Year: 2025

Abstract: The combination of flexible sensors and bionic innovative design has become an important direction for the development of intelligent sensing technology. To this end, this paper systematically describes the latest research progress of bionic sensors inspired by the synergistic mechanism of “stress concentration-high pass filtering-omnidirectional localization” of scorpion slit receptors. First, it presents breakthroughs such as ultra-high sensitivity through gradient-cracked structures, dynamic signal decoupling mediated by viscoelastic materials, and omnidirectional localization accuracy supported by curvilinear array layouts. Aiming at the cross-interference and integration redundancy problems faced by traditional multimodal sensing systems, this paper introduces a vertically stacked heterogeneous integration strategy. Through the synergistic design of bionic stretchable conductive film and strain-isolated communication interfaces, a flexible multimodal sensing system with pressure-temperature bimodal sensing, multiaxial stress decoupling, and spatial distribution tracking capability is successfully constructed. Relevant research further confirms that the bionic architecture shows significant advantages in medical monitoring, industrial equipment health management and lunar rover terrain sensing scenarios. It provides a new paradigm of cross-scale structure-function synergistic optimization for the development of adaptive intelligent sensing systems in extreme environments, and marks an important leap in the integration of bionic flexible electronics from single-device innovation to systematic technology.
