Abstract

Polyethylene terephthalate (PET) is commercially being used for making food containers, soft drink bot- tles, etc., and is one of the large contributors to municipal solid waste. One of the solutions to address this issue is the use of recycled PET in some high-end products which may add value to this waste. This study focuses on using primarily recycled PET which has been used to 3D print substrates with fused deposition modeling set up for fabrication of sensors. In this study, after ascertaining the rheological, mechanical, and morphological properties of selected PET waste, a ring resonator was fabricated followed by the fabrication of 3D printed substrates of various infill densities (33%, 50%, 100%). Further vector network analyzer was used to explore sensing capabilities of prepared microchip antenna. The results obtained for recycled PET were com- pared (at 100% infill density) based upon dielectric constant (εr) as 2.34, with commercial thermoplastics (such as acrylonitrile butadiene styrene (ABS) (εr 2.59), ninja flex (εr 2.90), and nylon (εr 1.02). The result of the study outlined that recycled PET-based sensors are one of the suitable alter- natives for better sensing applications.
