Active sensing is a fundamental aspect of human and animal interactions with the environment, providing essential information about the hardness, texture, and tackiness of objects. This ability stems from the presence of diverse mechanoreceptors in our skin, capable of detecting a wide range of stimuli and from the sensorimotor control of biological mechanism. In contrast, existing tactile sensors for robotic applications typically excel in identifying only limited types of information, lacking the versatility of biological mechanoreceptors and the requisite sensing strategies to extract tactile information proactively. Here, inspired by human haptic perception, we develop a skin‐inspired artificial 3D mechanoreceptor (SENS) capable of detecting multiple mechanical stimuli to bridge sensing and action in a closed‐loop sensorimotor system for dynamic haptic exploration. A tensor‐based non‐linear theoretical model is established to characterize the 3D deformation (e.g., tensile, compressive and shear deformation) of SENS, providing guidance for the design and optimization of multimode sensing properties with high fidelity. Based on SENS, we further demonstrate a closed‐loop robotic system capable of recognizing objects with improved accuracy (∼96%). This dynamic haptic exploration approach shows promise for a wide range of applications such as autonomous learning, healthcare, and space and deep‐sea exploration.This article is protected by copyright.

“…The detection and quantitation of mercury in traditional Chinese medicine preparation were achieved by using silver NPs (AgNPs) as the Raman substrate and Dpy as the signal probe (Figure 5C). 81 In this methodology, Dpy was adsorbed onto the surface of AgNPs through an Ag-N bond. subsequently, sodium chloride was introduced as a supplement to induce the aggregation of AgNPs, thereby enhancing its signal.…”

“…[ 10,11 ] Zhang et al [ 12 ] further improved the curved arm structure by incorporating specific mass blocks, resulting in a material with a negative Poisson's ratio and viable photonic band structures. Zhang et al introduced a design for a periodic lattice structure network material, [ 13,14 ] utilizing spiral microstructures arranged in a periodic manner as building blocks for lattice nodes. This structure is directly created through additive manufacturing methods, accurately replicating the anisotropic and nonlinear stress–strain behavior observed in biological tissues.…”

This work aims to significantly improve the mechanical properties of conventional rigid lattice structures under repeatable large deformations. A novel hybrid material is proposed based on the concept of interpenetrating composite materials. The material utilizes a woven TC4 orthogonal spiral wire mesh as the skeleton and PU elastomer (OSWM‐PU) as the matrix. The uniaxial tensile tests demonstrate that OSWM‐PU possesses the excellent load‐bearing capacity, allowing for large deformations (≥ 60%) while maintaining partial integrity even after matrix fracture. Optical measurements and simulation analysis reveal that Poisson’s ratio can be adjusted within a certain range by manipulating the microscopic parameters (p, d) of the longitudinal helical filaments. Cyclic tensile experiments further demonstrate that OSWM‐PU exhibits exceptional energy absorption performance, multiple energy dissipation modes, and a more pronounced Mullins effect. The stress relaxation experiment reveals the significant influence of the volume fraction of the skeleton on long‐term loading conditions. The orthogonal spiral wire skeleton exhibits a superior hooking effect without dividing the matrix, enabling OSWM‐PU to possess enhanced collaborative deformation capability and inherent designability in the orthogonal direction. These characteristics make it highly promising for applications in various robot joints and as flexible aircraft skin, offering excellent prospects for utilization.This article is protected by copyright.
