Abstract Material composition and structural design are important factors influencing the electromagnetic wave (EMW) absorption performance of materials. To alleviate impedance mismatch attributed to high dielectric constant Ti 3 C 2 T x MXene, we have successfully synthesized core‐shell structured SiO @MXene@MoS nanospheres. This architecture, comprising as core, MXene intermediate layer, MoS outer shell, is achieved through an electrostatic self‐assembly method combined with a hydrothermal process. complex structure not only provides variety loss mechanisms that effectively dissipate energy but also prevents self‐aggregation nanosheets. Notably, synergistic combination highly conductive enables suitable composites, ensuring optimal matching. Therefore, nanospheres exhibit excellent EMW performance, featuring remarkable minimum reflection (RL min ) −52.11 dB (2.4 mm). It noteworthy these achieve ultra‐wide effective bandwidth (EAB) 6.72 GHz. work novel approach for designing synthesizing high‐performance absorbers characterized by “wide strong loss.”

Graphene remains of great interest in biomedical applications because biocompatibility. Diseases relating to human senses interfere with life satisfaction and happiness. Therefore, the restoration by artificial organs or sensory devices may bring a bright future recovery patients. In this review, we update most recent progress graphene based sensors for mimicking such as retina image sensors, eardrums, gas chemical tactile sensors. The brain-like processors are discussed on conventional transistors well memristor related neuromorphic computing. brain–machine interface is introduced providing single pathway. Besides, muscles summarized means actuators order react physical world. Future opportunities remain elevating performances human-like their clinical applications.
