Building a wireless micromachine

All around us, hiding just outside our range of vision, are miniscule machines. Tiny accelerometers in our cars sense a collision and tell the airbags to inflate. A Nintendo Wii controller's tiny gyroscopes translate your ...

Detecting disease in beef cattle using ear tag units

A smartphone switches its orientation from portrait to landscape depending on how it's tilted. A car's airbags inflate when it senses collision forces. By detecting earth's vibrations, a computer can measure the magnitude ...

Smart phones spot tired drivers

An electronic accelerometer of the kind found in most smart phones that let the device determine its orientation and respond to movement, could also be used to save lives on our roads, according to research to be published ...

Bio-inspired eye stabilizes robot's flight

Biorobotics researchers at the Institut des Sciences du Mouvement - Etienne-Jules Marey (CNRS/Aix-Marseille Université) have developed the first aerial robot able to fly over uneven terrain that is stabilized visually without ...

Measuring earthquake shaking with the Community Seismic Network

In 2011, the Community Seismic Network (CSN) began taking data from small, inexpensive accelerometers in the greater Pasadena area. Able to measure both weak and strong ground movement along three axes, these accelerometers ...
