超声波指向性强,能量消耗缓慢,在介质中传播的距离较远,因而超声波经常用于距离的测量,如测距仪和物 位测量仪等都可以通过超声波来实现。利用超声波检测往往比较迅速、方便、计算简单、易于做到实时控制,并且在测量精度方面能达到工业实用的要求,因此在移 动机器人的研制上也得到了广泛的应用。.

原理简述: 。.

Ultrasonic sensors are made using ultrasonic sensors developed properties. Ultrasound is a mechanical vibration frequency than sound waves, the transducer excitation voltage of the chip in place under vibration generated, it has a high frequency, wave length, diffraction is small, especially the good direction, to be the ray and the orientation communication and so on. Of ultrasound on liquid, solid penetration ability is high, particularly opaque solids in the sun, which can penetrate tens of meters deep. Ultrasonic encountered impurities or the interface will form a significant reflection reflection into echo, moving objects can produce hit the Doppler effect.因此超声波检测广泛应用在工业、国防、生物医学等方面以超声波作为检测手段,必须产生超声波和接收超声波。完成这种功能的装置就是超声波传感器,习惯上称为超声换能器,或者超声探头。.

i-mu: ILoveMusic. .

其实这一切都源于“i-mu(ILoveMusic的简写,中文名:幻响)”这种全新的音频产品,这款外观极其前卫时尚的小东西能让桌子等硬材质平面唱出动听的音乐,而且音质达到了相当的品质。i-mu不属于音响或者音箱,它是别具一格的全新音频产品。它体积很小,可以方便地为CD、手提电脑、音乐手机、MP3、MP4、CD、掌上游戏机等便携设备提供优质音频。.

i-mu is a fantastic audio equipment, it is completely different from the use of electromagnetic voice coil speaker traditional voice equipment. It allows any such as: wooden desk, glass, floor, metal surface, such as flat enjoy running sweet music, so you can listen to a variety of materials around the quality of the different interpretations of the music, enjoy the fun experience of independent music. Principle of this new voice will bring you a new music lifestyles, caused a revolution in the audiovisual field. .

Co-powered vehicles and electric vehicles and other international safety standards, has basically decided by Japanese standards. To develop safety standards for electric vehicles and other specialized agencies of the United Nations global standards, "Harmonization of Vehicle Regulations World Forum (WP29)" The Crash Safety Working Group "GRSP", held in December 2009 the 46th meeting, adopted international safety standards for electric vehicles amendment. Although the body of the amendment proposed by an international Automobile Manufacturers Association (OICA), but details of the amendment point of view, basic copy of the November 2007 Japan's Ministry of Land, released * Japanese safety standards. .

  有意见认为,关于电动车辆尤其是电动汽车,新兴市场国家等制造的低价位车型将席卷全球市场。但要达到此次通过的修正案的要求,必须拥有相当的技术诀窍和技术能力。日本汽车工业会的人士表示,“此次最大的成果是在确保安全性方面前进了一步,在此基础之上,还有利于提高日本电动车辆的国际竞争力”。.


Manufacture of fine piezoelectric ceramic components, usually made of piezoelectric ceramics clear requirements. Piezoelectric ceramics because of the quality of the components have a decisive impact. Therefore, discussion and understanding of piezoelectric ceramic components, we must first understand the performance parameters of piezoelectric ceramics and measurement methods. .

压电陶瓷除了具有一般介质材料所具有的介电性和弹性性能外,还具有压电性能。压电陶瓷经过极化处理之后,就具有了各向异性,每项性能参数在不同方向上所表现的数值不同,这就使得压电陶瓷的性能参数比一般各向同性的介质陶瓷多得多。压电陶瓷的众多的性能参数是它被广泛应用的重要基础。.

一般的来讲,清洗五金、机械、汽摩、压缩机等行业的清洗多采用28KHZ频率的超声波清洗机。光学光电子清洗、线路板清洗等多采用40KHZ的频率,高频超声清洗机适用于计算机,微电子元件的精细清洗,兆赫超声清洗适用于集成电路芯片、硅片及波薄膜的清洗,能去除微米、亚微米级的污物而对清洗件没有任何损伤。For a number of precision cleaning (such as LCD, semiconductor, etc.) applications, the use of traditional cleaning frequency not only can not meet demand, but also may cause damage to the workpiece. The most typical example is on military electronics, the industry has expressly permitted the use of traditional frequency (20 ~ 30KHz) of the ultrasonic cleaner. In fact, in some of Europe and the United States, Japan and other developed countries, has been selected frequency through the washing machine (80KHz or more frequencies, and some have reached the 200K or 400K) to make this issue has been resolved. .


PZT作为一种性能优异的铁电材料,具有良好的介电、铁电、压电、热释电等效应,早已应用于非挥发性动态随机存储器的制作,在电子材料中具有重要地位。.

In recent years, with the rapid development of micro-electromechanical systems, PZT ferroelectric thin films because it had the high-voltage constant and high electromechanical coupling coefficient and other advantages and Shoudao the Da Jia's Pubianchongshi, are widely used in Weixing sensors and micro-drives, such as: mirror , micro piezoelectric cantilever, micro-motors, such as the production of micro-accelerometers, micro-electromechanical systems has become the most widely used sensor and driver materials. .

然而必须注意的是,将PZT薄膜应用于不同场合,对薄膜压电、介电、铁电以及其它性能有着不同要求。例如对于高频和超高频器件,要求薄膜介电常数和高频损耗小;滤波器要求薄膜谐振频率稳定性好,机械品质因数高;而微型驱动器则要求薄膜的压电性能优异。因此,性能表征对于系 。.
