Abstract Human‐machine interfaces (HMIs) serve as essential channels for communication between humans and machines. However, current HMIs often require the integration of batteries, multiple sensing components, electrodes, resulting in complex configurations, limited flexibility, poor scalability. In this work, a body‐coupled mechanism employing power–frequency electric magnetic field an energy source is proposed, HMI with double spiral electrode structure (DS‐HMI) has been designed based on mechanism. By comparing output peaks two electrodes encoding binary codes “0” “1”, DS‐HMI detects directions without need batteries or algorithms. The device demonstrates ultralow detection threshold (< 0.02 N), exceptional durability (> 100 000 cycles), robustness, high scalability, rapid capabilities (single‐bit completed 8 ms). successfully implemented security code systems, UAV control interfaces, robotic leg interfaces. This work offers novel insights principles advancing next‐generation interactive electronic devices, broad applications IoT, smart homes, VR/AR technologies.

The heel pad, located under the calcaneus of human foot, is a hidden treasure that has been subjected to harsh mechanical conditions such as impact, vibration, and cyclic loading. This resulted in unique compartment structure material composition, endowed with advanced biomechanical functions including cushioning, vibration reduction, fatigue resistance, touchdown stability, making it an ideal natural bionic prototype field materials. It shown highly specialized composition pad endows properties hyperelasticity, viscoelasticity, anisotropy. These complex underpin its functions. Although known these interact each other, detailed influence mechanism remains unclear, which restricts application Therefore, this study provides comprehensive review structure, materials, properties, pad. focuses on elucidating relationships between pads proposes insights for materials using prototype. Finally, research idea analyze by integrating sophisticated technologies proposed, aiming provide directions further in-depth inspiration innovative design
