Scientists made cutting edge ‘smart skin’ with Post-its, foil and tape
The Washington Post

Human skin may be the ultimate multitasker: It can sense pressure, feel temperature and detect humidity and motion – all at the same time. It’s no wonder, then, that it’s been tricky and expensive for scientists to create a direct analog for the stuff.

But those scientists weren’t Muhammad Mustafa Hussain — and apparently they weren’t using the right office supplies. Hussain and his team just developed a dirt-cheap “smart skin” that can multitask like the real thing, and they did it with household goods, such as Post-It notes, aluminum foil and tape.

Hussain, who just published the results in the inaugural edition of the journal Advanced Materials Technologies, is an associate professor of electrical engineering at the King Abdullah University of Science and Technology in Thuwal, Saudi Arabia. He heads the university’s Integrated Nanotechnology Laboratory, a place where engineers use everything from Lego to saliva to stickers to solve the world’s problems.
