This paper presents a method to detect the position of a linear actuator without any position sensor. The actuator winding has a resonance frequency that is very related to the position of the linear actuator Pmoving part. A sinusoidal scan voltage is supe ...
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 ...
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 ...
This diploma project’s goal was to develop a low-cost 3 DOF position sensor of small dimension that permits to find the position and orientation of the actuated object and thus, enable a closed loop control in 3 DOF. The range in X and Y should be at least ...
A fundamental step towards achieving an "on demand" single photon source would be the possibility of electrical pumping for a single QD and thus the integration of such a device in an opto-electronic circuit. In this work we describe the fabrication proces ...
Patterning of micro- and nanometer scale structures by means of nanostencils (shadow masks) is increasingly being used as a simple, clean and low-cost alternative to photolithography. Currently, large area pattern transfer using nanostencil lithography is ...
We have fabricated and characterized a polymethylmethacrylate (PMMA) valveless micropump. The pump consists of two diffuser elements and a polydimethylsiloxane (PDMS) membrane with an integrated composite magnet made of NdFeB magnetic powder. A large-strok ...
The present invention discloses a device (CD) for converting a first motion (x s ) into a second motion ( y) responsive to said first movement (x s ) under a demagnification scale (i), comprising: a) an input portion (IP) being drivable in a rectilinear tr ...
We present the microfabrication and characterisation of a ball valve micropump in glass, which is magnetically actuated using the sinusoidal current of an external electromagnet. We employ the use of a simple powder blasting technology for microstructuring ...
From electrochemical measurements at the interface of two immiscible electrolytes, the current at controlled potential is usually a linear function of the ion concentration in the aqueous phase. Surprisingly, a linear relationship between the current and t ...
