And also it ends up becoming a very energy intensive process.
So you've made a piezoelectric nylon that only uses a fraction of the energy to make, and you've brought some into the studio with you.
Can I have a look, please?
Yep.
So here you go.
Oh, it's in a little Petri dish.
A little Petri dish.
So these are squares of clear film, each about the size of a fingernail.
It feels not quite as flimsy as a plastic bag that you might get to put your fruit in.
Slightly more rigid, but yeah, that just feels like plastic to me.
Yeah, I mean, when you look at it at the surface, you're like, this is nothing special.
But when you use it in the way that we've shown it to be used, like, for example, running it over with a car, it works.
It produces electricity.
Okay, well, before we get into why you might want to run over it with a car...
You have a new method of making piezoelectric nylon, which involves electrical fields and vibrations.
And together that creates these mini molecular batteries you mentioned before and arranges them stacked neatly so that when you bend it, it can generate electricity.
Yeah.
Okay, so tell me, why have you been driving cars over this nylon material?
There's two ways we can look at using this, and that's either to harvest energy or for sensing.
For example, like embedded in our roads.
