Ferroelectrics found extensive uses in industrial applications because of their unparalleled electromechanical and electrical characteristics, for example, as actuators, sensors and capacitors [1], [2 ...

Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...

In the event of a breakdown, any number of issues may be the culprit, but there’s one in particular that’s particularly challenging to diagnose: resonance. Resonance can be a problem in any machine, ...

Piezoelectric effect is when certain solid material is compressed under mechanical stress, and it develops a voltage potential by accumulating electrical charges. French physicists Jacques and Pierre ...

Piezoresponse force microscopy (PFM) is an effective method for examining ferroelectric materials due to its nanometer-level resolution and high sensitivity, inherited from atomic force microscopy ...

Piezoelectricity is a material’s capacity to transform mechanical energy (pressing) into electric energy (polarization) and vice versa. The word “piezo” derives from the Greek word piezein, which ...

Ideal capacitors only exist in textbooks. Every real-world capacitor has additional complexity arising from its physical structure. Two plates separated by a dielectric layer are in series with wire ...
