Experimental investigation of a digital electromechanical system to measure soil bulk density in a silty clay soil under different solarisation practices Ghent University
A digital electromechanical system (DES) is an innovative system for in situ measurement of soil dry bulk density (ρb) based on microwave drying of automatically collected core samples. This paper determines the effectiveness of DES for measuring soil ρb in a silty clay soil under solarisation conditions. The experimental design consisted of 2 by 2 m plots arranged in a split-plot design with systematic plot arrangement, and three replicates ...
SystemC-AMS modeling of an electromechanical harvester of vibration energy Ghent University
This paper presents the results of modeling of a mixed non-linear, strongly coupled and multidomain electromechanical system designed to scavenge the energy of ambient vibrations and to generate an electrical supply for an embedded microsystem. The system is operating in three domains: purely mechanical (the resonator), coupled electromechanical (electrostatic transducer associated with the moving mass) and electrical circuit, including ...
Electromechanical factors associated with favourable outcome in cardiac resynchronization therapy Vrije Universiteit Brussel
AIMS: Electromechanical coupling in patients receiving cardiac resynchronization therapy (CRT) is not fully understood. Our aim was to determine the best combination of electrical and mechanical substrates associated with effective CRT.
METHODS AND RESULTS: Sixty-two patients were prospectively enrolled from two centres. Patients underwent 12-lead electrocardiogram (ECG), cardiovascular magnetic resonance (CMR), echocardiography, and ...
Effect of Secondary Particles on Self-Healing and Electromechanical Properties of Polymer Composites Based on Carbon Black and a Diels-Alder Network Interuniversity Microelectronics Centre
The addition of an organomodified nanoclay to a carbon-based electrically conductive self-healing composite showed a synergistic improvement of the electrical conductivity and self-healing ability of the formed hybrid composites. The effect on the electrical, viscoelastic, and self-healing properties was studied for Diels-Alder-based reversible polymer networks with a maleimide-to-furan stoichiometric ratio of 0.6, with different loadings of ...
Electromechanical Equivalent Circuit Model for Axisymmetric PMUTs With Elastic Boundary Conditions KU Leuven
Electromechanical Equivalent Circuit Model for Axisymmetric PMUTs With Elastic Boundary Conditions Interuniversity Microelectronics Centre KU Leuven
Here we present an electromechanical lumped equivalent circuit model for the purpose of deriving the electrical input impedance and response of air-coupled axisymmetric polymer-based piezoelectric micromachined ultrasonic transducers (pMUT). In particular, this study presents the derivation and validation of polyvinylidene fluoride-co-trifluoroethylene P(VDF-TrFE) unimorph pMUT equivalent circuit models operating in the fundamental axisymmetric ...
Experimental and numerical study of a piezoelectric diaphragm, a smart sensor for electromechanical impedance-based structural health monitoring Ghent University
One of the promising techniques for online damage monitoring of structures is the electromechanical impedance (EMI) based method. This method uses the electrical admittance of a piezoelectric transducer to detect damage. A piezoelectric diaphragm consisting of a circular piezoelectric material laid on a brass circular thin electrode is a favorable transducer. Although the brass electrode makes the installation of the transducer easy, it affects ...
