摘      要：Sensor platforms that exploit the fibrous textile threads as substrates offer great promise since they can be directly sewn,woven or stitched on to any *** can also be placed directly in intimate contact with the *** this work,we present a thread-based sensing platform in the form of a multiplexed sensing patch for continuous simultaneous on-skin monitoring of *** patch performs real-time,on-body measurements of important biomarkers present in sweat such as electrolytes(sodium and ammonium ions),metabolites(lactate)and acidity(pH).Flexible threads coated with conductive inks were used as sensing *** potentiometric detection of electrolytes and pH was made possible through ion-selective membrane deposition and pH-sensitive polyaniline coating on threads,*** amperometric enzymatic sensing scheme with lactate oxidase was used for the detection of *** array of the thread sensors is integrated onto a patch with connectivity to a miniaturized circuit module containing a potentiostat,microprocessor and wireless circuitry for wireless smartphone *** in vitro validation and an in vivo human pilot study involving a maximal exertion test show the promise of this platform for real-time physiological monitoring of human performance/fitness under stress,as well as diagnostic monitoring through sweat analysis.
