Abstract Hydrogels are widely used in flexible aqueous batteries due to their liquid‐like ion transportation abilities and solid‐like mechanical properties. Their potential applications wearable electronics introduce a fundamental challenge: how lower the freezing point of hydrogels preserve these merits without sacrificing hydrogels' basic advantages low cost high safety. Moreover, zinc as an ideal anode suffers from reversibility because formation insulative byproducts, which is mainly...
This paper presents the performance of a new magnetorheological elastomer-based semi-active/passive variable stiffness and damping isolator (VSDI) in scaled building system. The force VSDI can be controlled real time by varying applied magnetic field. To demonstrate VSDI, four prototypes are built utilized three-story building. A Lyapunov-based control strategy is employed it demonstrated that works well for system under El Centro earthquake motion. Experimental results show VSDIs...

In nature, many plants have evolved various wettability surfaces to survive and thrive in diverse environments. For example, the superhydrophobic surface of lotus can keep itself clean, while rose petals retain droplets for a long time. The former is referred "lotus effect," latter known as "rose petal effect." This research proposes method fabricate magnetic-responsive magnetorheological elastomers (MREs) which could reversibly instantly transition their wetting state between effect" These...
For large area robot skin design, the distribution of rigid components and wires in traditional array sensors leads to decrease flexibility extensibility sensors. The flexible based on non-invasive electrical impedance tomography (EIT) can avoid these shortcomings. However, design a large-area tactile using EIT technique is still challenging due tradeoff between manufacturability spatial resolution. In this study, we proposed novel non-array EIT-based sensor which made porous elastic polymer...

Two-dimensional (2D) metal oxides exhibit extraordinary mechanical and electronic properties, leading to new paradigms in the design of optical systems. However, as a representative, 2D Ga2O3-based memristor has rarely been touched, which is hindered by challenges associated with large-scale material synthesis.

The Bingham plastic constitutive model has been widely used to predict the post-yield behavior of electro- and magneto-rheological fluids (ER MR fluids). However, if these experience shear thinning or thickening, may not be an accurate predictor behavior, since viscosity is assumed constant. In a recent study, it was theoretically experimentally demonstrated that Herschel-Bulkley fluid can successfully employed when evaluating non-Newtonian ER fluids. this paper, we extend our previous work...
