The PolySense team has just published a new article on Applied Science reporting on a study of the front-end electronics for quartz tuning forks (QTFs) employed as optoacoustic transducers in quartz-enhanced photoacoustic spectroscopy (QEPAS) sensing. We demonstrated that the
fully dierential voltage amplifier allows for a nearly doubled SNR with respect to the typically used single-ended transimpedance amplifier.
