Electronic skin tattoo has medical, gaming, spy uses

A hair-thin electronic patch that adheres to the skin like a temporary tattoo could transform medical sensing, computer gaming and even spy operations, according to a US study published Thursday.

The micro-electronics technology, called an epidermal electronic system (EES), was developed by an international team of researchers from the United States, China and Singapore, and is described in the journal Science.

"It's a technology that blurs the distinction between electronics and biology," said co-author John Rogers, a professor in materials science and engineering at the University of Illinois at Urbana-Champaign.

"Our goal was to develop an electronic technology that could integrate with the skin in a way that is mechanically and physiologically invisible to the user."

The patch could be used instead of bulky electrodes to monitor brain, heart and muscle tissue activity and when placed on the throat it allowed users to operate a voice-activated video game with better than 90 percent accuracy.

"This type of device might provide utility for those who suffer from certain diseases of the larynx," said Rogers. "It could also form the basis of a sub-vocal communication capability, suitable for covert or other uses."

The wireless device is nearly weightless and requires so little power it can fuel itself with miniature solar collectors or by picking up stray or transmitted electromagnetic radiation, the study said.

Less than 50-microns thick -- slightly thinner than a human hair -- the devices are able to adhere to the skin without glue or sticky material.

Confessed Spy Convicted of Exporting U.S. Crypto Gear to China

wired.com

A Chinese national was convicted this week of smuggling and other charges over his efforts to acquire sensitive military and NSA-encryption gear from eBay and other internet sources.

Chi Tong Kuok, of Macau, told Defense Department and Customs investigators that he had been “acting at the direction of officials for the People’s Republic of China,” according to a government affidavit in the case. “Kuok indicated he and PRC officials sought the items to figure out ways to listen to or monitor U.S. government and military communications.”

Kuok was arrested at the Atlanta International Airport last year en route from Paris to Panama, where he planned to meet an undercover federal agent he believed was going to provide him with military radios. He was transferred to California and indicted (.pdf) for money laundering, conspiracy, smuggling and one count of attempting to export a defense article without a license. On Tuesday, a jury convicted him on all counts.

The world's top producers of computer memory chips are embroiled in an apparent case of industrial espionage after South Korean prosecutors indicted 18 people over alleged technology theft.

Prosecutors said Thursday those involved — including employees of U.S. company Allied Materials and its South Korean unit — are suspected of leaking semiconductor technology belonging to South Korea's Samsung Electronics Co. to its domestic rival Hynix Semiconductor Inc.

The case highlights the intense competition among chipmakers and other sellers of high tech products, who frequently sue each other over alleged patent infringements.
