摘要

介绍了用于遥控释药胶囊的微点火电路设计。采用微气体传感器中的膜式结构

通过有限元分析工具ANSYS 12.1对不同参数的点火电路进行仿真

分析比较了不同点火电阻器线宽和间距的温度场分布

当点火电阻器的线宽为20μm、间距为10μm时

中心有效区域的温度分布比较均匀且功耗最低。当点火时间为0.05 s

点火温度为375℃

点火功率为20 mW时

结果表明:设计的微点火电路功耗低至20 mW

满足了低功耗的要求

提高了遥控释药胶囊的整体性能。

Abstract

A micro-ignition circuit design of remote controlled capsule is described.The micro-ignition circuit utilizes the membrane structure of micro-structure gas sensor.The temperature field distribution with different width and distance through the finite element analysis tool ANSYS 12.1 are analyzed and compared.When the width and distance of ignition resistance are designed as 20 μm and 10 μm

the result shows that the center of the active area temperature distribution is uniform and the power consumption is the lowest.When the ignition time is 0.05s and the ignition temperature is 375 ℃

the ignition power is only 20 mW.The results show that the power consumption of the micro-ignition circuit can be reduced to 20 mW.It meets requirements of low power consumption and improves the overall properties of remote controlled capsule.
