Contactless Excitation of MEMS Resonant Sensors by Electromagnetic Driving
A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as ... Per saperne di più
Droplet Generation by Means of a Two-Fluid Probe
This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn ...

Control of Rolling Direction for Released Strained Wrinkled Nanomembrane
Strained wrinkled and flat nanomembranes have different bending properties when they are released from the underlying substrate. This is caused by increased bending rigidity of the wrinkled film in one direction. We provide theoretical and numerical analysis of the directional rolling of ... Per saperne di più
Thickness Optimization of a Piezoelectric Converter for Energy Harvesting
The conversion of mechanical energy from environmental vibrations into electrical energy is a key point for powering sensor nodes toward the development of autonomous sensor systems. Piezoelectric energy converters realized in a cantilever configuration are the most studied for this ... Per saperne di più
Multiphysics Modelling of a Micro Valve
Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... Per saperne di più
Analog to Digital Microfluidic Converter
This paper presents an Analog to Digital Microfluidic Converter (ADMC) using passive valves and enabling the conversion of a continuous liquid flow into droplets for Electro-Wetting On Dielectric (EWOD) actuation. Valves calibration, geometry characteristics and losses reduction have ... Per saperne di più
Transient Simulation of a Naturally Ventilated Façade in a Mediterranean Climate
Energy performances and building energy quality can be achieved by high performance envelopes. In this paper the thermal performance of a naturally ventilated façade, applied to a traditional wall, widely used in existing buildings, was investigated by a transient simulation. A ...

Helium Two-Phase Flow in a Thermosiphon Open Loop
The construction of high magnetic field superconducting coils requires the use of low temperature superconductors that must be cooled down to liquid helium temperature (4.2 K). Natural two-phase convection loops, i.e. thermosiphon loop, are used as cooling system for large ... Per saperne di più
Helical Coil Flow: A Case Study
Stationary flow configurations in curved pipes constitute an important subject from both the theoretical and the practical point of view. A typical application concerns the calculation of secondary flow effects on the thermal efficiency of heat exchangers. Motivated by a similar problem, ... Per saperne di più
Laminar Thermal Mixing in Coating Flows
Heat transfer in a plane shear flow configuration consisting of two infinitely long parallel plates is considered. In laminar flows over undulated substrates eddies can be generated due to the kinematical constraints. A closed form analytical solution for the velocity field, based on ... Per saperne di più
