Power transmission lines require constant monitoring even in remote regions. Recently, a team of researchers from Hanyang University has proposed a novel unmanned aerial vehicle-based approach that utilizes multi-modal sensors for environmental infringement and sag estimation for power transmission lines. The presented technique is expected to revolutionize automated infrastructure monitoring, paving the way for cost-efficient, resilient, and more robust technologies.

Ensuring food quality and safety is of supreme importance. In this direction, researchers from Hanbat National University, Korea University (Sejong campus), and Korea Institute of Machinery and Materials have developed an innovative surface-enhanced Raman scattering sensor integrated in stretchable and antimicrobial wrapper for real-time food quality monitoring and preservation. The real-world uses of this technology span the entire farm-to-fork chain, including cold-chain logistics and storage, retail smart packaging, food-safety screening, and meal-kit delivery.

An image-only artificial intelligence (AI) model for predicting the five-year risk of breast cancer provided stronger and more precise risk stratification than breast density assessment, according to a new study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Developing effective, versatile, and high-precision sensing interfaces remains a crucial challenge in human–machine–environment interaction applications. Despite progress in interaction-oriented sensing skins, limitations remain in unit-level reconfiguration, multiaxial force and motion sensing, and robust operation across dynamically changing or irregular surfaces. Herein, we develop a reconfigurable omnidirectional triboelectric whisker sensor array (RO-TWSA) comprising multiple sensing units that integrate a triboelectric whisker structure (TWS) with an untethered hydro-sealing vacuum sucker (UHSVS), enabling reversibly portable deployment and omnidirectional perception across diverse surfaces. Using a simple dual-triangular electrode layout paired with MXene/silicone nanocomposite dielectric layer, the sensor unit achieves precise omnidirectional force and motion sensing with a detection threshold as low as 0.024 N and an angular resolution of 5°, while the UHSVS provides reliable and reversible multi-surface anchoring for the sensor units by involving a newly designed hydrogel combining high mechanical robustness and superior water absorption. Extensive experiments demonstrate the effectiveness of RO-TWSA across various interactive scenarios, including teleoperation, tactile diagnostics, and robotic autonomous exploration. Overall, RO-TWSA presents a versatile and high-resolution tactile interface, offering new avenues for intelligent perception and interaction in complex real-world environments.
