An innovative sensing tube with an integrated piezoelectric flow sensor to measure flow rate in portal vein during liver transplantation has been developed and characterized in this work. This smart tube aims to measure flow rates in the portal vein in a real-time continuous format with high reliability. The PVDF-TrFE piezoelectric flow sensor integrated in a tube was able to measure flow rates with...
In this paper, a new mold-transfer method to pattern piezoelectric polymer has been developed and applied to fabricate innovative dome and bump shape polyvinylidene-fluoride-trifluoroethylene (PVDF-TrFE) films. The dome and bump shape PVDF-TrFE films have been successfully fabricated and characterized as a sensing component for flexible tactile sensors. The tactile sensors developed using these polymer...
Piezoelectric copolymer, PVDF-TrFE, diaphragm arrays with integrated microfluidic chip for high performance protein immunosensors were developed and characterized in this work. Mold-transfer and hot-embossing techniques provide a high throughput and repeatable way to fabricate piezoelectric polymer diaphragms and PVDF-TrFE's hydrophobic surface acts as a natural bioreceptor to capture proteins of...
