摘要

本文设计并制作了一种能够探测爆炸颗粒的微机电系统(MEMS)传感器阵列。该阵列由12根硅梁组成,每根梁上有一个加热器和一个温度传感器。AH硅束可以通过加热器加热到特定炸药的熔点,而每个传感器用于测量爆炸颗粒在熔化时吸热引起的每束温度变化。实验结果表明,该阵列能够检测小至1/spl μ /g的三硝基甲苯(TNT)和环三甲基三胺(RDX)样品。

A MEMS sensor array for explosive particle detection
In this work, a micro-electro-mechanical system (MEMS) sensor array which is capable of detecting explosive particles has been designed and fabricated. The array consists of 12 silicon beams, on each beam there are a heater and a temperature sensor. AH silicon beams can be heated up to melting point of particular kind of explosive by the heaters, while each sensor is used to measure the temperature change of each beam caused by heat absorption of the explosive particles when they melt Experimental results show that the array is capable of detecting trinitrotoluene (TNT) and cyclotrimethylenetrinitramine (RDX) samples as little as 1/spl mu/g.
