Stretchable　strain　sensors　have　the　potential　to　significantly　advance　electronic　healthcare　(E-healthcare).　However,　current　challenges,　including　a　limited　detection　range,　low　sensitivity,　aggregation　of　conductive　nanoparticles,　and　the　inherent　rigidity　of　conductive　polymers　within　hydrogel　matrices,　hinder　their　progress.　In　our　study,　we　employed　a　dual　approach:　we　tailored　both　physical　and　chemical　bond　densities　and　coupled　them　with　conductive　polymer　nanoparticles.　As　a　result,　we　developed　a　stretchable　hydrogel　strain　sensor　embedded　with　a　quick　response　code.　This　innovation　achieved　an　impressive　detection　range　of　up　to　1500%　and　a　high　gauge　factor　of　16.6.　By　modifying　the　hydrogen　bond　strength　and　converting　conductive　polymer　nanoparticles　into　linear　polymer　chains,　we　managed　to　enhance　the　sensor＇s　stretchability　to　2100%.　Moreover,　the　incorporation　of　a　quick　response　code　enabled　the　sensor　to　simultaneously　monitor　in　real-time　and　encode　information.　Thus,　our　sensor　emerges　as　a　robust　contender　for　pioneering　advancements　in　E-healthcare,　potentially　supporting　intricate　applications　like　rehabilitation　progression　tracking.
