克服交叉灵敏度的限制：化学电阻式气体传感器阵列的模式识别方法。

作为人工嗅觉的信息采集终端，化学电阻式气体传感器常常受到交叉敏感性的困扰，降低其对环境气体的交叉反应一直是气体传感领域的难点和重点。基于传感器阵列的模式识别是克服气体传感器交叉敏感性的最显著方法。选择合适的模式识别方法对于加强数据分析、减少误差、提高系统可靠性、获得更好的分类或气体浓度预测结果至关重要。在本综述中，我们分析了化学电阻式气体传感器交叉灵敏度的感应机制。我们进一步研究了气体传感阵列中使用的模式识别算法的类型、工作原理、特点和适用的气体检测范围。此外，我们还报告、总结和评估了用于气体识别的模式识别方法的突出和新进展。同时，本研究还展示了利用这些方法进行气体识别的最新进展，特别是在确保食品安全、监测环境和辅助医疗诊断这三个关键领域。总之，本研究通过考虑现有的情况和挑战，预测了未来的研究前景。希望这项工作能为减轻气敏设备的交叉敏感性做出积极贡献，并为气体识别应用中的算法选择提供有价值的见解。
