Ga-Based Liquid Metals: Advances in Interface Thermal and Electrical Regulations for Power Electronics Integration
Ga-based liquid metals (GLMs) have been considered as promising thermal and electrical interface materials for advanced power electronics, combining high thermal conductivity (some types even >30 W/m·K) with fluidity at room temperature. This review systematically evaluates the dual roles of GLMs in power electronics packaging. Their function in thermal management as both thermal interface materials […]
Biaxially Oriented High-Thermal-Conductivity Electromagnetic Wave Absorber Based on Interlayer Phonon Bridge Construction
Electronic packaging materials that exhibit favorable electromagnetic wave absorption (EMA) and thermal conductive features are critically important for the protection of growing high-power advanced electronics. However, existing bifunctional materials emphasize only single EMA performance and suffer from severely insufficient thermal conductivity. Thus, it remains an enormous challenge to develop a highly thermally conductive electromagnetic absorber. […]
Mojo Vision : du pari de la lentille au trône du Micro-LED

Three Verticals for Drone-Based Lidar Beyond Surveying and Mapping
When we think about the use of lidar technology within the commercial drone sector, surveying and mapping comes immediately to mind. There’s good reason for this, as the surveying community overall was among the earliest adopters of lidar, and while applications in autonomous driving have driven the technology forward, surveyors remain near the top of […]
Tri-Modal Fusion Transformers for UAV-based Object Detection
Reliable UAV object detection requires robustness to illumination changes, motion blur, and scene dynamics that suppress RGB cues. Thermal long-wave infrared (LWIR) sensing preserves contrast in low light, and event cameras retain microsecond-level temporal edges, but integrating all three modalities in a unified detector has not been systematically studied. We present a tri-modal framework that […]
