On Comparison of 3D-Printed ABS and PVDF-Based Sensors for Body-Centric Utility

The 3D-printed MPA of 1 degrees recycled PVDF and ABS provides an option to develop greener sensors for various engineering applications. But hitherto little has been reported on the comparison of 3D-printed 1 degrees recycled ABS and PVDF-based sensors for body-centric utility in the vicinity of 2.45 GHz. This study highlights the comparative analysis of 1 degrees recycled ABS and PVDF sensors (based on mechanical, piezoelectric, and RF characterization). The study suggests that 1 degrees recycled PVDF (having epsilon(r) 2 and tan delta 0.005)-based sensors have multiband resonance at 2.45 GHz, 5 GHz, and 5.5 GHz with appreciable return loss as compared to ABS (epsilon(r) 3 and tan delta 0.001). For body-centric utility (wearability in terms of SAR value (0.22 W/kg for PVDF and 0.642 W/kg for ABS at 2.45 GHz) and flexibility), 1 degrees recycled PVDF sensor was observed better than 1 degrees recycled ABS. Overall due to better piezoelectric (d(33) 0.5 pC/N), mechanical (MOT 18.30 MPa), and RF characteristics, 1 degrees recycled PVDF-based sensors may be considered a better solution for flexible and pressure-sensitive body-centric applications.
