Ahmad Itawi, Sofiane Ghenna, Guillaume Tourrel, Sébastien Grondel, Cedric Plesse, Giao Tran Minh Nguyen, Frederic Vidal, Yinoussa Adagolodjo, Lingxiao Xun, Gang Zheng, Alexandre Kruszewski, Christian Duriez, Eric Cattan

Cochlear implants made of standard silicone electrode array (EA) are currently used to stimulate the auditory nerve of patients’ cochlea. The implants have a proximal diameter of 0.5mm and 2~3cm long composed of 20 bulk platinum electrodes and connection wires (Ø 25µm). Due to their stiffness and...

Preparation of photothermal nanomaterials for water treatment, Préparation de nanomatériaux photothermiques pour la purification d'eau

Go Inoue

Solar interfacial evaporation has recently emerged as a solution to alleviate the water shortage of our century in an environmentally-friendly way. However, the low efficiency of water-steam conversion, the high cost for the preparation of the evaporator, and the scarcity of raw materials are major..., L'évaporation interfaciale solaire est apparue récemment comme une solution pour pallier la pénurie d'eau de notre siècle de manière écologique. Cependant, la faible efficacité de la conversion eau-vapeur, le coût élevé de la préparation de l'évaporateur et la rareté des matières...

Space-time Modulation in a Piezoelectric Phononic Crystal: Experimental Study in Sub-sonic and Sonic Regimes

Sarah Tessier Brothelande, Charles Croenne, Florian Allein, Jerome Vasseur, Bertrand Dubus

We experimentally study acoustic wave propagation in a spatio-temporally modulated system for different modulation speeds, up to the sonic regime when the modulation speed is similar to the wave propagation speed. The system under study is a piezoelectric phononic crystal whose electrical boundary...

Signal Denoising and Detection for Uplink in LoRa Networks based on Bayesian-optimized Deep Neural Networks

Angesom Ataklity Tesfay, Sofiane Kharbech, Eric Pierre Simon, Laurent Clavier

Long-range and low-power communications are suitable technologies for the Internet of things networks. The long-range implies a very low signal-to-noise ratio at the receiver. In addition, low power consumption requires reduced signaling, hence the use of less complex protocols, such as ALOHA, so...
