Space expert Jeremy Curtis is the United Kingdom’s delegate to the International Space Exploration Coordination Group, which in May 2007 issued a widely cited report calling for global cooperation in manned and unmanned missions to explore the solar system. In addition, he is the coordinator for the UK Space Exploration Working Group and the business development manager for the space science and technology department at Rutherford Appleton Laboratory in Didcot, England. IEEE Spectrum Senior Editor William Sweet interviewed Curtis late last year. Here are excerpts from the interview.

Liquid metal particles sheathed in polymers connect microLEDs to make an ultra-stretchable display.

Korea Advanced Institute of Science and Technology

A team in Korea has used sound waves to connect tiny droplets of liquid metals inside a polymer casing. The novel technique is a way to make tough, highly conductive circuits that can be flexed and stretched to five times their original size.

Making stretchable electronics for skin-based sensors and implantable medical devices requires materials that can conduct electricity like metals but deform like rubber. Conventional metals don’t cut it for this use. To make elastic conductors, researchers have looked at conductive polymers and composites of metals and polymers. But these materials lose their conductivity after being stretched and released a few times.

Modern life now often depends on GPS(short for Global Positioning System), but it can err on the order of meters in cities. Now a new study from a team of Dutch researchers reveals a terrestrial positioning system based on existing telecommunications networks can deliver geolocation info accurate to within 10 centimeters in metropolitan areas.

The scientists detailed their findings 16 November in the journal Nature.
