Electronic door lock cylinders need some sort of mechanical actuator to toggle the locking state between open and closed. The main requirements are high security standards, low power consumption, reasonable production costs, and facile integration of the a ...
This paper presents an initial state of the art about the estimation of the sound power emitted by electrical machines. The paper proposes a new method, more accurate, to evaluate the sound power emitted by a PM machine by a 3D FEM mechanical analysis. It ...
A digital controller for piezoelectric motors was developed. The controller tunes the driving frequency in order to maximize the power transmitted to the motor. A maximum of power is absorbed when the resonant frequency of the mechanical and electrical par ...
A mobile microrobot is defined as a robot with a size ranging from 1 in3 down to 100 µm3 and a motion range of at least several times the robot's length. Mobile microrobots have a great potential for a wide range of mid-term and long-term applications such ...
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 ...
Piezoelectric motors are particular motors converting electrical energy into mechanical movement, based on the inverse piezoelectric effect. Piezoelectric material, when electrical field applied, produces acoustic or ultrasonic vibrations. These vibrations ...
This paper describes the development of a 2-DOF electrostatic haptic joystick designed for neuroscience studies in an MRI/fMRI. The joystick is fabricated using non-magnetic materials and actuated by two high-power electrostatic motor units which produce v ...
The goal of this semester project is to study and design such a vibrating key. This report is meant not only to describe a particular vibrating key, but also to serve as a basis for anyone who would want to design one. In this idea, sensing and actuating t ...
This paper presents a safe, electrically powered MR-compatible actuator with a large range of output impedance, which can be used at the entry of the scanner bore. This actuator is composed of an ultrasonic motor (USM) and a torque-controlled electrorheolo ...
