We report the fabrication of silicon microcantilevers with MOSFET detection, to be used in force measurements for biomolecular detection. Thin cantilevers are required for a high force sensitivity. Therefore the source and drain of the transistors have bee ...
The present thesis is devoted to a detailed study of the Casimir force exerting between two parallel metallic plates whose conducting behaviour is described on the microscopic level. In the semi-classical regime, which corresponds to large separations and ...
Atomic force microscopy is being increasingly used to explore the physical properties of biological structures. This technique involves the application of a force to the sample and a monitoring of the ensuing deformation process. The available experimental ...
We report on the mechanical characterization and modeling of a non-prestretched dielectric elastomer diaphragm microactuator with ion-implanted electrodes under the influence of a distributed load (pressure). Thin polydimethysiloxane (PDMS) membranes (30 u ...
We present an application of the conformal mapping (CM) method to determine the magnetic field and force in an electromechanical actuator. First, we show how to find, using a special type of CM known as the Schwarz-Christoffel mapping, the magnetic field i ...
A reversed shoulder prosthesis is the general treatment of glenohumeral arthritis and concomitant rotator cuff arthropathy. However, failure due to loosening of the components remains a concern. The purpose of this study was to examine the forces that occu ...
The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) pol ...
Ultrasonic motors have received much attention these last years, in particular with regard to their modeling and their design principle. Their operating principle is based on piezoelectric ceramics that convert electrical energy into mechanical energy in t ...
In this paper, we present our on-going work towards grasping in an object manipulation context. Our proposal is a novel method that combines a tubular feature classification algorithm, a hand grasp posture generation algorithm and an animation framework fo ...
The inventive device for measuring forces, in particular radial forces produced on an axis or another piece, for example on the axis of the rear wheel of a motorcycle. Said device comprises a measuring sleeve (1) arranged around an axis (3) in such a way t ...
