The consumption of honey has increased manifolds in the last few decades that has led to various adulteration practices. Presently, honey is amongst the top three most adulterated food items worldwide. Honey adulterants are substances that are added to pure honey to increase its quantity such as cheap sugar, commercial syrups, etc. Since it is sold in packed jars or bottles, it is very difficult to assess the purity of commercial honey. For the proposed project, we plan to design a completely passive sensor system that can be printed on the bottle or jar containing the honey, so that it can detect honey adulteration in a wireless fashion, without opening the container. The sensor will be printed through our custom optically transparent silver nano-wire ink. The sensor will be designed such that it exhibits a unique electronic signature when illuminated with the interrogating electromagnetic signal. In case of adulteration in honey, the electronic signature will change and this deviation will help in estimating the adulteration level. In this project, students will be trained in the following three aspects. EM Simulations: They will be trained on industry-standard EM simulators (CST and HFSS) for designing the chipless electronic tags structures. Printing: They will be trained on inkjet and screen printing of electronics for fabricating the designed chipless sensor. Measurements: They will be trained to use state-of-the-art technology for measuring the performance of the built structure, this includes anechoic chamber and vector network analyzers, etc.
