Comments Off on Make calls with light or radio signals thanks to first battery-free cellphone

Imagine never having to charge your smartphone ever again. We may be one step closer to that battery-free future with new research from University of Washington engineers. They made a phone capable of calling people drawing on light or ambient radio signals. Associate professor Shyam Gollakota said they think it could be the “first functioning cellphone that consumes almost zero power .” No, it’s not magic – the University of Washington’s battery-free cellphone can function on just a few microwatts of power it harvests from RF signals coming from a base station around 31 feet away, or from light via a minute solar cell that’s about the size of a grain of rice. The team constructed their prototype from off-the-shelf components and have already used it to make Skype calls. Related: MIT’s New Battery-Free Chip Captures Energy From Light, Heat, And Vibrations at the Same Time The cellphone prototype is able to run on such low power in part because the team got rid of the step to convert analog signals into digital data – a process that sucks up a lot of power in modern cellphones. Their battery-free phone can make use of small vibrations from the speaker or microphone that come when a person is talking or listening while making a call. According to a university press release, “An antenna connected to those components converts that motion into changes in standard analog radio signal emitted by a cellular base station. This process essentially encodes speech patterns in reflected radio signals in a way that uses almost no power.” The team designed their own base station to receive and transmit radio signals. But that technology could be embedded in cell towers or even Wi-Fi routers in the future. Research associate Vamsi Talla said if every home has a Wi-Fi router – as many already do – “you could get battery-free cellphone coverage everywhere.” The research was recently published in the Proceedings of the Association for Computing Machinery on Interactive, Mobile, Wearable, and Ubiquitous Technologies . The team plans to keep working on the technology to increase the operating range and encrypt conversations. They also aim to stream video on battery-free cellphones. + Battery Free Phone Via the University of Washington Images via Mark Stone/University of Washington

Apple’s water-resistant iPhone 7 will fight e-waste due to drowned gadgets

Comments Off on Apple’s water-resistant iPhone 7 will fight e-waste due to drowned gadgets

E-waste is a pressing modern issue: according to the EPA, over 60 million metric tons of e-waste , or electronic waste, enters landfills every single year. iPhones and Apple Watches are among the offending devices casually tossed out each year – the company has sold over a billion of the phones but few are recycled properly. Today at their event in San Francisco, Apple their new iPhone 7 and Apple Watch Series 2. Both are water resistant. Related: Apple just unveiled a blazing fast iPhone recycling robot Apple’s Twitter account actually leaked the detail that the iPhone 7 is water resistant. According to Apple Senior Vice President of Worldwide Marketing Phil Schiller, the new enclosure on the iPhone 7 means it is water and dust resistant. Apple COO Jeff Williams spoke about the Apple Watch Series 2: a “completely re-engineered” watch. According to Williams, while the first Apple Watch was splash-proof, the Apple Watch Series 2 is actually “swim-proof.” He said users can wear it while swimming , surfing, or even during the “occasional cannonball.” Apple created new seals and adhesives to close entry points where water could leak into the device, but one area that was hard to seal was the speaker. According to Williams, they redesigned the speaker system so they can actually “use the speaker itself” to “eject water.” The watch won’t just be swim-proof for a lap every once and a while, but for those who swim daily. Apple tested the Watch in a simulator to see that it would last for those who swim over the course of several years, for “hundreds of thousands of strokes.” + Apple
