A Simple and Scalable Fabrication Method for Organic Electronic Devices on Textiles Usein Ismailov1, Esma Ismailova1, Seiichi Takamatsu2 1Department of Bioelectronics, Ecole Nationale Supérieure des Mines de Saint-Étienne, CMP-EMSE, MOC, 2Graduate School of Frontier Sciences, The University of Tokyo In this paper, we present a protocol to selectively deposit organic materials on textiles, which allows for the direct integration of organic electronic devices with wearables. The fabricated devices can be fully integrated in textiles, respecting their mechanical appearance and enabling sensing capabilities.
Wicking Tests for Unidirectional Fabrics: Measurements of Capillary Parameters to Evaluate Capillary Pressure in Liquid Composite Molding Processes Monica Francesca Pucci1, Pierre-Jacques Liotier1, Sylvain Drapier1 1Department of Mechanics and Materials Processing, George Friedel Laboratory, Mines Saint-Étienne An experimental method to measure geometrical parameters and the apparent advancing contact angles describing capillary wicking in unidirectional synthetic and natural fabrics is proposed. These parameters are mandatory for the determination of the capillary pressures that must be taken into account for liquid composite molding (LCM) applications.
Sensing of Barrier Tissue Disruption with an Organic Electrochemical Transistor Scherrine A. Tria1, Marc Ramuz1, Leslie H. Jimison2, Adel Hama1, Roisin M. Owens1 1Department of Bioelectronics, Ecole Nationale Superieure des Mines, 2Research and Exploratory Development Division, Applied Physics Laboratory, Johns Hopkins University The Organic Electrochemical Transistor is integrated with live cells and used to monitor ion flux across the gastrointestinal epithelial barrier. In this study, an increase in ion flux, related to disruption of tight junctions, induced by the presence of the calcium chelator EGTA (ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetra acetic acid), is measured.
