Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com.

I'm Cody Gough. And I'm Ashley Hamer.

Today you learn about why engineers tested a temporary smart tattoo that emits light, a female vampire bat that adopted her

best friend's baby, and how you can sharpen your mind with device-free

quiet time. Let's satisfy some curiosity.

Scientists at University time. Let's satisfy some curiosity.

Scientists at University College, London and the Italian Institute of Technology

have taken wearable tech to a whole new level.

They've created a temporary tattoo that glows and it's good for more than your

next rave. This techie tattoo relies on the same components that create the display on your TV, or smartphone.

They're called organic light-emitting diodes or oleads.

The temporary tattoo sandwiches the oleed between two insulating layers that have electrodes inside.

The electrodes create the circuit that makes the oleed light up.

Those three layers are stuck to the same kind of adhesive paper that you would use with a regular temporary tattoo, like you would pass out at a kid's birthday party.

You stick it on the same way with water and a little bit of pressure and the whole thing is incredibly

thin thinner than a red blood cell but this tattoo isn't just a fashion

statement the team was able to stick the device on paper, plastic, glass, and even

an orange. Their hope is that electric tattoos could help keep your fridge fresh by lighting up when say your milk or bananas are

about to expire. They can also help keep athletes safe by hooking up to sweat sensors

and illuminating when an individual is dehydrated.

Imagine that, glow in the dark Ashley at the end of a marathon.

I'd wear it.
