Tim’s trying out my new electric scooter – and he’s come off and grazed his knee!
Why can’t someone invent super strong skin? That way we wouldn’t get painful grazes like Tim’s!
Despite the fact he’s got a graze, skin’s really amazing stuff. It does a great job at keeping the bits inside our bodies, well, inside.
It also helps keep them at the right temperature.
Of course, there are people who use engineering to help us stay in good health. They’re called biomedical engineers.
Biomedical engineers might be inventing new products such as replacement joints or surgical instruments. Or they might be trialling super tough metals or mega flexible polymers to help keep joints moving for longer.
Other biomedical engineers might be adapting equipment that’s already in use to help people who can’t easily move their bodies to communicate – or even write and paint, by using sensors and computers which translate the movement of their eyes.
It’s not just cool, it can be life-changing stuff.
Now, let’s not forget the really futuristic stuff – you’ve heard of nanotechnology, right?
That’s like the science done on a really tiny scale – building things at the molecular level.
Well there’s plenty of biomedical engineering which gets down to the cellular level – creating treatments and medicines which work within the cells of our bodies, say to deliver drugs to the exact place where they’re needed.
Biomedical engineers might be working with materials like metals and plastics in a workshop, or using IT and computers in an office or coming up with a brand new creation in a laboratory.
