Passive Sensors can obtain measurements only in the Day time. Analog and digital transducers. Transducers which require an external power source for their operation is called as a passive transducer. The present article provides a brief review of the open literature concerning applications of piezoelectric sensors and actuators for active and passive vibration control. stream Most transducers, however, involve electricity to perform a variety of very useful tasks. If a set of embedded transducers would be able to perform passive (AE, localization of active cracks) and active measurements (determination of changes of velocity/attenuation/material parameters) at the same time, this would be a great step forward for structural health monitoring of concrete structures. Thermocouple, Photovoltaic cell and more are the best examples of the transducers. 23 0 obj There are two types of transducers, they are: Active transducers; Passive transducers; Active transducers.
