Piezoelectric motor — A piezoelectric motor or piezo motor is a type of electric motor based upon the change in shape of a piezoelectric material when an electric field is applied. Piezoelectric motors make use of the converse piezoelectric effect whereby the material … Wikipedia
Electromechanical coupling coefficient — is a numerical measure of the conversion efficiency between electrical and acoustic energy in piezoelectric materials.Qualitatively the electromechancial coupling coefficent, k, can be determined as:: mathcal{K}^{ 2} = frac{1}{mbox{ energy… … Wikipedia
Quartz crystal microbalance — A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film… … Wikipedia
Поверхностные акустические волны в пьезоэлектриках — Генерация ПАВ с помощью встречно гребенчатого преобразователя. Справа приёмные дорожки снимают сигнал, при этом происходит обратное преобразование механической энергии в переменный электрический ток, через нагрузочный резистор. Поверхностные… … Википедия
Mechanical filter — Figure 1. A mechanical filter made by the Kokusai Electric Company intended for selecting the narrow 2 kHz bandwidth signals in SSB radio receivers. It operates at 455 kHz, a common IF for these receivers, and is dimensioned 45×15×15 mm ( … Wikipedia
Multiferroics — have been formally defined as materials that exhibit more than one primary ferroic order parameter simultaneously (i.e. in a single phase).[1] The four basic primary ferroic order parameters are ferromagnetism, ferroelectricity, ferroelasticity… … Wikipedia
