Korean Researchers Announce High-Speed, Low-Power RF Chip

Korea Advanced Institute of Science and Technology researchers have developed a low-power, 60-GHz RF chip that wirelessly transmits large amounts of data between devices. The integrated circuit reportedly can send data up to 10.7 Gbits per second. Bluetooth high speed technology, for comparison, has an average data transfer rate of 24 Mbps. Existing high-speed wireless chips require significant amounts of energy, which has delayed their development. The new chip uses as little as 67 mW of power: 31mW to send and 36mW to receive data. The compact device also has a single antenna and an integrated switch. The researchers say the chip can be installed on mobile devices or cameras.(EurekAlert)(Korea Advanced Institute of Science and Technology @ EurekAlert)(Korea Advanced Institute of Science and Technology @ YouTube)

Researchers Develop Stretchy Electronic Material

An international research team has developed a material that can be used to create electronics capable of stretching to more than double their original size. Scientists from Northwestern University’s McCormick School of Engineering, the Korea Advanced Institute of Science and Technology, Dalian University of Technology in China, and the University of Illinois at Urbana-Champaign created the new material by combining a porous polymer (porous polydimethylsiloxane) and a liquid metal (eutectic gallium-indium). This combination lets electricity flow consistently through the device, even when it is being stretched. Loss of conductivity is a common problem with existing stretchable electronics. The researchers said the new material is four times stretchier than conventional elastic electronics materials. They noted that healthcare and other applications could use stretchy devices. They published their research in Nature Communications. (EurekAlert)(Northwestern University)(Nature Communications)
