Abstract

In this paper, we demonstrate a woven electrochemical biosensor patch as a low cost, robust wearable sensor for non-invasive diagnostics. The critical requirement for wearable sensors is their robustness which necessitates the output signal to be independent of the deformation that the sensor system could potentially undergo. In this work, the performance of woven electrode patch post standard deformations such as bending and twisting were analysed using chronoamperometric detection of lactate, a sweat borne analyte, as a model system. In spite of rigorous deformation, the CV was well within 13 %, indicating the applicability of woven electrode patch as a low cost, robust, wearable, non-invasive electrochemical biosensor platform.
