Learning aim B
Know about developments in
engineering materials and
technologies
Match the key terms with the definition
Telematics
Replaced copper wire. Much faster speeds, with greater
bandwidth. Much more information can be transmitted along
the same size of cable.
Blended wing bodies
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.
Surface nanotechnology
Different chemicals can be used on materials to give them
differing surface properties. One good example is selfcleaning windows.
Optical fibres
Similar to satellite navigation systems, a telematics system
can be used to track locations of vehicles by using GPS
references and ICT systems combined.
Bionics
Different from ‘flying wing’ designs. These aircraft have a
distinct wing and body, although much more aerodynamic
than existing designs.
Hydrogen fuel cells
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.
Bigger picture: Know about new technologies used in engineering (UNIT 1 EXAM in
January 25%)
Learning objectives: o Be able to explain what is meant by the term new technology
o Describe a range of different new technologies used in
engineering
o Explain advantages and disadvantages of a range of new
technologies
Success criteria: o Provide a description of different new technologies and how they
work
o Correctly explain the advantages/disadvantages of a range of new
technology

Optical fibres
Telematics
Often used in the communications
sector, have replaced copper wires.
Combines ICT with
communications technology to
allow vehicles to be tracked.
Hydrogen fuel cells
Blended wing bodies
Chemical energy in hydrogen is
converted to electricity. Now an
alternative to petrol engines.
Advanced aircraft designs
consisting of large aerofoil wings
joined to an aircraft body.
Surface nanotechnology
Bionics
Chemical coatings are applied to
the surface of materials to improve
their properties.
Medical problem solutions using
small devices that combine
electronics and mechanisms.

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

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
