Owing to their high deformation ability, 4D printed structures have various applications in origami structures, soft robotics and deployable mechanisms. As a material with programmable molecular chain orientation, liquid crystal elastomer is expected produce the freestanding, bearable deformable three-dimensional structure. However, majority of existing printing methods for elastomers can only fabricate planar which limits designability bearing capacity. Here we propose direct ink writing...
A vibration energy harvesting generator was studied in the present research using point-defect phononic crystal with piezoelectric material. By removing a rod from perfect crystal, resonant cavity formed. The elastic waves range of gap frequencies were all forbidden any direction, while frequency localized and enhanced cavity. collected converted into electric by putting polyvinylidene fluoride film middle defect. This structure can be used to simultaneously realize both damping...

Stretchable strain sensors play a key role in motion detection and human-machine interface functionality, deformation control. However, their sensitivity is often limited by the Poisson effect of elastic substrates. In this study, stretchable sensor based on continuous-fiber-reinforced auxetic structure was proposed fabricated using direct ink writing (DIW) 3D printing process. The application multi-material DIW greatly simplifies fabrication process with an (auxetic sensor). auxiliary...
Abstract A modular design method is introduced to an acoustic metamaterial based on nested Helmholtz resonators that target low‐frequency sound attenuation.
