Mechatronics
The term mechatronics is used to denote a rapidly developing, interdisciplinary field of engineering dealing with the design of products whose function relies on the integration of mechanical and electronic components coordinated by a control architecture.
The word mechatronics was coined in Japan in the late 1960s, spread through Europe, and is now commonly used in the United States.

Measurement Systems
The transducer is a sensing device that converts a physical input into an output, usually a voltage.
The signal processor performs filtering, amplification, or other signal conditioning on the transducer output.
The term sensor is often used to refer to the transducer or to the combination of transducer and signal processor.
Finally, the recorder is an instrument, a computer, a hard-copy device, or simply a display that maintains the sensor data for online monitoring or subsequent processing.
