Caused by the influence of triboelectric charges, electrostatic induction in TENG is simply a redistribution of electrons in metal electrodes. As a consequence, promotion of the contact electrification and maximization of the surface triboelectric charge density represents the most fundamental strategy for...
Energy-dissipation elastomers relying on their viscoelastic behavior of chain segments in the glass transition region can effectively suppress vibrations and noises in various fields, yet the operating frequency of those elastomers is difficult to control precisely and its range is narrow. Here, we repo...
The electro-mechanical energy conversion element is provided with an alternating signal to generate a plurality of vibrations, and the plurality of vibrations are combined to generate a driving vibration in the driving portion. An ununiformity of rigidity of the vibration member caused by a ...

The value of the coefficient is rising along with the growing stiffness of the composite.A critical damping ratio is a parameter describing free decaying vibration caused by non-conservative internal friction forces in the contact layer and in the bottom and top layer. The value of the ratio in...
1a), and thirdly the orientational fluctuations caused by bend-libration mixing (Fig. 1d), which all result in a decay of the excitation anisotropy. In isotopically diluted water, the contribution due to intermolecular bend-to-bend energy transfer is suppressed, because of the frequency mismatch ...
the energy increase per cycle decreases rapidly. These effects are caused by the dependence of the charging power on the voltage usto, which is shown inFig. 5e. In the beginning most of the energy is lost due to the low value of usto. The charging power increases as ustoincreases. Afte...
