.

Different chemicals can be used on materials to give them differing surface properties. One good example is self cleaning windows.

Similar to satellite navigation systems, a telematics system can be used to track locations of vehicles by using GPS references and ICT systems combined.

Different from ‘flying wing’ designs. These aircraft have a distinct wing and body, although much more aerodynamic than existing designs.

Small electronic devices can be used for medical purposes to improve the medical condition of individuals. A pacemaker fitted to regulate a person’s heartbeat is a good example.

New technologies

Optical fibres

Often used in the communications sector, have replaced copper wires.

Hydrogen fuel cells

Chemical energy in hydrogen is converted to electricity. Now an alternative to petrol engines.

Surface nanotechnology

Chemical coatings are applied to the surface of materials to improve their properties.

Telematics

Combines ICT with communications technology to allow vehicles to be tracked.

Blended wing bodies

Advanced aircraft designs consisting of large aerofoil wings joined to an aircraft body.

Bionics

Medical problem solutions using small devices that combine electronics and mechanisms.

New technologies

Optical Fibres

Thin glass wire that we use to send information Computers, communications etc.

New technologies

Hydrogen Fuel Cells

Oxygen in the air + Hydrogen = Energy http://www.bbcamerica.com/top gear/videos/james-tests-honda-clarity/

New technologies

Surface Nanotechnologies

The nanotechnology treatment encourages the water to form droplets on the surface which just run off Useful because it saves us needing to clean tall buildings, improves water resistant clothing https://www.youtube.com/watch?v=XZVH7CASrBk

Surface nanotechnologies:

o Ceramics – produces hygienic surfaces o Metals – resistant to corrosion o Glass – cleaning processes is much less time consuming o Plastics – easier surface cleaning o Textiles – surface becomes water and dirt repellent o Minerals – longer lasting materials

New technologies

Telemetics

Using technology to give us data about products.

Uses: vehicle insurance, road safety, inspecting hard to reach equipment https://www.youtube.com/watch?v=mQ GmEAbNcrg
