However, existing technologies struggle with a fundamental limitation, as the pinning force of the contact line significantly resists liquid motion. In this study, a novel strategy is introduced to govern fluid motion and overcome this barrier. Our approach involves positioning a nanofluid slug within a sealed capillary tube and directing irradiation to one side of the slug. Intensive local vaporization of nanofluid is generated due to the thermo-plasmonic effect of nanoparticles, leading to a considerable driving force and rapid motion of the slug. Based on this principle, the opto-thermoplasmonic pneumatic piston was proposed. The direction of motion is controlled by modulating the laser irradiation direction. Furthermore, the laser beam parameters enable adjustable piston oscillation frequency and speed. To better understand the characteristics of the opto-thermoplasmonic pneumatic piston, theoretical studies were conducted to analyze the kinetic characteristics of the piston, revealing an expression consistent with the Kelvin-Voigt model. Various factors affecting the performance of the pneumatic pistons were also studied.

Herein, we present the experimental findings regarding the composites based on chitosan matrix with few-layered graphene (FLG), which is uniformly distributed in the matrix through the use of amphiphilic stabilizers Pluronic F108 and polyvinylpyrrolidone. The variation of the stabilizers and FLG content enables the modification of composite morphology and subsequent alteration of piezoresistive effect. The resistivity of the composites ranges from 1.6 up to 130 000 Ohm·cm, corresponding to a change in the strain gauge factor from 1.3 to 5.7. To elucidate the morphology and physical nature of the piezoresistive effect, the mechanisms of electrical conductivity were analyzed from room temperature down to cryogenic ones. At sufficiently high FLG content, FLG nanoparticles are observed to be in contact with each other in the current pathways; in the composites with lower FLG content, there are polymer gaps between the FLG particles. At low temperatures, the electrical conduction mechanism is variable-range hopping, which is caused by the defectiveness and small dimensions of the FLG particles. The composites have been demonstrated to exhibit functionality at a strain value of up to 40 %, with a Young’s modulus of 270 MPa and a tensile strength of 68 MPa.

This research introduces an innovative, wearable, ultra-wideband (UWB) flexible antenna combined with a metamaterial structure (MM) for Wireless Body Area Sensor Networks (WBASNs). The suggested design features a 7 × 7 array of artificial magnetic conductor (AMC) unit cells located at the rear of the antenna, serving as a reflector. This design markedly diminishes back radiation, decreases the Specific Absorption Rate (SAR), augments gain, and enhances the Front-to-Back Ratio (FBR). The antenna is composed entirely of textile materials, exhibiting flexibility, durability, cost-effectiveness, lightweight properties, and ease of fabrication. Its conformal shape guarantees comfort and versatility, which is ideal for WBASN applications. The antenna with the AMC attains a functional bandwidth (S₁₁ &lt; −10 dB) of 7.9 GHz (5.1 GHz to 13 GHz), encompassing the UWB frequency spectrum. Without the AMC, the simulated SAR values for 10 g of human tissue are 0.751, 1.06, and 0.715 W/kg at frequencies of 6, 8, and 11 GHz, respectively. Utilizing the AMC with the antenna, these values significantly diminish to 0.0784, 0.0252, and 0.0532 W/kg, indicating an average SAR reduction of 96.84 % over the evaluated frequencies. This reduction guarantees compliance with international safety standards. The incorporation of the AMC array results in a significant enhancement in broadband gain, increasing the peak gain from 2.55 dBi to 9.14 dBi, thus reaching an improvement of 6.59 dBi. Deformation analysis verifies uniform performance in both curved and planar shapes. The fabrication procedure is uncomplicated, and experimental outcomes closely align with simulations, indicating reliability in both free-space and on-body settings.
