Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

The design of repulsive electrostatic actuators having enlarged travel range is achieved by combining the boundary element approach and a genetic algorithm. method enables calculating forces without time consuming finite simulations. Once static equation that uses model effective lumped mass solves ranges, GA maximizes ranges optimizing dimensional parameters. effectiveness scheme demonstrated ...

Biodegradable materials decompose and return to nature. This functionality can be applied derive robotic systems that are environmentally friendly. study presents a fully biodegradable soft actuator, which is one of the key elements in “green” robotics. The working actuator based on an electrohydraulic principle, similar hydraulically amplified self-healing electrostatic actuators. developed th...

The objective of current paper is 3D simulation of turbulent, developing flow and unsteady within a circular duct in presence of the body force vector persuaded by Dielectric barrier discharge (DBD) plasma actuator inside the surface of geometry for the first time. This article aims at investigating of applying plasma actuator to control separation with special arrangement of electrodes. For th...

Pressure-driven actuators play a critical role in many microfluidic technologies, but the ancillary equipment needed to operate pneumatic and hydraulic platforms has limited their portability. To address this issue, we created an electrostatic microvalve used to regulate pressures in hydraulic control lines. In turn, these control lines are able to actuate pressure-driven components, e.g., micr...

Drag-free technology functions as the keystone for space-based gravitational wave detection satellites moving along a geodesic path, like Laser Interferometer Space Antenna (LISA) Pathfinder, to achieve ultra-high microgravity level. Several prerequisites micro-thrusters operated under drag-free technique include constantly adjustable thrust, high resolution, low noise and fast response time. A...
