accelerometer

Any instrument used to measure acceleration.

Typically, accelerometers contain a small mass, connected to a stiff spring, with some electrical means of measuring the spring deflection when the mass is accelerated; the type of accelerometer used in gait analysis is usually very small and measures acceleration in one direction, but can be clustered for two- and three-dimensional measurements.

accelerometer

(ak″sel-ĕ-rom′ĕ-tĕr) [ acceler(ation) + -meter]

An instrument that detects a change in the velocity of the object to which it is attached. The device may be designed to record the changes and indicate the direction(s) of the acceleration.

Caltech engineers led by Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering in the Division of Engineering and Applied Science, developed a new optical gyroscope that is 500 times smaller than the current state-of-the-art device, yet they can detect phase shifts that are 30 times smaller than those systems.
