碳纳米管（CNT）由于其多功能特性，已被提出作为结合辐射和化学敏感性的火焰传感器。化学功能化增强了 CNT 传感器对火焰引起的任何化学修饰的敏感性。研究表明，传感器的响应取决于测量方向（纵向和横向）以及辐射强度。灵敏度与其距源的距离之间的非线性关系用于校准火焰的强度。本方法通过利用校准方案在任何特定偏置电流下操作并在特定偏置电流下相对于任何工作距离调整其灵敏度，允许更简单的火焰检测方法。
Carbon nanotubes (CNT) due to its multifunctional characteristics has been presented as a flame sensor by combining both radiation and chemical sensitivity. Chemical functionalization enhances the sensitivity of CNT sensor toward any chemical modifications that are induced by the flame. Response of the sensor is revealed to be dependent on the measurement direction (longitudinal and transverse) as well as the radiation intensity. A nonlinear relation between the sensitivity and its distance from the source is used to calibrate the intensity of the flame. The present method allows a simpler approach for the flame detection by utilizing a calibration scheme to operate at any particular bias current and tune its sensitivity with respect to any working distance at a particular bias current.
