PIEZOELECTRIC MATERIAL and simulation

The name “piezo” drives from a Greek word meaning “to press.”Piezoelectric materials are materials that produce an electric current when they are placed under mechanical stress. The piezoelectric process is also reversible, so if you apply an electric current to these materials, they will actually change shape slightly (a maximum of 4%). QUARTZ CRYSTAL (wikipedia) […]

What determines an objects temperature?

Temperature is a measure of the degree of hotness or coldness of an object or substance. It is a measure of the average kinetic energy of the particles in an object or substance, which is the energy associated with the movement of the particles. The higher the temperature of an object or substance, the faster […]

Skin Depth in COMSOL Multiphysics

What is skin depth ? The skin effect is the tendency for an alternating electric current (AC) to be dispersed throughout a conductor so that the current density is highest at the conductor’s surface and exponentially declines as the conductor is drilled deeper. Between the conductor’s outer surface and a depth known as the skin […]

Ferroelectric material simulation in COMSOL Multiphysics

Ferroelectric material simulation in COMSOL What are Ferroelectric Materials? Materials that demonstrate ferroelectricity are referred to as ferroelectric materials. Ferroelectricity refers to a material’s capacity to exhibit spontaneous electric polarisation, and it may be a useful property. By applying an external electric field in the opposite direction, it is possible to invert this polarisation. Polarization […]
