Abstract Ionic conductive hydrogels have emerged as an excellent option for constructing dielectric layers of interfacial iontronic sensors. Among these, gradient ionic hydrogels, due to the intrinsic elastic modulus, can achieve a wide range pressure responses. However, fabrication with optimal mechanical and sensing properties remains challenge. In this study, it is discovered first that phytic acid (PA) interacts in remarkably distinct manners (i.e., plasticizing effects phase separation) different polymers polyacrylamide polyacrylic acid). This distinctive PA‐polymer interacting mechanism innovatively utilized construct modulus hydrogel through simple precursor solution infiltration approach. The hydrogel‐based flexible sensor not only achieves high sensitivity (9.00 kPa −1 , <15 kPa) broad (from ≈3.7 Pa 1.2 MPa) simultaneously, but also exhibits superior low performance. It successfully recognizes subtle acoustic waves airflow, well moderate speaking finger pressing magnitude plantar pressure. addition, demonstrates remarkable antibacterial biocompatibility. functional performance bioactivity exceptional potential wearable applications.

Abstract Traditional hydrogels tend to freeze and lose performance at low temperatures, limiting their applications. Additionally, need exhibit hysteresis, excellent cycling stability, self‐adhesion ensure high‐quality signal acquisition in complex environments. To address this challenge, study designed a dual‐network gel glycerol (Gly)/H 2 O solvent system. Due the combination of chemical physical crosslinking (hydrogen bonding electrostatic interactions), resulting exhibits skin‐adaptive modulus, high anti‐freezing ability, body temperature‐induced adhesion, electrical performance, making it suitable for wearable sensors temperatures. Based on gel, single‐electrode triboelectric nanogenerator (gel‐TENG) is developed, achieving efficient conversion mechanical energy into energy. Further applied smart insole, successfully enabled real‐time visualization plantar pressure distribution skiing motion recognition. Using random forest machine learning algorithm, system accurately classified 11 basic motions, classification accuracy 97.1%. This advances flexible self‐powered systems, supporting intelligent materials research extreme

Abstract Mechanical information is a medium for perceptual interaction and health monitoring of organisms or intelligent mechanical equipment, including force, vibration, sound, flow. Researchers are increasingly deploying recognition technologies (MIRT) that integrate acquisition, pre‐processing, processing functions expected to enable advanced applications. However, this also poses significant challenges acquisition performance efficiency. The novel exciting mechanosensory systems in nature have inspired us develop superior bionic (MIBRT) based on materials, structures, devices address these challenges. Herein, first strategies pre‐processing presented their importance high‐performance highlighted. Subsequently, design considerations sensors by mechanoreceptors described. Then, the concepts neuromorphic summarized order replicate biological nervous system. Additionally, ability MIBRT investigated recognize basic information. Furthermore, further potential applications robots, healthcare, virtual reality explored with view solve range complex tasks. Finally, future opportunities identified from multiple perspectives.

Flexible magnetic tactile sensors hold transformative potential in robotics and human-computer interactions by enabling precise force detection. However, existing face challenges balancing sensitivity, detection range, structural adaptability for sensing force. This study proposed a pre-compressed magnetization method to address these limitations amplifying the magnetoelastic effect through optimized direction distribution of elastomer. A body-centered cubic lattice-structured magnetoelastomer featuring regular deformation under compression was fabricated via digital light processing (DLP) validate this method. Finite element simulations experimental analyses revealed that magnetizing material 60% strain distribution, enhancing force-magnetic coupling. Integrating elastomer with hall sensor, prepared sensor demonstrated low limit (1 mN), wide range (0.001-10 N), rapid response/recovery times (40 ms/50 ms), durability (>1500 cycles). By using machine learning, enabled accurate 3D prediction.
