The demand for self-powered, flexible, and wearable electronic devices has been increasing in recent years physiological biomedical applications real-time detection due to their higher flexibility stretchability. This work fabricated a highly sensitive, self-powered microdevice with Poly-Vinylidene Fluoride-Tetra Fluoroethylene (PVDF-TrFE) nano-fibers using an electrospinning technique. dielectric response of the polymer was improved by incorporating reduced-graphene-oxide (rGO) multi-walled carbon nano-tubes (MWCNTs) through doping. behavior piezoelectric effect were stretching orientation polymeric chains. outermost layer attained chemical vapor deposition (CVD) conductive poly (3,4-ethylenedioxythiophene) enhance electrical conductivity sensitivity. hetero-structured nano-composite comprises PVDF-TrFE doped rGO-MWCNTs over (PEDOT), forming continuous self-assembly. pressure sensor is capable detecting human vital signs. exhibits high-pressure sensitivity 19.09 kPa−1, sensing range 1.0 Pa 25 kPa, excellent cycling stability 10,000 cycles. study reveals that superior performance monitoring signs, including heartbeat wrist pulse, masticatory movement, voice recognition, eye blinking signals. research demonstrates device could potentially eliminate metallic sensors be used early disease diagnosis personal healthcare applications.

Electromagnetically induced transparency (EIT) originating from quantum physics can lead to a very narrow-band transparent window, which is sensitive minor environmental changes. The rational construction of highly EIT metamaterials facilitates its wide sensing application in the terahertz (THz) range. In this work, we designed what believe be novel polarization-independent metamaterial sensor composed four symmetrical Chinese Taichi-like rings and crossed-shaped structure. excite high-quality planar toroidal dipole resonator simultaneously structure induces electric resonance. effect realized by two strongly coupled resonators. shows higher characteristics for ultrathin analyte refractive index than that resonance models alone. sensitivity reaches maximum value 331.3 GHz/RIU at saturated thickness 10 µm. sensitivities are most reported sensors same frequency (range 0.49 THz 2.77 THz) with 2 µm 15 µm). We experimentally fabricated demonstrated fascinating effect. Our results pave way design ideas new polarization-insensitive high-performance tuned band.

Flexible wearable sensors have increasingly contributed to human health detection and physiological signal acquisition in recent years. Nevertheless, developing high‐performance that can achieve high sensitivity wide range align with environmentally friendly principles remains a significant challenge. Herein, novel flexible paper‐based pressure sensing platform, which the conductive layer is made of paper dome structure on top, demonstrated. The functions similarly microstructures created via complex processes, both enhancing sensor sensitivity. material selected carbon ink nanotubes, offering benefits cost‐effectiveness conductivity. In results, it shown has (6.78 kPa −1 , <10 kPa), linearity 0.99 under 10 kPa, low lower limit detection, dynamic response (157 ms) demonstrates good repeatability over 1000 cycles. Due its performance, effectively detects subtle large motions. This exceptional performance attributed rough fibers paper's surface protruding structure, enhance sensor's ability sense signals. proposed this study offer an economical solution potential detection.
