In sensor systems, most sensors are single-point detection, and it is challenging to develop a multi-point where multiple points can be sensed. This work reports low-cost relative humidity (RH) relying on intensity-variation based the side coupling technique using polymer optical fiber, three integrated into single illuminating fiber. The structure contains twisting of two fiber times coated with agarose-gel, while rise in causes change refractive index (RI) between twisted fibers....
Abstract Fast drug-dissolving systems have been introduced to mediate the drugs which are difficult swallow or having poor water solubility. Rizatriptan benzoate is a drug recommended for patients of migraine effect one out every 5 women and 15 men globally. But least bioavailability (40%–50%) reduced on set action always increases demand carrier in order overcome these limitations. Here pullulan mediated fast was developed by using rizatriptan as model drug. While loaded nanofiber mat...
This article highlights an intensity variation-based force sensor for polymer optical fiber (POF) that relies on the twisting structure.
