Piezo what? The word piezoelectric originates from the Greek word piezein, which literally means to squeeze or press. Piezoelectricity is found in a ton of everyday electronic devices, from quartz watches to speakers and microphones. In a nutshell:. Piezoelectricity is the process of using crystals to convert mechanical energy into electrical energy, or vice versa.

How Piezoelectricity Works

Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals , certain ceramics , and biological matter such as bone, DNA and various proteins [1] in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0. Conversely, those same crystals will change about 0. The inverse piezoelectric effect is used in the production of ultrasonic sound waves. French physicists Jacques and Pierre Curie discovered piezoelectricity in , [6] and it has subsequently been exploited in a number of useful applications, such as the production and detection of sound, piezoelectric inkjet printing , generation of high voltages, clock generator in electronics, microbalances , to drive an ultrasonic nozzle , and ultrafine focusing of optical assemblies.

Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect the generation of electricity when stress is applied also exhibit the converse piezoelectric effect the generation of stress when an electric field is applied. When piezoelectric material is placed under mechanical stress, a shifting of the positive and negative charge centers in the material takes place, which then results in an external electrical field. When reversed, an outer electrical field either stretches or compresses the piezoelectric material. The piezoelectric effect is very useful within many applications that involve the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultra fine focusing of optical assemblies.

Consumer products, automotive electronics, medical technology, and industrial systems are but a few areas where piezoelectric components are indispensable. Besides models to describe and understand the behaviour of piezoelectric materials and components, this book gives an overview of piezoelectric materials, piezoelectric ceramic components and thin films, and the manufacturing thereof. Application areas such as sensors, generators, energy harvesters, actuators, motors and acoustic transducers are addressed. The book concludes with an overview of measurement techniques and practical tips and tricks for the use of piezoelectric components. Betase initiated the first chapter and supported the authors Jan Holterman and Pim Groen by editing the contents of the book. Here you can download the first pages of this book as PDF document.

Piezoelectric Materials for Medical Applications

We apologize for the inconvenience...

Piezoelectricity is a property of certain dielectric materials to physically deform in the presence of an electric field, or conversely, to produce an electrical charge when mechanically deformed. There are a wide variety of materials which exhibit this phenomenon to some degree, including natural quartz crystals, semi-crystalline polyvinylidene polymer, polycrystalline piezoceramic, bone and even wood. Piezoelectricity is due to the spontaneous separation of charge with certain crystal structures under the right conditions. This phenomenon, referred to as spontaneous polarization , is caused by a displacement of the electron clouds relative to their individual atomic centers, i. Such a situation produces an electric dipole. Polycrystalline ceramic, one of the most active piezoelectric materials known, is composed of randomly oriented minute crystallites. The overall effect of randomly oriented polar domains is an initial lack of piezoelectric behavior.

Сьюзан на мгновение заколебалась и оглянулась на заблокированную дверь. Всего двадцать минут, подумала. Повернувшись к терминалу Хейла, Сьюзан вдруг уловила странный мускусный запах - очень необычный для Третьего узла.

Это придает правдоподобность его электронной переписке. - Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает. - Убедительно.

Мы похороним ключ Хейла и станем молиться Богу, чтобы Дэвид нашел копию, которая была у Танкадо. Дэвид, вспомнила Сьюзан. Она заставляла себя не думать о. Ей нужно было сосредоточиться на неотложных вещах, требующих срочного решения. - Я возьму на себя лабораторию систем безопасности, - сказал Стратмор.  - Всю статистику по работе ТРАНСТЕКСТА, все данные о мутациях. Ты займешься Третьим узлом.

 - Стратмор приподнял брови, точно ждал объяснений. - Японские иероглифы. Стратмор покачал головой. - Это и мне сразу пришло в голову.

Телефон заливался еще секунд пятнадцать и наконец замолк. Джабба облегченно вздохнул. Через шестьдесят секунд у него над головой затрещал интерком. - Прошу начальника систем безопасности связаться с главным коммутатором, где его ждет важное сообщение.

Он же давал им китайские значения, потому что такую задачу они перед ним поставили. - Господи Иисусе.  - Морант закашлялся.

На такой риск вы не пойдете.

Ничего похожего. У Халохота был компьютер Монокль, мы и его проверили. Похоже, он не передал ничего хотя бы отдаленно похожего на набор букв и цифр - только список тех, кого ликвидировал. - Черт возьми! - не сдержался Фонтейн, теряя самообладание.

 Подождите, - сказала Сьюзан, заглядывая через плечо Соши.  - Есть еще кое-что. Атомный вес. Количество нейтронов.

Халохот настойчиво преследовал свою жертву. Вначале он хотел выстрелить Беккеру в голову, но, будучи профессионалом, решил не рисковать. Целясь в торс, он сводил к минимуму возможность промаха в вертикальной и горизонтальной плоскостях. Эта тактика себя оправдала. Хотя в последнее мгновение Беккер увернулся, Халохот сумел все же его зацепить.
