Engineers have developed a new sensor using ‘sapphire fibre’

Dot

that is capable of withstanding temperatures over 2,000 degrees celsius

Dot

its high-temperature resistance could mean it could be run through a jet engine

Dot

that could collect necessary data and help us better understand emissions

Dot

it’s capable of withstanding radiation

Dot

This means it can be used in aerospace equipment as well as for fusion energy generation.

Dot

The material is made from industrially-grown sapphire

Dot

When light is sent on one end of it, it reflects it back from a point along it

Dot

Looking at the colour of that light, one can measure the temperature at that particular point
