transducer

[trans-doo´ser]

a device that translates one physical quantity to another, e.g., pressure or temperature, to an electrical signal.

neuroendocrine transducer a neuron, such as a neurohypophyseal neuron, that on stimulation secretes a hormone, thereby translating neural information into hormonal information.

pressure transducer an electronic device that converts pressure (such as blood pressure) into electrical signals that can be recorded graphically and monitored.

trans·duc·er

(tranz-dū'sĕr),

A device designed to convert energy from one form to another.

transducer

(trăns-do͞o′sər, -dyo͞o′-, trănz-)

Biology Something, such as a receptor in a cell membrane, that transmits a signal within a cell or from the exterior of a cell to its interior.

transducer

Instrumentation A device that transforms one form of energy to another–eg, a photocell that converts light into electrical energy; it is the major component in ultrasonographic devices, and contains an emitting and receiving piezoelectric crystal

trans·duc·er

(trans-dū'sĕr)

A device that converts energy from one form to another (e.g., from electrical energy into ultrasonic energy).

First, the 5 cm-wide linear-array transducer could satisfactorily image in its entirety only the cross-sectional image of the distal portion of the quadriceps (see previous section on experiments in nondisabled subjects); therefore, in the subjects with COPD, the two operators used only the 6 cm-wide curved-array transducer (5 MHz, C60x, SonoSite).
