A transducer is a device which transforms one type of energy into another, devices which translate an input of mechanical energy into equivalent electrical signals for
measuring and/or controlling the input phenomena. The resistance strain gage, because of its unique operational characteristics, has dominated the transducer field for the past twenty years or so.
Transducers can be, and are, based on many different operating principles - resistive, inductive, capacitive, piezoe ....etc

Composites of shape memory alloys (SMA) with a matrix have been widely studied to suppress the propagation of damage. In these studies, the SMA is used as an actuator. A multi-functional SMA as both sensor and actuator is suitable for constructing intelligent material, such as a material with a sensing and suppressing function. The damage of materials is related to the amount of strain. We studied the use of SMA wire parts as sensors to measure the amount of strain for damage estimation. The acoustic emission (AE) signals induced by phase tran ....etc

STANDARD
A standard is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
Standards are the fundamental reference for a system of weights and measures, against which all other measuring devices are compared
The ideal standard is independently reproducible without uncertainty
Any system of measurement must be related to a known standard otherwise the measurement has no meaning
BASIC CLASSIFICATION OF STANDARDS
PRIMARY STANDARDS:
It is prepared under the most ....etc
