Accelerometers

Definition : Devices designed to measure the rate of change of an object's velocity. These devices typically consist of a sensor and transducer, an amplifier, and extension cables for connection to an electronic measuring unit. They work on the principle of seismic mass: this mass is restrained by a spring, and when the transducer case is accelerated, the mass moves relative to the case and exerts a force on the spring. The acceleration is calculated by measuring mass displacement or the mass' force on the spring, converted to an electrical signal. Acceleration transducers are available using strain gauges (e.g., metallic foil, piezoresistive), capacitive elements, and piezoelectric elements. Clinical accelerometers are intended for several purposes, including measuring the acceleration of body parts to assess a patient's mobility and/or activity (alone or as a component of activity monitors and gait analyzers respectively); assess tremor (e.g., in patients with Parkinson's disease); and activate pacemakers according to the patient's position (e.g., upright).
