Developments in modern materials

Developments in science and engineering lead to changes in materials technology. There are a range of modern materials with impressive properties, as well as traditional ones such as wood or metal.

Input devices allow systems to understand changes in the environment around them. For example, a sensor like a light-dependent resistor (LDR) that senses light levels for street lamps that know when it is dark, or thermistors that detect when it is too hot or cold in a room.
