Contact and non-contact based atomic force microscopy (AFM) approaches have been extensively utilized to explore various nanoscale surface properties. In most AFM-based measurements, a concurrent electrostatic effect between the AFM tip/cantilever and sample surface can occur. This electrostatic effect often hinders accurate measurements. Thus, it is very important to quantify as well as remove...

Electrostatic adhesion technology has broad application prospects on wall climbing robots because of its unique characteristics compared with other types of adhesion technologies. A double tracked wall climbing robot based on electrostatic adhesion technology is presented including electrode panel design, mechanical structure design, power supply system design a...

The concept of dry surface treatment for paper coating applications has been available for more than ten years. Different from conventional coating methods such as extrusion coating and suspension coating, dry surface treatment involves a combined process of non-contact deposition of coating materials and surface smoothening of the coated paper. Pronounced features of this concept include avoid...

This paper presents a feasibility study for applying electrostatic actuators on wall climbing robot (WCR). These film actuators have generated useful level of attachment force on vertical wall surface. It works on non-conductive surface such as ceramic tiles. The confirmed advantages of electrostatic adhesion are encouraging for the development of WCR. Design considerations for the WCR are also...

The nonlinear electrostatic pull-in behaviour of MEMS Switches in micro-electromechanical systems (MEMS) is investigated in this article. We used the distributed model when the electrostatic pressure didn’t apply at the whole of the beam and applied only in the mid-part of the beam. In this part the electrostatic area is different from two other parts. The model uses Euler-Bernoulli beam theory...

Among various devices for removing submicrometer particles from a gas stream, fibrous filters have the advantages of providing high collection efficiencies at low-pressure drop. Even in the absence of electrostatic forces, a fibrous filter captures particles efficiently by inertial impaction, interception, and convective Brownian diffusion. Application of electrostatic forces can significantly ...

Electrostatic sensor, which can also be called as triboelectric sensor or electrodynamic sensor, senses the electrostatic charge carried by the dry particle in pneumatic conveyor. Source of the signal induced on the electrostatic sensor is brought by the object to be measured and no excitation circuit is necessary. Electrostatic sensors are used in the process industry due their low cost and ro...
