In recent years, conductive hydrogels have become popular substrates for flexible sensors because of their good mechanical properties, electrical conductivity, and biocompatibility.In this paper, the authors solved key problem complex preparation technology prepared polyvinyl alcohol/silver nanoparticles (PVA/AgNPs) sensor with high tensile, sensitivity, stability systems.They were by a simple efficient method doping AgNPs into three-dimensional network PVA hydrogels.The had large draw ratio...
Organic piezoelectric materials are emerging as integral components in the development of advanced implantable self-powered sensors for next generation.
With the development of technology and improvement living standards, hydrogel-based strain sensors have attracted more attention.However, fabrication hydrogel with desirable mechanical piezoresistive properties is still challenging.Herein, a double-layer flexible sensor presented, which made carbon nanotubes (CNTs) polyvinyl alcohol (PVA) high stretchability up to 415% super compressibility 92% strain, considerable electrical conductivity (1.11 S m -1 ).The show great linearity throughout...
Abstract Mechanical antennas based on piezoelectric materials can effectively reduce the size of long wave down to 1/1000 wavelength (from km scale mm level). However, narrow bandwidth and weak field intensity seriously restrict its practical applications in transmission distance channel capacity. Here, a mechanical antenna‐based electrostrictive effect relaxor ferroelectric ceramic (PMN‐PT) is proposed improve radiation capacity achieve ultra‐wideband characteristics (10 kHz–1 MHz). Due...
A tunable dual-band metamaterial filter based on crossed split-ring resonators is numerically and experimentally demonstrated. The proposed consists of two same metal split rings with different angles. Based the cross-coupling between these rings, stopbands are generated. Moreover, operating frequency can be tuned by changing angle rings. In context numerical results, surface current distributions electric field were employed to analyze basic principle, experiments performed demonstrate...
Abstract It is challenging to measure the electron density of unsteady plasma formed by charged particles generated from explosions in air, because it transient and on a microsecond time scale. In this study, time-varying small cylindrical cyclotrimethylenetrinitramine (RDX) explosion air was measured, based principle microwave Rayleigh scattering. found that evolution related diffusion detonation products. The application scattering an attempt estimate explosively plasma. Using equivalent...
An underwater explosion experiment was designed for the cyclotrimethylenetrinitramine-based aluminized explosives to study influence of detonation conditions on performance and afterburn reaction aluminum (Al) particles. The research results showed that shock wave bubble pulsation grew stronger under overdriven (ODD), contribution ODD energy associated with proportion inner core outer coat. Considering propagation characteristics in ordinary charge inner/outer charge, attenuation its role...
Electrostatic accumulation is associated with almost all powder-conveying processes which could bring about electrostatic discharges. In most cases of industrial accidents, discharge proven to be the primary source ignition and explosion. Herein, a surface modification process polyaniline (PANI) proposed construct highly exothermic special powders, namely, HMX@PANI energetic composites, low charge for improving powder safety. Pure HMX are encapsulated within PANI-conductive polymer layer...
Self-supporting electrodes usually show excellent electrocatalytic performance which does not require coating steps, additional polymer binders, and conductive additives. Rapid in situ growth of highly active ingredient on self-supporting electric conductors is identified as a straight forward path to prepare binder-free integrated electrodes. Here, Pd-doped Co3O4 loaded carbon nanofiber materials through electrospinning heat treatment was efficiently synthesized, used free-standing...
Compact pulse generators which utilized soft ferromagnets as an initial energy carrier inside multi-turn coil and hard to provide the magnetic field outside have been studied. Two methods of reducing flux in studied: (1) by igniting gunpowder launch core out generator, (2) detonating explosives that demagnetize core. Several types compact were explored verify feasibility. The with 80-turn utilize capable producing pulses amplitude 78.6 V full width at half maximum was 0.41 ms. a 37-turn...
There is confinement of a bubble that provides long time for the afterburn reaction aluminum (Al) additives when aluminized explosives explode in water, and information reflected by dynamic behaviors bubble. In this study, energy partition RDX-based with different Al content was obtained an underwater explosion experiment, influence on accelerating expansion, decelerating contraction revealed. It found pressure these stages changed content, leading to variation process releases energy. Based...
