A quartz tuning fork (QTF) and a lithium niobate tuning fork (LiNTF) are implemented in the same light-induced thermoelastic spectroscopy experimental set-up. Both resonators demonstrate a linear response with respect to the hydrogen  concentration and a minimum detection limit (MDL) of 0.50 % and of 1.50 % at 0.1 s of integration time with the  QTF and the LiNTF, respectively. The long-term stability analysis highlights a bias instability for the QTF, mainly addressed to the inhomogeneities at the edge of the active area. Conversely, the uniform surface of the LiNTF returns a highly stable detection, allowing an MDL as low as 0.1 % at 64 s of integration time. This first  demonstration of a LiNTF as photodetector paves the way to the realization of fully integrated sensors based on lithium-niobate-on-insulator platforms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following link provides access to the article:   <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/10\/H2-Lites.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/10\/H2-Lites.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"861\" height=\"726\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/10\/H2-lites.jpg\" alt=\"\" class=\"wp-image-3601\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/10\/H2-lites.jpg 861w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/10\/H2-lites-300x253.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/10\/H2-lites-768x648.jpg 768w\" sizes=\"(max-width: 861px) 100vw, 861px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published\u00a0 a new article on Sensors and Actuators B Chemical Journal Elsevier (IF 7.7)\u00a0 reporting on a study on the H2 spectral properties and a comparison between two different piezoelectric resonators employed as infrared detectors for hydrogen sensing are reported.
