In this paper, an improved design of a silicon micromachined gyroscope (angular rate sensor) is presented. It is based on the tuning fork principle and realized by combining two proof masses. The gyroscope is driven by electromagnetic forces and detects th ...
The objective of this feasibility study is to evaluate the use of the 'Physilog' device, an ambulatory physical- activity recorder based on acceleration measurement, for the monitoring of daily physical activities. Accelerations measured at the level of th ...
In this paper the simple accelerometers based on PZT thin films were developed and characterized. The functions of seismic mass and spring are given by a boss loaded cantilever structure. The strain of the cantilever is detected by a Pb(Zr,Ti)O-3 thin film ...
The project presented in this paper aims at defining the limits of microsystems through the realisation of a navigation system based on inertial microsensors. The work includes (i) design, fabrication, characterisation of accelerometers and angular rate se ...
A new method for the detection of gait cycle phases using only two miniature accelerometers together with a light, portable digital recorder is proposed. Each subject is asked to walk on a walkway at his/her own preferred speed. Gait analysis was performed ...
In earlier studies we found that the three-element windkessel, although an almost perfect load for isolated heart studies, does not lead to accurate estimates of total arterial compliance. To overcome this problem, we introduce an inertial term in parallel ...
In networked virtual environments (NVEs), users are represented by their virtual embodiments. The articulated structure of these embodiments introduces a new complexity in the representation and streaming of animations, especially when the number of partic ...
Airborne gravimetric and altimetric measurements depend heavily on the determination of the instantaneous position and attitude of the aircraft. Here, a methodology to process raw inertial data together with GPS data collected from at least two antennas/re ...
An entire microsystem for high accuracy magnetic field measurement based on vertical Hall devices has been simulated. In accordance with existing knowledge about semiconductor physics and experimental results, a functional SPICE- model for a vertical Hall ...
A method to evaluate capacitance based on parameter extraction from finite- element analysis as well as a global model for a novel silicon microfabricated accelerometer are presented. Mechanical simulations have been performed and results are coupled with ...
