With the rapid development of human–machine interactions and artificial intelligence, demand for wearable electronic devices is increasing uncontrollably all over world; however, an unsustainable power supply such sensors continues to restrict their applications. In present work, piezoelectric barium titanate (BaTiO3) ceramic powder with excellent properties was prepared from milled precursors through a solid-state reaction. To fabricate flexible device, as-prepared BaTiO3 mixed...
A systematic investigation was implemented in this work to evaluate the effect of hygrothermal aging on chemistry, mechanics and morphology a toughened epoxy resin exposed 70°C bath. This system reached equilibrium moisture absorption within 2530 h with saturation water uptake 3.6%, diffusion displayed non-Fick behavior, but can be illuminated well by Langmuir model. The influence glass transition temperature (Tg) evaluated Differential Scanning Calorimetry. Chemical changes were monitored...
A comprehensive computational micromechanics has been presented to predict the transverse mechanical properties and failure envelop of bi-axial stress in a 22-33 plane at high temperatures. First, paraboloidal elasto-plastic damage model considering temperature effect epoxy employed. Then, order rapidly create random fiber distribution representative volume element (RVE), simple effective algorithm placement an auto modeling calculating python script have developed, where thickness size RVEs...
The longitudinal compressive behavior of the three-dimensional four-step braided composites after cyclic hygrothermal aging was investigated using a split Hopkinson pressure bar (SHPB) apparatus under high strain rates (1100~1250 s−1, 1400~1600 1700~1850 respectively). SEM micrographs were examined to damage evolution aging. A high-speed camera employed capture progressive process for composites. results indicate that saturated moisture absorption not reached during whole 210 days. mainly...
As a kind of important functional materials, flexible piezoelectric materials have the advantages good toughness, high plasticity and light-weight.The can realize effective conversion between mechanical energy electrical energy, it be attached to human body obtain or environment information in real time, thereby widely used motion detection, health monitoring, computer interaction.With requirements various there dimensional (3D) structures additive manufacturing has been extensively utilized...
