Study 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 ...

Duct 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 ...

Analysis of local deformation effects in resistive strain sensing of a submicron-thickness AFM cantilever

Georg Fantner, Jonathan David Adams, Maja Dukic Pjanic

Incorporating resistive strain-sensing elements into MEMS devices is a long-standing approach for electronic detection of the device deformation. As the need for more sensitivity trends the device dimensions downwards, the size of the strain-sensor may bec ...

Piezoresistive 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 ( ...

Use of self-actuating and self-sensing cantilevers for imaging biological samples in fluid

Georg Fantner

In this paper, we present a detailed investigation into the suitability of atomic force microscopy (AFM) cantilevers with integrated deflection sensor and micro-actuator for imaging of soft biological samples in fluid. The Si cantilevers are actuated using ...

Fluctuations de l'aimantation induites par des courants de haute densité dans des vannes de spin électrodéposées

Andrea Fabian Montabert

Copper wires each one containing a pseudo-spin valve of Co/Cu/Co were produced by electrodeposition inside nanoporous polycarbonate membranes. These wires have a diameter of 40 nm and a length of 6000 nm of which only 50 nm relates to the spin valve. In or ...
