PDMS micro-sensors coated onto an electrical wire are used to measure dynamic temperature variation at cryogenic range based on optical whispering-gallery mode (WGM) frequency shift principle. We designed a lab cryogenic cell via filling liquid nitrogen to create a stable low temperature down to 95K. The electrical wire is current carrying to simulate a working electrical/electronic component/d...

The current generation is witnessing a huge interest in optical waveguides due to their salient features: they are of low cost, immune electromagnetic interference, easy multiplex, have compact size, etc. These features fibers make them useful tool for various sensing applications including medicine, automotives, biotechnology, food quality control, aerospace, physical and chemical monitoring. ...
