Silent Circle CEO Mike Janke Courtesy of Silent Circle For the past few months, some of the world’s leading cryptographers have been keeping a closely guarded secret about a pioneering new invention. Today, they’ve decided it’s time to tell all. Back in October, the startup tech firm Silent Circle ruffled governments’ feathers with a “surveillance-proof” smartphone app to allow people to make secure phone calls and send texts easily. Now, the company is pushing things even further—with a groundbreaking encrypted data transfer app that will enable people to send files securely from a smartphone or tablet at the touch of a button.
After nanotechnology manages to develop a solution for mobile devices so that they don’t need to be charged every day , I would like if nanotech could lead to a solution for the dropped call. Mobile phones where the batteries run down in a few hours are really annoying but I think dropped calls from bad reception runs a close second in my annoyance scale. I may not have to wait that long if research at the University of Illinois in making a 3D antenna for mobile phones can successfully make it commercially available cell phones. The research, which was initially published in the Wiley journal Advanced Materials , employed an ink jet printing method that used silver nanoparticles and were sprayed on the inside or the ourside of a small hemispherical dome. “To our knowledge, this is the first demonstration of 3D printed antennas on curvilinear surfaces,” Jennifer A.
The US Navy has created a device which turns a jet of sea water into an impromptu liquid antenna, creating a powerful, high frequency broadcast tower for ships, emergency situations and easy transportation.
