Additively Manufactured Flexible Hybrid Capacitors and Antennas for Biosensing and RF Applications
Abstract
This presentation explores advancements in additively manufactured flexible hybrid electronics (FHE) with applications in both biosensing and RF technologies. The talk will focus on developments from the SEMI-FlexTech-funded collaboration between NoiseFigure Research and the University of Washington, Seattle, aimed at high-density multilayer printing for flexible hybrid electronics. Key advancements in electrohydrodynamic inkjet printing of rectennas, dendrite antenna arrays, and capacitors will be presented, along with their implications for RF applications. Finally, the insights gained from the additive manufacturing of the dendrite antenna arrays and capacitors will be examined in the context of enhancing the existing form-factor of the blood clotting assessment biosensor. This discussion will highlight how leveraging advancements in additive manufacturing can transform the blood clotting assessment biosensor into a standalone, flexible hybrid device with improved form factor, with an intent to serve as a broader framework for flexible bioelectronics with enhanced adaptability.
