Masks and filters are worn over the head or face in order to protect individuals from exposure to toxic chemical vapors. In these devices, there is no convenient or effective way to tell whether the adsorbent in the mask is fresh or used. A sensor that could fit inside the protective sorbent bed and tell the remaining useful lifetime of the filter would be ideal. In this work, a micropower microsensor is designed and fabricated. This sensor can fit inside a carbon adsorbent bed and tell whether the filter is operating properly or whether it is used and hazardous vapors are penetrating the protective device. The sensor is designed into a cannister filter and the feasibility of an advanced respiratory protective device that can alert the user when it is no longer effective is assessed.

口罩和过滤器戴在头上或脸上，以保护 个人暴露于有毒化学蒸汽。 在这些装置中， 没有方便或有效的方法来判断吸附剂是否 面膜是新鲜的还是用过的。 一个传感器，可以安装在保护 吸附剂床，并告诉剩余的有用寿命的过滤器将是 理想. 在这项工作中，微功率微传感器的设计和制作。 这 传感器可以安装在碳吸附床内，并告诉过滤器是否 是否正常运行或是否使用，以及是否存在危险蒸汽 穿透保护装置。 将该传感器设计成筒式滤波器，并对该滤波器的可行性进行了分析。 先进的呼吸保护装置，可以提醒用户，当它是 已不再有效。
