Design, Fabrication and Testing of Chewing Gum-Based Electronic Components and Sensors

Modern trends in many industrial sectors and shortage and high prices of classical electronic components has imposed the necessity for creating electronic components from the materials which we used every day. Such a type of material is a chewing gum. This paper presents the process of design, manufacturing and testing of the resistor, capacitor and inductor from a commercial chewing gum as it is bought. Electrical parameters were measured using an Impedance analyzer in the frequency range from 100 Hz to 40 MHz. Moreover, from recycled and reused chewing gum as a substrate, we fabricated antenna using aluminum foil as a conductive layer. The force sensor was also created based on capacitive principle where dielectric layer was reused chewing gum and gold and aluminum layer were used as conductors. The results presented in this paper contribute to the creation of an alternative kit for chewing gum-based electronics with potential applications in oral cavity and biomedicine.
