Summary: In this paper, a wireless passive temperature sensor based on a metamaterial structure is proposed to measure the temperature of moving parts. The sensor consists of an alumina ceramic substrate with a square metal double split-ring resonator. By detecting the change in the resonant frequency of the sensor using a wireless antenna, the temperature sensing operation is realized. The sensor has a high temperature sensitivity of 205.22 kHz/°C and a strong linear response, making it suitable for temperature measurement of rotating parts.

Summary: This paper studies the distributed routing protocol for frequency-switchable MI-WUSNs, which are wireless underground sensor networks based on magnetic induction. To address the frequency-selective property and ensure network connectivity in the underground environment, a frequency-switch strategy is introduced. The paper maps the frequency-switchable MI-WUSN to a multi-layer network and describes its routing decision in the Q-Learning framework. The proposed routing protocol is validated through simulation experiments.

Summary: Waterseepage-induced geological hazards (SIGHs), such as landslides, collapse, debris flow, and ground fissures, often lead to significant human casualties, economic losses, and environmental damage. However, effectively predicting and warning about the occurrence of water seepage remains a challenge. In this study, a self-powered, cost-effective, reliable, and sensitive SIGH early warning system (SIGH-EWS) is presented, which utilizes all-solid, sustainable, fire retardant, and safe-to-use bio-ionotronic batteries to power the Internet of Things chipsets. These batteries exhibit exceptional sensitivity to humidity and water, enabling the detection of water seepage. By integrating energy management and wireless communication systems, the SIGH-EWS can provide timely alerts for early water seepage in different water and soil environments with a resolution of seconds. The SIGH-EWS demonstrates great potential for the early warning of geological disasters and offers valuable design strategies for next-generation hazard alarm systems.

Summary: Quantum secure metrology protocols utilize quantum effects to achieve enhanced precision and security in probing remote systems. This paper proposes a QSM scheme that employs Bell pairs for unconditional security and offers precision scaling beyond the standard quantum limit. The comparative analysis demonstrates the superiority of the controlled encoding strategy over the parallel encoding of multi-partite entangled states in terms of parameter secrecy. Additionally, a trade-off relationship between maximum achievable precision and security under limited resource availability is identified and characterized. The dynamic scalability of the proposed protocol makes it suitable for large-scale network sensing scenarios.

Summary: This study focuses on improving the electrical output and tribological performance of triboelectric nanogenerators (TENGs) by adding a mixture of hexadecane and onion-like carbon (OLC) lubricant to the interface between polytetrafluoroethylene (PTFE) film and steel. The addition of hexadecane reduces friction and wear, while the introduction of OLC further enhances the electrical output and tribological properties of the TENG. The oil-OLC-based lubricant reduces transfer film formation, increases effective contact area, and forms a micro-bearing, thus improving the TENG's efficiency and service life.

Summary: In this study, polyethylene glycol-phytic acid (PEG-PA) composite liquid lubricants were obtained, which showed outstanding superlubricating properties for Si3N4/glass friction pairs with an ultrashort running-in period under high Hertzian contact pressure. Even after 12 hours of use, only about 100 nm deep wear scars were found on the glass surface. The low shear force between water molecules and the strong hydrogen bond interaction between PEG and PA greatly contribute to the lubricant's performance.
