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...

Cross-layer design (PHY/MAC/NET) for vehicular ad-hoc networks (VANETs)

Andy Triwinarko, Iyad Dayoub

The MAC protocol of IEEE 802.11p dedicated to vehicular ad-hoc networks (VANETs) is using Distributed Coordination Function (DCF) that prohibits simultaneous transmissions in the same detection area in order to avoid interference between neighboring vehicles. This prohibition causes a temporary...

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...

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...
