Traditional robotic systems have proven to be instrumental in object manipulation tasks for automated manufacturing processes. Object such cases typically involves transport, pick-and-place and assembly of objects using conveyors arms. However, the forces at microscopic scales (e.g., surface tension, Van der Waals, electrostatic) can qualitatively quantitatively different from those macroscopic...

Micromixing is a crucial process within microfluidic systems such as micro total analysis systems (μTAS). A state-of-art review on microstructured mixing devices and their mixing phenomena is given. The review first presents an overview of the characteristics of fluidic behavior at the microscale and their implications in microfluidic mixing processes. According to the two basic principles expl...

Extensive work has been done in the recent years involving use of conventional and passive seismic data for fracture characterization. This is particularly the case with unconventional reservoirs such as shale gas, shale oil and geothermal fields. The purpose of our study is to combine the benefits of conventional seismic data that provides relatively higher resolution reservoir characteristics...

The development of a new passive wireless pressure sensor, based on an electromagnetic transduction approach, is reported. The sensing element is a flexible high resistivity silicon membrane located above a coplanar quarter-wavelength resonator. The comprehensive coverage of the physical bases is beyond the scope of this paper. For the remote extraction of the applied pressure value, the passiv...

This study presents the design, implementation, and assessment of a combined passive active flow control technique with aim increasing aerodynamic performance fixed-wing Micro Air Vehicles (MAVs). Power consumption restrictions in MAVs support choice solutions such as use modified (tubercled) wing leading edge. strategy successfully allows to delay mitigate stall but detrimental effects are fou...

We report an innovative and efficient surgery-like strategy for achieving the coalescence of surfactant-stabilized droplets in microchannels. As pairs of preformed droplets flow across a micro-lancet, with a suitable surface wettability, in a converging microchannel simultaneously, their surfaces are scratched by the micro-lancet, which causes temporarily local scattering of surfactants, and th...

A passive micro strain gauge with a mechanical amplifier has been designed, analyzed, and tested. The mechanical amplifier provides a high gain such that residual strain in thin films can be directly measured under an optical microscope. This strain gauge can be in situ fabricated with active micro sensors or actuators for monitoring residual strain effects, and both tensile and compressive res...
