Measurement-system design for structural identification
In developed countries, the management of existing civil infrastructure is challenging due to evolving functional requirements, aging and climate change. Due to conservative approaches in construction design and practice, infrastructure often has hidden re ...
EPFL2020Study of self-sensing actuation strategies for quasi-static piezoelectric actuators
Yves Perriard, Louis Antoine Masson
Self-sensing actuation in piezoelectric actuators has been a growing research topic since 1992, with two main approaches having been identified: either by evaluating the dielectric displacement field within the piezoelectric through a measurement bridge, e ...
IEEE2019Duct modes damping through an adjustable electroacoustic liner under grazing incidence
Hervé Lissek, Romain Boulandet, Gaël Matten
This paper deals with active sound attenuation in lined ducts with flow and its application to duct modes damping in aircraft engine nacelles. It presents an active lining concept based on an arrangement of electroacoustic absorbers flush mounted in the du ...
2018Piezoresistive n-Type 4H-SiC Pressure Sensor with Membrane Formed by Mechanical Milling
Nico de Rooij, Danick Briand, Terunobu Akiyama
A 4H-SiC pressure sensor with piezoresistive transducers, for harsh environment applications, e.g., high temperature (~650°C) and/or in corrosive chemicals is presented. The sensing membrane, 1 mm in diameter and 50 µm in thickness, was formed by milling ( ...
