In the post-pandemic era, human demand for a healthy lifestyle and smart society has surged, leading to vibrant growth in field of flexible electronic sensor technology health monitoring. Flexible polymer humidity sensors are not only capable real-time monitoring respiration skin moisture information but also serve as non-contact human–machine interaction method. addition, development moist-electric generation is expected break free from traditional reliance devices on power equipment, which significant importance miniaturization, reliability, environmentally friendly devices. Currently, playing role wearable thus have attracted considerable attention. This review begins by introducing structural types working principles various sensors, including capacitive, impedance/resistive, frequency-based, fiber optic, voltage-based sensors. It mainly focuses latest research advancements particularly modification humidity-sensitive materials, fabrication, hygrosensitivity mechanisms. Studies material composites different polymers, polymers combined with porous nanostructured metal oxides, two-dimensional materials reviewed, along comparative summary fabrication performance mechanisms related paper concludes discussion current challenges opportunities faced providing new perspectives their future development.

Chronic respiratory diseases (CRDs) are the leading causes of death worldwide. Monitoring both inhalation and exhalation is crucial for lung function assessment patient outcomes. However, current sensors lack sufficient stability also ability to differentiate between exhalation, limiting clinical effectiveness. Inspired by bat-wing hair structures, we report an all-optical fiber sensilla bidirectional airflow detection. Optical Merkel cells microhairs integrated at tip through femtosecond laser 3D nanoprinting. Bidirectional interacts with inducing opposing nanoscale deformations cells, which spectral drift in different directions. The device enables flow detection sensitivities 19.16 nm/(L/min) −24.46 nm/(L/min), a record-high over 10,000 cycles. ultracompact design allows seamless integration into trachea or masks. effectively identifies patterns, distress signals, apnea signs, providing noninvasive precise tool CRD management emergency response.

This paper reports several preliminary investigations concerning the relative humidity (RH) detection response of a chemiresistive sensor that uses novel sensing layer based on pristine carbon nano-onions (CNOs) and polyvinyl alcohol (PVA) at 1/1 2/1 w/w ratio. The device, including Si/SiO2 substrate gold electrodes, is obtained by depositing CNOs-PVA aqueous suspension structure drop casting. composition morphology film are explored means scanning electron microscopy, Raman spectroscopy, atomic force X-ray diffraction. manufactured sensor's room temperature RH performance examined applying continuous flow electric current between interdigitated electrodes measuring voltage as varies from 5% to 95%. For below 82% (sensing ratio) or 50.5% ratio), resistance linearly with RH, moderate slope. newly developed sensor, using 1:1 ratio (w/w), responded well better than reference sensor. At same time, recorded recovery time was about 30 s, which half Additionally, changes in (ΔR/ΔRH) for different levels showed more sensitive above 80%. main mechanisms considered discussed decrease hole concentration CNOs during interaction an donor molecule, such water, swelling hydrophilic PVA. experimental data analyzed compared results reported previously published work detectors employing layers oxidized nanohorns-polyvinylpirrolidone (PVP), nanohorns-PVA CNOs-polyvinylpyrrolidone.
