It could be that the ZigBee wireless networking spec is just the ticket for those who want to use technology to simplify every aspect of their lives. The 150-plus members of the ZigBee Alliance tout all sorts of applications for IEEE 802.15.4, which was finalized last year. There's been an onslaught of chip unveilings since then. Some predict those chips will see their first usage in industrial applications, while many predict that consumer products from lamps to refrigerators will be the first big market.
Alliance Chairman Bob Heile is in the latter group, feeling that consumer volumes will help give industrial users the assurance that the technology is reliable. Among his many predictions for new products, he thinks the trends toward exotic footwear and health awareness will prompt the creation of ZigBee shoes that send information to an exercise monitor. They will factor in distance and the terrain being traversed to give serious runners instant input on heart rates and calorie counts. ZigBee could even provide an incentive for completing the workout. "The shoe could send a message to the refrigerator when you return home, locking the door if you haven't completed your workout," Heile jokes. www.zigbee.org
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
