Bending stiff charged polymers: The electrostatic persistence length [PDF]

open access: yesEPL (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.

Joint Stiffness Identification of a Heavy Kuka Robot with a Low-cost Clamped End-effector Procedure [PDF]

open access: yes, 2014
This paper proposes two new methods for the identification of static stiffnesses of multi degrees of freedom heavy industrial robots. They are based on a locked link joint procedure obtained with an end-effector fixed to the environment. The first method

Measurement of Flow Characteristics in a Bubbling Fluidized Bed Using Electrostatic Sensor Arrays [PDF]

open access: yes, 2016
Fluidized beds are widely applied in a range of industrial processes. In order to maintain the efficient operation of a fluidized bed, the flow parameters in the bed should be monitored continuously. In this paper, electrostatic sensor arrays are used to

Smooth boundary topology optimization applied to an electrostatic actuator [PDF]

open access: yes, 2008
Smooth boundary topology optimization (SBTO) avoids many of the problems encountered by conventional cell based systems coupled with material homogenization or density method. Shape optimization becomes part of topology optimization. The effectiveness of

Electrostatic layer jamming variable stiffness based on AC waveform regulation

open access: yesJournal 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 ...
