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…

Binary sessile drops evaporation: IR and acoustic methods for alcohol concentration tracking at the interface and the surface

Pin Chen, Malika Toubal, Julien Carlier, Souad Harmand, Bertrand Nongaillard, Maxence Bigerelle

Evaporation process of droplets of three pure liquids (water, 1-butanol, and ethanol) and four binary solutions (5 wt % 1-butanol water-based solution and 5, 25, and 50 wt % ethanol−water-based solutions) deposited on hydrophobic silicon substrate was studied under ambient condition. An optical…

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…

Micro air vehicle to nano air vehicle : theoretical and experimental studies of an artificial flapping insect, Du micro véhicule aérien au nano véhicule aérien : études théoriques et expérimentales sur un insecte artificiel à ailes battantes

Le Anh Doan

In recent decades, the prospect of exploiting the exceptional flying capacities of insects has prompted much research on the elaboration of flapping-wing nano air vehicles (FWNAV). However, when designing such a prototype, designers have to wade through a vast array of design solutions that…, Au cours des dernières décennies, la possibilité d’exploiter les capacités de vol exceptionnelles des insectes a été à l’origine de nombreuses recherches sur l’élaboration de nano-véhicules aériens (NAVs) à ailes battantes. Cependant, lors de la conception de tels prototypes, les chercheurs doivent…
