We investigate the use of a piezoelectric actuator for the appendages of a microrobot. Possible uses may include micro assembly, mobile surveillance, etc. What is different about this microrobot is that it uses 2 degrees of freedom, low powered piezoelectric flexures, while attempting to ...

Modeling of 3D AC electro-osmotic pumps is relevant to the creation of portable or implantable lab-on-a-chip devices for mm/s tunable fluid flows attainable with battery scale voltages. In this analysis using COMSOL Multiphysics we investigate the modeling challenges of computationally ... Per saperne di più
The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... Per saperne di più
In our recent experiments we are revisiting the topografiner technology for the imaging of surface topography with a resolution of a few nanometers. In these new technique called Near-Field Emission Scanning Electron Microscopy (NFESEM), low-energy electrons are emitted from a ... Per saperne di più
Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero ... Per saperne di più
The shear mode of film bulk acoustic resonators (FBARs) is preferred to the longitudinal mode owing to its lower acoustic losses in a liquid. However in addition to mass loading, the resonance is also affected by temperature and liquid viscosity. These two parameters can either be sensed ... Per saperne di più
Plasmons, i.e. the collective oscillations of electrons in a metallic nano-structure, lead to strong light scattering, absorption and an enhancement of the local electromagnetic field. In this work, the local electric-field enhancement in a system of dielectric nanoparticles placed ... Per saperne di più
Usually, in integrated circuits, the chip is brazed on leadframe and then, a polymer resin is molded around to create the packaging. On the first hand, the molding process at high temperatures will induce thermomechanical stress on the chip. As the leadframe, the chip and the braze have ... Per saperne di più
Viscous damping has a significant effect on dynamic performance of the resonators operating within fluid. This work is aimed to find the viscous damping for MEMS torsional paddle operating in air. Interaction of moving structure with the fluid requires a complicated and challenging ... Per saperne di più
A COMSOL Multiphysics® simulation was used to simulate the behavior of a micro-membrane (Acoustic Pixel) to be used as a potential acoustic transducer. The MEMS and Piezoelectric devices interfaces were used to simulate such transducer. A four-cantilever spring configuration is initially ... Per saperne di più
