Sensilla Trichoidea-Inspired, High-Temperature, and Omnidirectional Vibration Perception Based on Monolayer Graphene
This groundbreaking research introduces a novel 3D cilia-like monolayer graphene omnidirectional vibration transducer (CGVT) inspired by spider sensilla trichoidea. Fabricated through a stress-induced self-assembly technique, these bioinspired MEMS devices achieve exceptional performance, including high charge sensitivity (87.95 pC g⁻¹), a wide vibration monitoring range (1 Hz-10 kHz, 0-1120 g), and remarkable high-temperature resistance up to 800 °C with a thin Si3N4 coating. The system also features an omnidirectional decoupling algorithm based on a 1D convolutional neural network for precise vibration direction discrimination, achieving 97.18% accuracy. Monolithically integrated using silicon-based semiconductor processing, this technology significantly miniaturizes components and holds immense potential for intelligent vibration monitoring in harsh environments.

Graphene Flexoelectricity
Monolayer graphene, inherently centrosymmetric, gains flexoelectric properties when self-assembled into 3D semicircular structures. This stress-induced deformation breaks symmetry, generating polarization charges under vibration, enabling self-powered electromechanical transduction without external bias.

Enhanced Durability in Industrial Applications
A major manufacturing client needed vibration monitoring for machinery operating in high-temperature industrial furnaces, where standard sensors failed above 250 °C. Deploying the CGVT with its 20-nm Si₃N₄ coating, we achieved continuous, accurate monitoring at 650 °C for over six months, leading to a 25% reduction in unexpected downtime and significant maintenance cost savings. The high-temperature resilience of CGVT enabled predictive maintenance in previously impossible conditions.
