Transient Electronics Dissolve After Use

October 24th, 2012 | by Brita Belli

Most consumer electronic devices—from the iPhone to your laptop—are built on rigid semiconductors that are designed to last (despite your yearly compulsion to upgrade to a new model).

But the emerging field of transient electronics is flipping that notion on its head. Transient electronics, designed to fully disappear after a set amount of time, promise to provide critical health and environmental monitoring and other medical applications without leaving an impact on the body or the natural world.
A team of researchers from Northwestern University, the University of Illinois at Urbana-Champaign and Tufts University came up with the concept.

And it was the concept itself, says Northwestern researcher and engineering professor Yonggang Huang, that was the most challenging part of the process. “We had to study a lot of materials—what’s dissolvable, how to control the dissolution rate,” Huang says. “But the most important is the concept.”
