Recently, LTCC (low-temperature co-fired ceramic) technology has increasingly found applications beyond pure electronics, in fields such as microfluidics, sensors and actuators, due to the ease of shaping the tapes in the green (unfired) state. Accurate co ...
Joint simulators are widely used to perform pre-(and post) clinical test of joint prostheses. Several experimental or commercial devices already exist for the hip and knee joints, but nothing is available yet for the shoulder joint. The first goal of this ...
While dealing with sub-micrometer precision robots, thermal expansion is the most significant source of inaccuracy. Thermal variations in the environment, in the robot parts and in the frame change the robot geometry, lowering the robot precision. In this ...
In this paper, we propose to derive an analytical model for the doped symmetric double-gate (DG) MOSFET that is valid in all regions of operation. We show that doping the silicon channel can be converted in an equivalent silicon thickness and threshold vol ...
Milling is a most common type of material removal process by rotating tools to create a variety of features on a part. The material is removed in a controlled way by sweeping a rotating cylindrical tool along the specific trajectory known as milling tool p ...
We have investigated the motion of a single optically trapped colloidal particle close to a limiting wall at time scales where the inertia of the surrounding fluid plays a significant role. The velocity autocorrelation function exhibits a complex interplay ...
This paper presents a method for the analysis of planar multilayered waveguide-fed antennas. The method combines mixed-potential integral equations (for laterally open regions) and modal field integral equations (for laterally closed regions) with a seamle ...

Within the framework of a project consisting in developing a novel haptic computer keyboard, force and position control is required for each key. The previous project phase consisted in the design and optimization of a miniature actuator which is to be ins ...
We present the numerical optimization of GaN-based embedded 2D-Photonic Crystal (PhC) LEDs based on a full 3D scattering matrix model pointing out the importance of a proper vertical design in embedded PhC structures. The growth of such structures followin ...
This paper addresses the design and optimization of a small-sized linear electrodynamic actuator. This actuator is aimed to be inserted under a computer key in order to produce a force feedback to the user. Replacing the current rubber dome supporting the ...
