Human-Sensing Fan Only Blows Where There Be People

Nothing puts a strain on your local power grid like a hot, humid summer day. In many cities rolling blackouts are needed to cope with the strain, so it makes sense that companies would start developing smarter cooling devices. Quirky's Aros air conditioner is leading the charge, but this smarter oscillating fan is… » 5/16/14 4:20pm 5/16/14 4:20pm

A Graphite Sensor That's Drawn On with a Regular Pencil

Who of us hasn't wished for their own Purple Crayon like Harold's? While this new graphite-based piezoresistive sensor won't make your home come alive with creatures from your imagination, it will provide an inexpensive, easily-applied means of measuring mechanical stresses. You'll just need a pencil and paper. » 2/28/14 6:20pm 2/28/14 6:20pm

These New Sensors Will Turn Passenger Jets Into Flying Weathervanes

Despite our best efforts, accurately predicting the weather remains about as easy as accurately predicting the next winning Powerball numbers. But with the installation of a new type of humidity sensor, the fleets of commercial passenger jets that inhabit our skies could soon provide meteorologists an unprecedented… » 12/16/13 12:20pm 12/16/13 12:20pm

Brave New Interface: A Fleet of Dust-Sized Sensors Embedded In Your…

A few weeks ago, we wrote about a tiny micro-bot designed to be injected into a patient’s eye and controlled via magnet—a speck-sized eye surgeon. This week, a group of Berkeley researchers published a study positing a similar concept, except the ‘bots are inside your brain. And they’re the size of dust particles.… » 7/16/13 3:40pm 7/16/13 3:40pm

Radical New Image Sensor Turns your Entire Display Into a Digital Camera

Researchers at the Johannes Kepler University in Linz, Austria have developed a new kind of image sensor that could one day revolutionize the form factor of digital cameras. Instead of a postage stamp-sized digital eye, the sensor is a flat, flexible, transparent plastic sheet that could be invisibly overlayed on… » 2/22/13 12:40pm 2/22/13 12:40pm

RFID Parcel Sensor Knows If Your Delivery Has Been Dropped

When I was a Christmas postman, many years ago, some of the bored guys in the sorting office's loading bay liked to play a boisterous game of "catch" when parcels marked "video recorder" and "fragile" arrived. How they guffawed when one landed in the bottom of a skip with a sickening crunch, ruining somebody's… » 2/07/13 8:34am 2/07/13 8:34am
