Interaction of ultrasonic waves with damage by exploiting the transmission of digital data using guided waves: application to smart vehicle

Rudy Bahouth, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

This work aims to compromise between Structural Health Monitoring and information transmission through solid channels mainly for the application of smart vehicles. The purpose of such idea is to transmit digital data of a sensor without using any wires in one hand, and, inspecting defects in many...

Micro-transducers matrix design for structural health monitoring

Hala El Rammouz, Farouk Benmeddour, Jamal Assaad, Emmanuel Moulin, Youssef Zaatar, Ziad Herro

In this work, a two-dimensional (2D) Lithium Niobate (LiNbO3) 36°Y-cut micro-transducers (μTs) matrix design is presented. Two main steps define the fabrication process: electrode deposition and photolithography. These steps are preceded by the optical mask conception, which defines the 2D matrix...

Internet of things system for healthcare applications

Prasaja Wikanta, Andy Triwinarko, Iyad Dayoub, El Hadj Dogheche

The IoT sensor networks used by patients, could support medical staff to diagnose and to monitor continuously. The human body and movement can cause interference which make the sensors retransmit the data. This will increase packet error ratio (PER). Our cross layer protocol take advantages of...

Baseline-free repetitive pump-probe experiment for structural health monitoring

Marina Terzi, Lynda Chehami, Emmanuel Moulin, Nikolay Smagin, Vladislav Aleshin

Baseline-free damage localization methods in structural health monitoring are of interest. We conducted a pump-probe experiment on metal plate. PZT patch generates a probe wave at 20 kHz, a continuous pump of 1 Hz is produced by a shaker. The aim was localization of a steel ball pressed against...

High voltage excitation and nonlinear transmission of a 16 MHz AlN-based piezoelectric micro-machined ultrasonic transducer

Wen-Juan Liu

This paper reports a 16 MHz AlN-based piezoelectric micro-machined ultrasonic transducer (PMUT) under high voltage excitation. The proposed PMUT array consists of 44x39 elements fabricated on a silicon-on-insulator (SOI) substrate with 1 μm AlN film on 5 μm silicon membrane. The electrical...

Dual sensing and actuation of ultrathin conducting polymer transducers

Tan Ngoc Nguyen, Cedric Plesse, Frederic Vidal, Sébastien Grondel, Eric Cattan, John D.W. Madden

Conducting polymers are active materials that exhibit an interesting bidirectional electromechanical coupling, where an input voltage results in the displacement of the film and a voltage is produced when a displacement is applied to the film. Mechanical deformation of the transducer by external...

Improved facial expression recognition based on DWT feature for deep CNN

Ridha Bendjillali, Mohammed Beladgham, Khaled Merit, Abdelmalik Taleb-Ahmed

Facial expression recognition (FER) has become one of the most important fields of research in pattern recognition. In this paper, we propose a method for the identification of facial expressions of people through their emotions. Being robust against illumination changes, this method combines four...

A Sub-35 pW Axon-Hillock artificial neuron circuit

Francois Danneville, Christophe Loyez, K. Carpentier, I. Sourikopoulos, E. Mercier, A. Cappy

Artificial Intelligence (AI) applications are developing at a high rate, facing soon a tremendous energy challenge. In this context, the original Axon-Hillock (AH) Artificial Neuron (AN) has been optimized to achieve ultra-low power (ULP) consumption. The membrane capacitance was taken out, and in...
