Abstract Networks of sensors placed on the skin can provide continuous measurement human physiological signals for applications in clinical diagnostics, athletics and human-machine interfaces. Wireless battery-free are particularly desirable reliable long-term monitoring, but current approaches achieving this mode operation rely near-field technologies that require close proximity (at most a few centimetres) between each sensor wireless readout device. Here, we report near-field-enabled...

Significance We show a near–hysteresis-free piezoresistive sensor system from soft materials by using method of generating unique three-dimensional nanoscale crack morphologies on metal-coated elastomeric microstructures. Our addresses the major challenge inherent electromechanical hysteresis faced many electronic skins when large compressive pressures are applied. Piezoresistive sensors made our flexible composite material track deformation with <3% and can be reliably used as healthcare...

Skin-like sensors that transduce tactile pressures and vibrations with minimal environment variation on performance are crucial in robotic sensing prosthetic skins. However, sensor variations under varying environmental conditions, such as temperature humidity, common piezoresistive because of their intrinsic materials properties. Moreover, the viscoelasticity soft elastomers causes strain response a time-dependent fashion, which poses limitations high-frequency tasks, texture recognition....

In this paper, we apply the Double Negative Material in some basic applications, including waveguide, rectangular patch antenna and disc antenna. By analyzing theoretically find that sizes of these equipments can be greatly reduced by using multi-block (which may include both double positive negative material) dielectric materials. addition, antennas are no longer proportional to working frequency but roughly ratio thicknesses slabs. Still new modes waveguide found, at bandwidth dramatically...

Abstract In this paper, the transmission line theory is utilized to characterize metamaterials comprising of microscopic elements a periodic array, specifically, traditional split-ring resonators (SRRs), as an example. The bianisotropic property characterized in new way different from existing wave methods. As evident both simulations and experiments, SRR array structure found be quite lossy even though it made very good conductor or perfect simulation. With present characterization, we are...
