To address these challenges, we present a sprayable bio\u2010inspired hydrogel (SOPB) synthesized from okra mucilage, polyvinyl alcohol, and borax, with NaCl incorporation to enhance ionic conductivity. This hydrogel shows strong adhesion, injectability, stretchability, transparency, self\u2010healing capability, passive thermal regulation, conductivity, and antibacterial activity against\n                    <jats:italic>Escherichia coli<\/jats:italic>\n                    and\n                    <jats:italic>Staphylococcus aureus<\/jats:italic>\n                    \u2014a rare combination of properties within a single material platform. Its porous, water\u2010rich network promotes efficient ion transport, while its conductivity enables stable electrochemical signaling, making it highly suitable for biosensor applications. Remarkably, the hydrogel performed comparably to commercial electrodes in surface electromyography (sEMG) and electrocardiography (ECG) measurement using Shimmer3 device. We fabricated a low\u2010cost, multilayered hydrogel\u2010based device (OKPVD device) capable of monitoring various human motions (finger, knee, and wrist bending, as well as tapping and walking) and detecting different emotional states, such as different facial expressions. Beyond sensing, the hydrogel's adaptability underscores its potential for wearable bioelectronics and skin\u2010friendly E\u2010skindevices. This work presents a facile sprayable fabrication route that integrates biomedical engineering, soft electronics, and human\u2013machine interfaces for healthcare and rehabilitation.\n
