金属氧化物半导体（MOS）技术作为电子气体传感设备（电子鼻）的传感器的主要缺点之一是每次气体暴露后需要长的恢复期。这严重限制了其在气体浓度可能快速变化的应用中的使用，如机器人嗅觉的情况，其中机器人必须以非常低的速度移动，几乎与任何实际的机器人操作不兼容。本文介绍了一种新的电子鼻的设计，在很大程度上克服了这种限制。所提出的电子鼻，称为多室电子鼻（MCE鼻），包括几组相同的MOS传感器，这些传感器容纳在单独的室中（在我们目前的原型中为四个），它们在感测和恢复状态之间交替，作为一个整体，提供了一种能够感测化学浓度更快变化的设备。
One of the major disadvantages of the Metal Oxide Semiconductor (MOS) technology as transducer for electronic gas sensing devices (e-noses) is the long recovery period needed after each gas exposure. This severely restricts its usage in applications where the gas concentration may change rapidly, as it is the case of robotic olfaction, where the robot must move at a very low speed, almost incompatible with any practical robot operation. This paper describes the design of a new e-nose which overcomes, to a great extent, such limitation. The proposed e-nose, called Multi-Chamber Electronic Nose (MCE-nose), comprises several identical sets of MOS sensors accommodated in separate chambers (four in our current prototype), which alternate between sensing and recovery states, providing, as a whole, a device capable of sensing faster changes in chemical concentrations.
