外文翻译(中文)

传感器是一种能将物理量、化学量、生物量等转换成电信号的器件。输出信号有不

同形式,如电压、电流、频率、脉冲等,能满足信息传输、处理、记录、显示、控制要

求,是自动检测系统和自动控制系统中不可缺少的元件。如果把计算机比作大脑,那么

传感器则相当于五官,传感器能正确感受被测量并转换成相应输出量,对系统的质量起

决定性作用。自动化程度越高,系统对传感器要求越高。在今天的信息时代里,信息产

业包括信息采集、传输、处理三部分,即传感技术、通信技术、计算机技术。现代的计

算机技术和通信技术由于超大规模集成电路的飞速发展,而已经充分发达后,不仅对传

感器的精度、可靠性、响应速度、获取的信息量要求越来越高,还要求其成本低廉且使

用方便Q显然传统传感器因功能、特性、体积、成本等已难以满足而逐渐被淘汰。世界

许多发达国家都在加快对传感器新技术的研究与开发,并且都已取得极大的突破。如今

传感器新技术的发展,主要有以下几个方面:一、发现并利用新现象

利用物理现象、化学反应、生物效应作为传感器原理,所以研究发现新现象与新效

应是传感器技术发展的重要工作,是研究开发新型传感器的基础。日本夏普公司利用超

导技术研制成功高温超导磁性传感器,是传感器技术的重大突破,其灵敏度高,仅次于

超导量子干涉器件。它的制造工艺远比超导量子干涉器件简单。可用于磁成像技术,有

广泛推广价值。

利用抗体和抗原在电极表面上相遇复合时,会引起电极电位的变化,利用这一现象

可制出免疫传感器。用这种抗体制成的免疫传感器可对某生物体内是否有这种抗原作检

查。如用肝炎病毒抗体可检查某人是否患有肝炎,起到快速、准确作用。美国加州大学

巳研制出这类传感器。

二、利用新材料

传感器材料是传感器技术的重要基础,由于材料科学进步,人们可制造出各种新型

传感器。例如用高分子聚合物薄膜制成温度传感器;光导纤维能制成压力、流量、温度、

位移等多种传感器;用陶瓷制成压力传感器。高分子聚合物能随周围环境的相对湿度大

小成比例地吸附和释放水分子。高分子电介常数小,水分子能提高聚合物的介电常数。

将高分子电介质做成电容器,测定电容容量的变化,即可得出相对湿度。利用这个原理

制成等离子聚合法聚苯乙烯薄膜温度传感器,其有以下特点:

测湿范围宽;

温度范围宽,可达-400C〜+1500℃;

响应速度快,小于1S;

尺寸小,可用于小空间测却话巴山夜雨时上一句是什么 湿;

温度系数小。

陶瓷电容式压力传感器是一种无中介液的干式压力传感器。采用先进的陶瓷技术,

厚膜电子技术,其技术性能稳定,年漂移量小于0.1%F∙S,温漂小于0.15%∕10K,抗

过载强,可达量程的数百倍。测量范围可从0到60mpa。德国E+H公司和美国Kavlio公

司产品处于领先地位。

光导纤维的应用是传感材料的重大突破,其最早用于光通信技术。在光通信利用中

发现当温度、压力、电场、磁场等环境条件变化时,引起光纤传输的光波强度、相位、

频率、偏振态等变化,测量光波量的变化,就可知道导致这些光波量变化的温度、压力、

电场、磁场等物理量的大小,利用这些原理可研制出光导纤维传感器。光纤传感器与传

统传感器相比有许多特点:灵敏度高,结构简单、体积小、耐腐蚀、电绝缘性好、光路

可弯曲、便于实现遥测等。光纤传感器日本处于先进水平。如IdeCIZUmi公司和Sunx

公司。光纤传感受器与集成光路技术相结合,加速光纤传感器技术的发展。将集成光路

器件代替原有光学元件和无源光器件,使光纤传感器有高的带宽、低的信号处理电压,

可靠性高,成本低。三、微机械加工技术

半导体技术中的加工方法有氧化、光刻、扩散、沉积、平面电子工艺,各向导性腐蚀

及蒸镀,溅射薄膜等,这些都已引进到传感器制造。因而产生了各种新型传感器,如利

用半导体技术制造出硅微传感器,利用薄膜工艺制造翁卷的乡村四月古诗意思 出快速响应的气敏、湿敏传感器,

利用溅射薄膜工艺制压力传感器等。

日本横河公司利用各向导性腐蚀技术进行高精度三维加工,制成全硅谐振式压力传

感器。核心部分由感压硅膜片和硅膜片上面制作的两个谐振梁结成,两个谐振梁的频差

对应不同的压力,用频率差的方法测压力,可消除环境温度等因素带来的误差。当环境

温度变化时,两个谐振梁频率和幅度变化相同,将两明朝四大才子 个频率差后,其相同变化量就能够

相互抵消。其测量最高精度可达0.01%FSQ

美国SiliconMicrostructureInC.(SMl)公司开发一系列低价位,线性度在0.

1%到0.65%范围内的硅微压力传感器,最低满量程为0.15psi(IKPa),其以硅为材料

制成,具有独特的三维结构,轻细微机械加工,和多次蚀刻制成惠斯登电桥于硅膜片上,

当硅片上方受力时,其产生变形,电阻产生压阻效应而失去电桥平衡,输出与压力成比例

的电信号.象这样的硅微传感器是当今传感器发展的前沿技术,其基本特点是敏感元件体

积为微米量级,是传统传感器的儿十、儿百分之一。在工业控制、航空航天领域、生物

医学等方面有重要的作用,如匕机上利用可减轻飞机重量,减少能源。另一特点是能敏

感微小被测量,可制成血压压力传感器。

中国航空总公司北京测控技术研究所,研制的CYJ系列溅谢膜压力传感器是采用离

子溅射工艺加工成金属应变计,它克服了非金属式应变计易受温度影响的不足,具有高

稳定性,适用于各种场合,被测介质范围宽,还克服了传统粘贴式带来的精度低、迟滞

大、蠕变等缺点,具有精度高、可靠性高、体积小的特点,广泛用于航空、石油、化工、

医疗等领域。

四、集成传感器

集成传感器的优势是传统传感器无法达到的,它不仅仅是一个简单的传感器,其将

辅助电路中的元件与传感元件同时集成在一块芯片上,使之具有校准、补偿、自诊断和

网络通信的功能,它可降低成本、增加产量,美国LUCAS、NOVASENSOR公司开发的这种

血压传感器,每星期能生产1万只

五、智能化传感器

智能化传感器是一种带微处理器的传感器,是微型计算机和传感器相结合的成果,

它兼有检测、判断和信息处理功能,与传统传感器相比有很多特点:

具有判断和信息处理功能,能对测量值进行修正、误差补偿,因而提高测量精度;

可实现多传感器多参数测量;

有自诊断和自校准功能,提高可靠性;

测量数据可存取,使用方便;

有数据通信接口,能与微型计算机直接通信。

把传感器、信号调节电路、单片机集成在一芯片上形成超大规模集成化的高级智能

传感器。美国HONYWELL公司ST-3000型智能传感器,芯片尺寸才有342mm3,采用

半导体工艺,在同一芯片上制成CPU、EPROM、静压、压差、温度等三种敏感元件Q

智能化传感器的研究与开发,美国处于领先地位。美国宇航局在开发宇宙飞船时称

这种传感器为灵巧传感器(SnIartSensor),在宇宙飞船上这种传感器是非常重要的。我

国在这方面的研究与开发还很落后,主要是因为我国半导体集成电路工艺水平有限。

传感器的发展日新月异,特别是80年代人类由高度工业化进入信息时代以来,传

感器技术向更新、更高的技术发展。美国、日本等发达国家的传感器技术发展最快,我

国由于基础薄弱,传感器技术与这些发达国家相比有较大的差距。因此,我们应该加大

对传感器技术研究、开发的投入,使我国传感器技术与外国差距缩短,促进我国仪器仪

表工业和自化化技术的发展。
