The inverse or reverse piezoelectric effect can be defined as, whenever the piezoelectric-effect is reversed. This can be formed by applying electrical energy to make a crystal expand. The main function of this effect is to convert electrical energy into mechanical energy.

The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field.

The piezoelectric effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. There are two types of piezoelectric effects: Direct and converse effect.

An applied voltage to a piezoelectric material can cause a change of the dimensions of the material, thereby generating a motion. Lippmann predicted this inverse piezoelectric effect and the Curie brothers were the first to experimentally demonstrate it.

2022年11月2日 · The transmitter uses inverse piezoelectric effect, which is when the transmitter will use voltage to help it send out a sound wave. Once the sound wave hits an object, it will bounce back.

1.the direct piezoelectric effect – the production of electricity when stress is ap-plied, 2.the converse piezoelectric effect – the production of stress and/or strain when an electric field is applied. (For example, lead zirconate titanate crystals will exhibit a maximum shape change of about 0.1% of the original dimension.)

For actuators, the inverse piezoelectric effect was applied with the development of special ceramic materials. Materials for piezoelectric actuators are PZT (lead-zirconium-titanate). For the electrostrictive effect the materials used are PMN (lead-magnesium-niobate).

The condition for the inverse piezoelectric effect in polymers is discussed and a thermodynamic criteria is derived, The resulting expression is related to the electrical configuration of the polymer and several promising structures are proposed, A dynamical model of the piezoelectric effect is

Piezoelectric material is such that when it is subjected to a mechanical load, it gen-erates an electric charge (see Fig. 1.1(a)). This effect is usually called the “piezo-electric effect”. Conversely, when piezoelectric material is stressed electrically by a voltage, its dimensions change (see Fig. 1.1(b)). This phenomenon is known as the
