Engineers at BAE Systems’ Advanced Technology Centre are working on a concept to give aircraft human-like ‘skin’, which is claimed to detect wind speed, temperature, physical strain and movement more accurately than existing technology.
Embedding tens of thousands of micro-sensors into the aircraft body, the ‘smart skin’ concept is said to enable an aircraft to monitor its health and report potential problems, thereby reducing the need for regular check-ups on the ground.

BAE Systems said that the sensors are as small as dust particles and have their own power source.
On connecting with the appropriate software, the sensors will be able to communicate in a similar way as the human skin.
BAE Systems said: "The sensors are so small that we are exploring the possibility of retrofitting them to existing aircraft and even spraying them on like paint."

By GlobalDataLed by senior research scientist Lydia Hyde, the R&D is part of a range of next-generation technologies being explored by BAE for air platforms.
Hyde said that the idea for the concept came while using a tumble dryer, which uses a sensor to prevent it from overheating.
"Observing how a simple sensor can be used to stop a domestic appliance overheating, got me thinking about how this could be applied to my work and how we could replace bulky, expensive sensors with cheap, miniature, multi-functional ones," Hyde said.
"This in turn led to the idea that aircraft, or indeed cars and ships, could be covered by thousands of these sensors creating a ‘smart skin’ that can sense the world around them and monitor their condition by detecting stress, heat or damage.
"The idea is to make platforms ‘feel’ using a skin of sensors in the same way humans or animals do."
