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.


Why Is My Smart Home So F**king Dumb?

A few weeks ago, a couple friends and I were about to watch a surprisingly bad sci-fi movie in my crowded apartment. One of them asked if we could dim the lights, and started to head to the switch. “No, no, I’ve got it,” I said, reaching into my pocket. “He’s reaching for his phone!” said the friend. This was the moment I’d been waiting for. Time to show off my smart home.


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.


This Cheap Sensor Will Tell Your Phone When Food Goes Bad

Some MIT eggheads invented a very impressive and very inexpensive sensor that stands to protect you against anything from a bomb to a bad pack of beef. And it’s so simple. The new sensor is just a modified near field communication (NFC) chip that can detect the presence of specific gases with the help of carbon nanotubes.


How A Medical Stress Sensor Evolved Into A Beautiful Wearable For All

Seven years ago, an MIT professor named Rosalind Picard developed a wristband called iCalm to help autistic kids manage stress by measuring electrodermal activity on the skin. Today, Picard and her team want to put their device in your hands. What happened in between is a fascinating story about the role of accidental discoveries in science and design.


Smartphone Camera Sensors Are About To Get Even Better

Sony just announced a new sensor for smartphones called the Exmor RS IMX230. This jumbled mess of alphabet soup is a 21-megapixel stacked CMOS imaging sensor that promises higher-quality images to your personal pocket computer. Exactly how will it make your mobile pics more professional? Well, a couple of ways.


Zurich Installed 4500 Street Sensors To Count Every Car In The City

Congestion pricing — the implementation of high tolls to keep cars out of congested downtown areas — is one of the most effective ways to reduce traffic and emissions. Zurich’s plan goes above and beyond that, using a network of sensors to track the number of cars that enter its downtown and prevent more cars from entering until congestion has subsided.
