How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...
Inertial navigation systems use information provided by accelerometers and gyroscopes to provide the position and orientation of an object relative to a predetermined origin point, orientation and ...
A quantum device that can determine its position in three dimensions is more accurate than non-quantum versions. Vehicles could use it to navigate even if GPS stopped working. One way to keep track of ...
