Variable stiffness sandwich panels using electrostatic interlocking core [PDF]
SPIE Proceedings, 2016 Structural topology has a large impact on the flexural stiffness of a beam structure. Reversible attachment between discrete substructures allows for control of shear stress transfer between structural elements, thus stiffness modulation. Electrostatic adhesion has shown promise for providing a reversible latching mechanism for controllable internal ...

Key Engineering Materials, 2011 The main advantage of a resonant accelerometer based on electrostatic stiffness over other sensing principles is it can make use of the sensing voltage to adjust the sensitivity. The dynamic model of this accelerometer is built. With the aim to achieve the resonance frequency track, a phase-locked loop(PLL) system is used to track the resonance ...

Structure Design and Experiment for a Resonant Accelerometer based on Electrostatic Stiffness
Key Engineering Materials, 2011 The introduced resonant accelerometer makes use of the equivalent electrostatic stiffness to sense the acceleration. The sensitivity can be adjusted by changing the applied sensing voltage. But the no-linearity problem between the output frequency and applied acceleration is difficult to calculate the sensitivity and analysis its influence directly ...

Electrostatic layer jamming variable stiffness based on AC waveform regulation [PDF]
Journal of Physics: Conference Series, 2023 Abstract As a method to achieve variable stiffness of soft robots, electrostatic layer jamming (ELJ) has the disadvantages of low breakdown strength and a single stiffness control method. In this paper, we propose to replace the air of the traditional ELJ device with giant electrorheological fluid (GERF) and introduce the method of ...

Bending stiff charged polymers: The electrostatic persistence length [PDF]
EPL (Europhysics Letters), 2016 Many charged polymers, including nucleic acids, are locally stiff. Their bending rigidity -- quantified by the persistence length --, depends crucially on Coulombic features, such as the ionic strength of the solution which offers a convenient experimental route for tuning the rigidity.

Electrostatic Contributions to Chain Stiffness and Excluded-Volume Effects in Sodium Hyaluronate Solutions [PDF]
Polymer Journal, 1996 Intrinsic viscosities [η] for sodium hyaluronate in aqueous sodium chloride at 25°C were determined for 12 samples ranging in weight-average molecular weight Mw from 3.8×103 to 3.5×105 at NaCl concentrations Cs between 0.005 and 2.5 M. They were analyzed on the basis of the Yamakawa-Fujii-Yoshizaki theory for [η] of an unperturbed wormlike chain ...
