Fingerprints—those swirling residues left on keyboards and doorknobs—are mostly invisible. They can affirm your onetime presence, but they cannot be used to track your day-to-day activities.

(Phys.org) —A team of researchers at National Taiwan University has developed a sensor for embedding in a single tooth. The sensor as the team explains in their study paper records movement using an accelerometer to identify ...
(Phys.org) —Researchers at Carnegie Mellon University's Biorobotics laboratory have adapted one of their robotic snakes to cause it to automatically wrap itself around an object after being thrown. Upon impact, the snake ...
(Phys.org)—Japanese researchers have taken the science of studying an animal in its natural environment a step further by attaching a camera and accelerometers to Adelie penguins as they forage for food off the waters of ...
(Phys.org)—Researchers at the Berkeley Seismological Laboratory want to table smartphones as pocket-sized seismometers. The phones used as warning systems could make a life or death difference in the seconds one might have ...
In computer science, the buzzword of the day is "big data." The proliferation of cheap, Internet-connected sensors—such as the GPS receivers, accelerometers and cameras in smartphones—has meant an explosion of information ...

(Phys.org)—Intel's new breed of Ultrabooks will be lighter, thinner but loaded with new features and functions that end users will either see as bloat or muscle, and Intel is counting on the latter. The look and functions ...
(Phys.org)—An effort by two engineers and a medical student has resulted in a second glove prototype designed so that doctors can use it as enhanced data. The idea is to enable doctors to quantify touch, said Elishai Ezra, ...
It's a pattern that no doubt repeats itself daily in hundreds of millions of offices around the world: People sit down, turn on their computers, set their mobile phones on their desks and begin to work. What if a hacker could ...

An accelerometer measures the acceleration it experiences relative to freefall. Single- and multi-axis models are available to detect magnitude and direction of the acceleration as a vector quantity, and can be used to sense orientation, vibration and shock. Micromachined accelerometers are increasingly present in portable electronic devices and video game controllers.
