TL;DR: In this article, a resonance based optical fiber sensor using a transparent conducting oxide (TCO) coating as the SPR supporting layer is presented, which shows high repeatability and a sensitivity in the order of 0.0003 RIU per nm.

TL;DR: In this article, conductive polypyrrole (PPy) coatings have been fabricated onto Au and Pt coated alumina substrates by means of the in-situ polymerization technique, and the response of the coatings to different gases and volatile organic compounds (VOCs) such as ethanol, acetone, methylamine or isopropanol and gases has been tested using the Kelvin probe (KP) setup.

TL;DR: In this article, the authors report recent developments in the design and fabrication of molecularly self-assembled thin film materials that may be incorporated with optical fiber waveguides to form humidity and other gas sensors of use in biomedical diagnositc systems.

TL;DR: A method is proposed to determine lifetime of luminescent emissions based on the phase shift measurement employing the digitalized Lissajous representation, showing an improved accuracy and repeatability.

TL;DR: In this paper, an optical waveguide coated by a thin film affects the propagation of the light generating a type of resonances called lossy mode resonances (LMR), very interesting for sensing purposes.
