Ms. Leqing Lin | Indoor Air Quality Monitoring | Best Researcher Award

Jinan University | China

Ms. Leqing Lin’s research is centered on advanced optical and photoacoustic gas-sensing technologies, with a strong emphasis on developing ultra-sensitive, compact, and real-time detection systems for environmental and industrial applications. Her work spans quartz-enhanced photoacoustic spectroscopy (QEPAS), conductance spectroscopy, hybrid conductance-photoacoustic approaches, and distributed-feedback (DFB) laser–based sensing, enabling precise detection of gases such as CO, CO₂, H₂, hydrocarbons, water vapor, and humidity at extremely low concentrations. She has made notable contributions to multi-species gas analysis by integrating acoustic and electrical detection pathways, greatly improving speed, selectivity, and sensitivity. Ms. Lin’s innovations include cost-effective hydrogen sensors based on quartz crystal tuning forks, non-contact QEPAS architectures, clamp-type tuning-fork–enhanced systems, and miniature multipass optical cells featuring novel beam-shaping designs. Her studies also extend into unconventional sensing enhancements, such as spider-silk-assisted conductance spectroscopy for improved humidity detection in medical masks. Committed to sensor miniaturization and robust field deployment, she designs compact, low-power architectures suitable for portable, wearable, or embedded platforms. Recent breakthroughs—such as her 2.3 μm DFB-laser CO sensor using MPC-LITES for real-time cigarette-smoke monitoring and a ppb-level CO₂ sensor using an eight-petaled spot-pattern multipass cell—highlight her focus on high-impact, practical gas-sensing solutions. With a growing body of publications, 99 citations, and an h-index of 5, Ms. Lin’s research is advancing the frontier of optical and photoacoustic sensing by refining detection mechanisms, hybridizing technologies, and enabling highly sensitive, cost-efficient monitoring systems for a wide range of real-world applications.
