The objective of the present book, which tries to summarize in an edited format and in a fairly comprehensive manner, many of the recent technical research accomplishments in the area of Smart Actuators and Smart Sensors, is to combine researchers and scientists from different fields into a single virtual room.
In the last decades, the Shape Memory Alloys, with their peculiar thermo-mechanical properties, high corrosion and extraordinary fatigue resistance, have become more popular in research and engineering applications. This book contains a number of relevant international contributions related to their properties, constitutive models and numerical simulation, medical and civil engineering applications, as well as aspects related to their processing.
The mechanical bypass uses a slotted rod that is actuated by a lever on the large dashpot plunger
shaft to provide another leakage path in the dashpot. The lever is positioned so that the bypass
opens at a gate position above speed no load, when the unit is normally on line. If it is necessary
to operate isolated, the bypass arm is moved out of the way and the unit dashpot will function
The solenoid operated dashpot bypass provides a leakage path in the dashpot when the solenoid
is energized. The rate of leakage is...
Ferroelectricity has been one of the most used and studied phenomena in both scientific
and industrial communities. Properties of ferroelectrics materials make them particularly
suitable for a wide range of applications, ranging from sensors and actuators
to optical or memory devices. Since the discovery of ferroelectricity in Rochelle Salt
(which used to be used since 1665) in 1921 by J. Valasek, numerous applications using
such an effect have been developed.
