Textile-Based Printable Electrodes for Electrochemical Sensing

Detailed Technology Description

UC San Diego researchers have developed thick-film amperometric and potentiometric sensors that are screen-printed directly on textiles. The sensors exhibit electrochemical and mechanical properties that enable their use in clothing-integrated healthcare, sports, military, security, environmental, and other related applications. Early proof of concept has been accomplished with carbon electrodes printed on elastic waistbands of underwear: these tested favorably in the laboratory for electrochemical performance under various conditions of deformation (folding, stretching, sticking). Such elastic-band-based sensors can, for example, be used in direct sweat monitoring of alcohol consumption in drivers or performance/stress of soldiers/athletes. More generally, the printed sensors will be incorporated into biocomputing systems that can make autonomous diagnoses and administer drugs based on specific combinations of biomarkers. The invention provides printing protocols and ink formulations and viscosities tailored for specific substrate textile materials to optimize printing quality, electrochemical sensor performance, and mechanical robustness.
