9、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HONY WELL公司ST-3000 型智能传感器，芯片尺寸才有3 × 4 × 2mm3，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。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

10、传感器(Smart Sensor ) ，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。附件 2：外文原文Development of Sensor New TechnologySensor is one
