由于脱附温度取决于蒸汽的种类，因此如果设定适合目标蒸汽的温度，则通常用于提高传感器灵敏度的预浓缩器在气味传感系统中也可以有效地增强辨别能力。因此，一个自主的系统，以调整其温度分布，根据目标气味成功地开发了使用数值优化算法。该系统是一种自适应能力强的主动传感系统。
A preconcentrator conventionally used for increasing sensor sensitivity is also effective in an odor-sensing system to enhance the discrimination capability if its temperature suitable for target vapors is set since the desorption temperature depends upon the kind of the vapor. Thus, an autonomous system to adjust its temperature profile according to target odors was successfully developed using a numerical optimization algorithm. The system is a kind of active sensing system with high capability of adaptation compared with the conventional system.
