Intelligent human-machine interfaces (HMIs) integrated wearable electronics are essential to promote the Internet of Things (IoT). Herein, a curcumin-assisted electroless deposition (ELD) technology is developed for the first time to achieve stretchable strain sensing yarns (SSSYs) with high conductivity (0.2 Ω/cm) and ultralight weight (1.5 mg/cm). The isotropically deposited structural yarns can bear high uniaxial elongation (>> 1100) and still retain low resistivity after 5000 continuous stretching-releasing cycles under 50 strain. Apart from the high flexibility enabled by helical loaded structure, a precise strain sensing function can be facilitated under external forces with metal-coated conductive layers. Based on the mechanics analysis, the strain sensing responses are scaled with the dependences on structural variables and show good agreements with the experimental results. We demonstrate the application of interfacial enhanced yarns as wearable logic HMIs to remotely control the robotic hand and manipulate the color switching of light on the basis of gesture recognition. We hope that the SSSYs strategy can shed an extra light in future HMIs development and incoming IoT and artificial intelligence (AI) technologies.
