A 3D printing technique was introduced to a quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor and is reported for the first time. The acoustic detection module (ADM) was designed and fabricated using the 3D printing technique and the ADM volume was compressed significantly. Furthermore, a small grin lens was used for laser focusing and facilitated the beam adjustment in the 3D-printed ADM. A quartz tuning fork (QTF) with a low resonance frequency of 30.72 kHz was used as the acoustic wave transducer and acetylene (C₂H₂) was chosen as the analyte. The reported miniaturized QEPAS trace gas sensor is useful in actual sensor applications.
一种3D打印技术被引入到石英增强光声光谱（QEPAS）传感器中，这是首次报道。声学检测模块（ADM）采用3D打印技术进行设计和制造，其体积显著压缩。此外，使用了一个小的平凸透镜进行激光聚焦，并便于在3D打印的ADM中进行光束调整。选用了一个低共振频率为30.72kHz的石英音叉（QTF）作为声波换能器，并选择乙炔（C₂H₂）作为分析物。所报道的小型化QEPAS痕量气体传感器在实际传感器应用中很有用。
