Triboelectric‐TFT Flip‐Flop for Bistable Latching of Dielectric Elastomer Actuators

Danick Briand, Herbert Shea, Rubaiyet Iftekharul Haque, Alexis Pierre Henri Marette, Xiaobin Ji, Ronan Julien Hinchet

A high‐voltage flip‐flop combining two self‐powered soft sensors with a flexible high‐voltage thin film transistor (HVTFT) is reported, and is used to electrically latch dielectric elastomer actuators (DEAs) in zero and high‐strain states. Two touch‐actuat ...

Façade design and our experience of space: the joint impact of architecture and daylight on human perception and physiological responses

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

Daylight has an undeniable value in various aspects of architectural design, ranging from energy efficiency and user comfort to our experience of space. Even though there is substantial evidence of the positive effects of daylight access on occupants, we h ...

A Pipelined Speed Enhancement Technique for CDAC-Threshold Configuring SAR ADC

Mustafa Kilic, Yusuf Leblebici

In this paper, a novel SAR ADC architecture enabling very high speed operation is presented. Based on a hybrid capacitive DAC-threshold configuring scheme, the proposed architecture performs conversions in two-stages, similarly to pipelined ADCs. An additi ...

From Timed Component-Based Systems to Time-Triggered Implementations: A Correct-by-Design Approach

In hard real-time embedded systems, design and specification methods and their associated tools must allow development of temporally deterministic systems to ensure their safety. To achieve this goal, we are specifically interested in methodologies based o ...

Inverted Current-Voltage Hysteresis in Mixed Perovskite Solar Cells: Polarization, Energy Barriers, and Defect Recombination

Michael Graetzel, Wolfgang Richard Tress, Michael Saliba, Antonio Abate

Organic-inorganic metal halide perovskite solar cells show hysteresis in their current-voltage curve measured at a certain voltage sweep rate. Coinciding with a slow transient current response, the hysteresis is attributed to a slow voltage-driven (ionic) ...

Correct Transformation of High-Level Models into Time-Triggered Implementations

Simon Bliudze

A number of component-based frameworks have been proposed to tackle the complexity of the design of concurrent software and systems and, in particular, to allow modelling and simulation of critical embedded applications. Such design frameworks usually prov ...

Influence of ground wire on the initiation of upward leader from 110 to 1000kV AC phase line

Xi Wang, Rong Zeng

The problem of upward leader inception from transmission lines has not been thoroughly discussed, largely because of the difficulty to obtain experimental data under natural circumstances. Previous studies have primarily examined reduced-scale experiments ...

Multiple-Independent-Gate Field-Effect Transistors for High Computational Density and Low Power Consumption

Jian Zhang

Transistors are the fundamental elements in Integrated Circuits (IC). The development of transistors significantly improves the circuit performance. Numerous technology innovations have been adopted to maintain the continuous scaling down of transistors. W ...

Spatial multistability induced by cross interactions of confined polariton modes

Benoît Marie Joseph Deveaud, Daniel Oberli, François Morier-Genoud, Marcia Portella Oberli, Claudéric Ouellet-Plamondon, Grégory Chilpéric Sallen

We demonstrate the occurrence of spatial multistability using laterally confined microcavity exciton-polaritons. By coherently exciting with a blue detuned laser a series of confined polariton modes, we investigate the effects of multistability on the tran ...
