Within the framework of a project consisting in developing a haptic keyboard, each key is aimed to be controlled individually in position and force. Small sized actuators has already been designed and integrated in a 64 keys force feedback keyboard. The pr ...
This project was done in the laboratory of integrated actuators (LAI) during the first master semester. It is part of a PhD-work with linear actuators, also called relays, where these actuators are optimized in design and equipped with a speed control duri ...
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 moving part. A sinusoidal scan voltage is super ...

In the scope of haptic touch feedback actuators, we discuss the phenomenon of creating the haptic experience by squeezing the air film between the user finger and the actuator. The focus is given in the modeling of the squeeze film effect. An existing anal ...
The goal of the project is to explore the possibility of controlling the speed of the actuator’s moving part without using any sensor. The speed has to be set accordingly to the position of the moving part at specific time. This dependency is fixed and is ...
The scope of this work has been the design of a mechanical actuator in polydimethylsiloxane (PDMS) / glass for precise liquid sampling, based on the electrochemical generation of O2. The device is composed of two chambers separated by a PDMS membrane. In t ...
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 ...
Functional Magnetic Resonance Imagery (fMRI) is an imaging technique allowing the observation of brain activity. Haptic interfaces can be used in conjunction with fMRI to stimulate the subject while measuring brain activity. Using robotic stimulation over ...
