What if devices could pull enough power wirelessly from the air to run themselves and send signals?
Mobile devices have become radically smaller and more powerful in the past 10 year. The list of tech-related tasks that the mobile devices we all carry around has grown longer by the year. The next step in technology’s great disappearing act? Absorption into our clothes, body, and environment.

Will high-speed car chases become a thing of the past? A company in the U.K. has developed a prototype that could stop cars in their tracks by blasting electromagnetic waves.

Engineers have developed a wireless network of radio transmitters that can track people moving behind solid walls. The system could help police, firefighters and others nab intruders, and rescue hostages, fire victims and elderly people. It also might help retail marketing and border control.

Electronics such as phones and laptops may start shedding their power cords within a year.
That’s the prediction of Eric Giler, CEO of WiTricity, a company that’s able to power light bulbs using wireless electricity that travels several feet from a power socket.
A cell phone that never needs recharging might sound too good to be true, but Nokia says it’s developing technology that could draw enough power from ambient radio waves to keep a cell-phone handset topped up.

A tiny injectable implant, smaller than a grain of rice, might one day take the place of large neural stimulators used to treat chronic pain and other neurological disorders. The novel device, under development by MicroTransponder, a Dallas-based startup, owes its small size to the use of RFID (radio-frequency identification) technology like that used to tag clothes to prevent shoplifting.

From mundane traffic overpasses to marvelous feats of soaring engineering, bridges are something we tend to take for granted – until something goes wrong that is. A team from the University of Michigan is leading a five-year, $19 million project to engineer an intelligent infrastructure monitoring system designed to prevent tragedies like the collapse of the Interstate 35 West bridge over the Mississippi river in 2007 in which 13 people were killed and 145 were injured.
