The Best Way To Map Radiation? Bento Boxes Stuffed With Geiger Counters

Back in 2011, a team of volunteers crammed Geiger counters into bento-shaped boxes to map the radiation following the Fukushima meltdown. It turned into the biggest collection of radiation data in history. Next up: tackling air pollution.


This Seal Has A Sensor On Its Head For Gathering Data About Antarctica

It is not easy for a human to traverse the deep, cold waters of Antarctica. It is easy, however, for seals to swim through them. For the past decade, scientists have been turning elephant seals into live, swimming sensors to monitor those waters. Now, the data’s going public.


Project Jacquard Hands-On: Google Is Putting Sensors In Fabric

Roaming around the floor of Google I/O we got our hands on one of the prototypes from ATAP, Google’s DARPA-like experimental lab. It’s called Project Jacquard, and it’s nice n’ soft. It’s a fabric that can control your phone.


The World's First Self-Powered Video Camera Can Record Forever

It makes perfect sense. The sensors that capture images for a digital camera and the sensors that convert light into electricity for a solar cell rely on the same technology. So why not build a device with a sensor that does both, and create a self-powered video camera? Some Columbia University researchers did just that.


The Guerrilla Movement To Deploy Sensors All Over Your City

“You want to see our sensor?” Pierre Forcioli-Conti gestures at a high window that leads to the roof. “You’ll have to climb over Matt’s desk and go out the window.” No problem. I wriggle through the window and climb out on top of the the refurbished 1940s movie theatre on Mission Street in San Francisco. It doubles as his office.


Pencil Lines Can Turn A Piece Of Paper Into A Simple Sensor

The graphite that slips from the point of your pencil onto a page may be of more use than simply writing and drawing. A team of researchers has shown that simple pencil lines can be used as an accurate sensor to measure the deformation of objects.


This Stamp-Sized Sensor Can Sniff Out Explosives Using RFID Tags

Detecting explosives is, obviously, an important task — but many of the sensors are large and require manual operation. So GE’s tiny and affordable new RFID sensor could help automate the process, to help keep us safe without much in the way of man power.


Turn Your Valuables Into A Mesh Network So You Never Lose Them

Losing things is a pain, partly because you spend so much time looking for them. A new technology called Pixie is trying to solve that problem, and even make tracking down your misplaced valuables kinda fun, by turning them into a connected network you can search with an augmented reality interface.


The Long Tentacle On This Wireless Sensor Alerts You To Water Leaks

Nothing can ruin a holiday faster than worrying about what might be happening in your home while you’re away, and security cameras and motion sensors don’t always spot every problem. For a little more peace of mind, D-Link’s new Wi-Fi Water Sensor features a long flexible cable that can detect and immediately alert you about the smallest of water leaks before they turn into major disasters.


WeMo Beefs Up Smart Home Lineup With Four New Sensors

Right now, piecing together a smart home, your very own domicile outfitted to perfectly fit your life, is a confusing cobweb of wireless standards, compatibility, and brands — lots and lots of brands. But the first step into this brave new connected world is just giving your home awareness, and that’s what Belkin WeMo’s new sensors, just announced at CES, are all about.
