Abstract High-performance flexible pressure sensors have garnered significant attention in fields such as wearable electronics and human-machine interfaces. However, the development of that simultaneously achieve high sensitivity, a wide detection range, good mechanical stability remains challenge. In this paper, we propose piezoresistive sensor based on Ti 3 C₂Tx (MXene)/polyethylene oxide (PEO) composite nanofiber membrane (CNM). The sensor, utilizing MXene (0.4 wt%)/PEO (5 wt%), exhibits sensitivity (44.34 kPa −1 at 0−50 kPa, 12.99 50−500 kPa) can reliably monitor physiological signals other subtle cues. Moreover, features range (0−500 kPa), fast response recovery time (~150/45 ms), excellent (over 10 000 cycles maximum load). Through an MXene/PEO array, demonstrate its applications human signal monitoring, providing reliable way to expand application MXene-based sensors.

Graphene-based terahertz (THz) metamaterials (MMs) are at the forefront of high-sensitivity sensing, with applications spanning biochemical to environmental fields. This review examines recent advances in graphene MMs-based THz sensors, covering foundational theories and innovative designs, from complex patterns graphene-dielectric graphene-metal hybrids. We explore ultra-trace detection enabled by $$\pi$$ - stacking mechanisms, expanding capabilities beyond conventional refractive index-based methods. Despite significant theoretical progress, practical challenges remain due material constraints; solutions such as multilayer structures hybrid low-mobility designs discussed enhance experimental feasibility. provides a comprehensive perspective on evolving impact MMs, positioning them transformative tools multidisciplinary sensing.
