The latter is particularly beneficial for sensing applications, as it ensures the device remains unaffected by pressure variations, eliminating the need for an additional packaging system. By exploiting mode coupling between the frequencies of symmetric and anti-symmetric modes, the sensors exhibited significant frequency and amplitude shifts across a pressure range of 0.1–760 Torr.

The third device showed a robustness against pressure variations, with one mode selectively insensitive to pressure but responsive to other stimuli, enabling multimodal sensing capabilities. Moreover, the device has been tested under temperature environmental variation, showing a low sensitivity of 20.4 ppm/⁰C.

While robotic automation has advanced across manufacturing, aerospace machining remains difficult to automate due to strict quality requirements and the lack of intelligent, real-time fault monitoring. During machining, skilled human operators rely on their tactile perception to detect subtle faults such as tool wear, misalignment, or insufficient feed force through vibration cues. Replicating this level of high-resolution tactile fidelity in robotic systems remains a key challenge. We present an event Vision-Based Tactile Sensor (EVBTS) that enables robots to perceive and interpret machining vibrations with a human-like sense of touch. The sensor uses an event camera to observe a deformable, marker-embedded membrane, capturing fine-grained spatiotemporal deformation patterns with microsecond latency. This high-fidelity, biomimetic signal stream allows robotic systems to detect faults in machining dynamics. We evaluate EVBTS on a robotic drilling setup for aerospace nutplate installation, spanning 12 distinct machining conditions.

Sapphire fibre possesses outstanding high-temperature stability and serves as a promising waveguide for ultra-high-temperature fibre sensors.

To mitigate this limitation, this paper proposes a few-mode sapphire fibre with femtosecond-laser-fabricated modulated cladding, whose structural parameters are optimised via finite-element simulation. We investigate how refractive-index variation, modulation-unit geometry and unit spacing govern fundamental-mode transmission and mode confinement. Simulation results demonstrate that the negative-index modulation array inside a 125 μm sapphire fibre delivers effective high-order-mode suppression at Δn = −0.008 and unit spacing d = 5.0 μm. Under optimised conditions at the 1.55 μm communication band, the fundamental-mode energy fraction exceeds 0.95, suppressing multimode-interference noise.

Successive current–voltage sweeps with varying cutoff voltages demonstrate multilevel, finely tunable resistance states over a broad range without any compliance current. Charge–flux analysis confirms that the device operates as a true memristor, and cumulative conductance buildup under sequential positive and negative biases indicates robust, polarity-independent switching. Moreover, tuning the voltage sweep rate modulates the inertia of charge carriers that governs the switching kinetics. The GO–CoO architecture establishes a conductive network wherein oxygen vacancy dynamics within CoO particles and conductive rGO formation collectively govern analog resistive switching, providing the essential tunability and stability required to emulate synaptic plasticity. Under optimized pulsed stimulation, the memristor faithfully emulates key nociceptive neural responses, including a threshold response, peripheral sensitization (manifested as hyperalgesia and allodynia), central sensitization (temporal summation and facilitation), suprathreshold response, and post-stimulus recovery.

Chemiresistive semiconducting metal oxide sensors are attractive for their simple architecture and high sensitivity, but their performance often drops at room temperature and they still face selectivity challenges, which limit their practical deployment. Here, we address the challenge of room-temperature operation in chemiresistive semiconducting metal oxides-based sensors by engineering magnesium (Mg)-doped porous ZnFe₂O₄ microspheres (ZFM) and integrating them with platinum-decorated carbon nanotubes (CP). This composite design is expected to enhance room-temperature H₂ sensing by increasing defect-mediated adsorption on the ZFM surface, facilitating efficient charge transport through the CNT network and accelerating reaction kinetics <em>via</em> Pt-assisted H₂ dissociation. A two-step optimization strategy was adopted to establish composition–microstructure–property correlations: CP loading (0.1, 0.25, 0.5, 0.75 and 1 wt%) was first varied at an intermediate Mg (10 wt%) to investigate the effect of CNT/Pt network evolution, and then the optimal CP level (0.5 wt%) was kept constant while the Mg content (5–15 wt%) was varied. All the prepared composites were comprehensively characterized using XRD, FESEM, EDX, TEM, FTIR, UV–Vis, BET, and XPS to identify their phase composition, morphology, porosity, and surface chemical states. The sensing layers were fabricated by drop-casting onto epoxy-glass electrodes and tested under ambient conditions toward different H₂ concentrations. The optimized ZFM10-CP0.5 sensing layer showed the best performance with a response of 2.2 at 10000 ppm H₂ with fast response/recovery (11/90.9 s) and preferential response toward H₂ relative to the tested organic interferents methanol, ethanol, ethylene glycol, and DMF, while maintaining approximately 90% of its H₂ response at 70% relative humidity. XPS, BET, and FESEM collectively suggest that Mg doping increases the contribution of defect-related surface oxygen species, while 0.5 wt% CP provides a more continuous conductive network and accessible porous interface, consistent with the improved H₂ response of ZFM10–CP0.5.
