Sensing and simulation of self-inductance of a flat, circular coil in the presence of four water-based nanofluids

Inductive sensors (ISs) are extremely sensitive sensing platforms that offer high resolution and currently serve as a relatively popular platform for the detection of metals, nonmetals, semiconductors. However, in spite wonderful usability, there is startling lack IS implementation chemical sensor. Similarly, nanofluids (NFs) have gained more traction past decade since physical properties base fluids become heightened with addition nanoparticles (NPs). Regardless these advantages, both areas studies regarding behavior NFs under magnetic field (B-field). We show how novel technique using high-resolution, non-invasive inductance-to-digital converter (LDC) sensor used to detect different varying properties. The LDC proves highly capable not only serving an accurate precise but also allowing us determine exposing several inductor's B-field affects particle solution low signal concentration limits. four NF systems contain diamond, rutile, magnetite, gold NPs where demonstrated superior sensitivity gold-enhanced NFs. This exciting finding followed expected theoretical trends based on Faraday's laws magnetism, experimental results were validated finite element simulations within less than 1.0% error.
