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 sensors are a significant component of flexible electronics for medical activity and human physiology monitoring. However, obtaining multifunctional sensor by simple process is still challenge. Herein, we propose transfer laser-induced graphene (LIG) onto polydimethylsiloxane. The uniform microcracks formed in the LIG layer during process, which enabled sensitive, stable sensing with multiplex functions including stretching, bending, twisting, pressing. properties were investigated. It proved that constructed delivered good performances. BoxLucas1 model, first time, proposed to simulate mechanism perfectly. porous microstructures high-performance sensor. various physical vibration signals motions monitored sensor, proving potential applications fields health movement A touch panel portable signal display system was constructed, sensor's application screen electronics. self-healable also demonstrated.

Abstract A fibrous flexible sensor, with its small size, minimally burdens the human body, ranking among most user‐friendly sensors. However, application is often limited by damage caused electrode movement, as sensors are typically attached to joints, which can be greatly alleviated placing two electrodes on same side. Inspired hydrogen bonds in double‐helical structure of DNA, design commonly found and applied fiber‐based batteries supercapacitors into through coaxial wet‐spinning further treatment. The double helical sensor exhibits high strength maintains stable operation prepared under over 300% strain gauge factors (GF) 0.9, 39.5, 349, respectively, working ranges. This unique single‐sided also enabled applications such water flow sensing. a smart glove capable real‐time integrated, five‐channel finger motion detection, used convolutional neural network (CNN)‐based machine learning algorithm achieve 98.8% accuracy recognizing six common gestures. study provides novel approach optimize distribution an internally encapsulated structure, making significant contribution field

The preparation of foams with self-healing properties and stable cell structures continues to present significant challenges. In this study, a polydimethylsiloxane elastomer featuring dual network structure was developed. A dynamic cross-linking network, formed by hydrogen disulfide bonds, imparted capabilities the elastomer. inclusion agent created an inherent that improved mechanical melt strength synthesized demonstrated exceptional performance, achieving efficiency 92.89%, along impressive properties, including tensile 6.32 MPa elongation at break 1277.80%. Additionally, foam fabricated using supercritical carbon dioxide (sc-CO2) foaming method. With increase in cross-linking, size decreased from 11.88 8.60 μm, while density increased 2.04 × 109 2.71 cells/cm3, resulting uniform distribution within foam. Microcracks were effectively healed 10 min 80 °C, morphology remained after 96 h exposure environmental conditions. This dual-network exhibited excellent performance structure.
