Optimization of surface treatment on MEMS probes for single-cell capture and release

Kensaku Hayashi, Momoko Kumemura, Shohei Kaneda, Vivek Menon, Laurent Jalabert, Saeko Tachikawa, Mehmet Tarhan, Teruo Fujii, Beomjoon Kim, Hiroyuki Fujita

Micro-electromechanical systems (MEMS) tweezers developed for the trapping and characterization of bio molecules such as DNA are also capable of cell handling, which will enable further application involving single cell characterization. However, cellular adhesion to Si tweezers surfaces can…

Topological valley, pseudospin, and pseudospin-valley protected edge states in symmetric pillared phononic crystals

Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present a symmetric double-sided pillared phononic crystal (PPnC) where either quantum spin Hall effect (QSHE) or quantum valley Hall effect (QVHE) is emulated by solely imposing different perturbations to the geometry. When occurring at the deep subwavelength scale, the valley-polarized edge…

Mesure indirecte des performances de LLR approché

Yasser Mestrah, Anne Savard, Alban Goupil, Guillaume Gelle, Laurent Clavier

Les réseaux sans fils sont de plus en plus denses et hétérogènes, entraînant l’accroissement très significatif de l’impact des interférences. De nombreux travaux ont montré la nature impulsive de cette interférence et la nécessité de modifier le calcul de la vraisemblance nécessaire au décodage.…

An autonomous low-power management system for energy harvesting from a miniaturized spherical piezoelectric transducer

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Samih Isber, Fawaz El Omar, Adnan Naja

A new spherical vibrational energy harvesting device with an additional low power management circuit for optimizing the power transfer from the mechanical vibrations to a storage capacitor is presented. The device is devoted to underwater wireless sensor network applications due to its broadband…

Towards all-solution-processed top-illuminated flexible organic solar cells using ultrathin Ag-modified graphite-coated poly(ethylene terephthalate) substrates

Shuanglong Wang, Yi Zhao, Hong Lian, Cuiyun Peng, Xuyong Yang, Yulai Gao, Yan Peng, Weixia Lan, Omar Ibrahim Elmi, Didier Stiévenard, Bin Wei, Furong Zhu, Tao Xu

All-solution-processed flexible organic solar cells (FOSCs) with high power conversion efficiency (PCE) are the prerequisite for application in low-cost, large-area, flexible, photovoltaic devices. In this work, high-performance, top-illuminated FOSCs using ultrathin Ag-modified graphite-coated…

On the impact of the covariance matrix size for spectrum sensing methods:beamforming versus eigenvalues

Kais Bouallegue, Matthieu Crussière, Iyad Dayoub

In this paper, we investigate the impact of the covariance matrix (CM) size of the received signal on the performance of spectrum sensing methods. Our analysis is based on two well-known methods of spectrum sensing (SS), one based on the eigenvalues called maximum-to minimum eigenvalue (MME) and…
