Human sensing in reverberant environments: RF-based occupancy and fall detection in ships

Marwan Yusuf, Emmeric Tanghe, Brecht de Beelde, Pierre Laly, Matteo Ridolfi, Eli de Poorter, Luc Martens, Davy Gaillot, M. Lienard, Wout Joseph

In this paper, we explore the possibility of estimating the number of people inside a below-deck ship compartment using the theory of room electromagnetics. Most RF-based occupancy detection solutions focus on residential environments. Confined metallic spaces such in industrial environments are...

Securing Deep Spiking Neural Networks against Adversarial Attacks through Inherent Structural Parameters

R. El-Allami, A. Marchisio, M. Shafique, Ihsen Alouani

Deep Learning (DL) algorithms have gained popularity owing to their practical problem-solving capacity. However, they suffer from a serious integrity threat, i.e., their vulnerability to adversarial attacks. In the quest for DL trustworthiness, recent works claimed the inherent robustness of...

High-Q silicon nitride drum resonators strongly coupled to gates

Xin Zhou, Srisaran Venkatachalam, Ronghua Zhou, Hao Xu, Alok Pokharel, Andrew Fefferman, Mohammed Zaknoune, Eddy Collin

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an electrical circuit for efficient on-chip integration...

Modeling and experimental analysis of the mass loading effect on micro-ionic polymer actuators using step response identification

Iman Dadras, Sofiane Ghenna, Sébastien Grondel, Eric Cattan, Jaan Raik, Alvo Aabloo, Saoni Banerji

This paper presents a linear electrochemomechanical model for microscale ionic actuators. A frequency-domain approach is used to facilitate model interpretation, simplify model application, and accelerate the generation of actuator-specific models. A system comprising a micro PEDOT:PSS/PEO actuator...

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine...

Bias-dependence of surface charge at low temperature in GaN self-switching diodes

E. Perez-Martin, I. Iniguez-De-La-Torre, T. Gonzalez, Christophe Gaquière, J. Mateos

In this work, with the help of a semi-classical two-dimensional Monte Carlo (MC) simulator, we study the DC current-voltage curves of Self-Switching Diodes (SSDs) fabricated on an AlGaN/GaN heterostructure from 100 K up to room temperature. Due to the very narrow channel of the SSDs, the presence...

Bowl-shaped ZnO ultrasonic transducer for photoacoustic/ultrasonic multimode microscopy

J. Zhang, D. Zhao, D. Li, F. Tian, Wei-Jiang Xu, X. Wu

A bowl-shaped ultrasonic transducer is proposed for photoacoustic/ultrasonic multimode microscopy. The transducer uses zinc oxide (ZnO) as the piezoelectric material, which has a better electromechanical coefficient than flexible PVDF polymer and ensures the detection sensitivity. The ZnO film is...

Thermoacoustic wave generation in multilayered thermophones with cylindrical and spherical geometries

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat

A thermoacoustic sound generation model, based on the classical balance equations of the continuum mechanics, is here developed for the cylindrical and the spherical thermoacoustic wave generation. In both geometries, the model considers an arbitrary multilayered structure, where each layer can be...

A generalized deep learning-based framework for assistance to the human malaria diagnosis from microscopic images

Ziheng Yang, Halim Benhabiles, Karim Hammoudi, Feryal Windal, Ruiwen He, Dominique Collard

Malaria is an infectious disease caused by Plasmodium parasites and is potentially human life-threatening. Children under 5 years old are the most vulnerable group with approximately one death every two minutes, accounting for more than 65% of all malaria deaths. The World Health Organization (WHO...
