Output Capacitance Losses in Wide-Band-Gap Transistors: A Small-Signal Modeling Approach

Elison de Nazareth Matioli, Armin Jafari, Palliyage Srilak Nirmana Perera

Wide-band-gap (WBG) power semiconductor devices are gaining an increasing interest in power circuits, as they exhibit a low specific ON-resistance (RON) while providing a high blocking voltage. The energy dissipation corresponding to resonantly charging an ...

SPICE Modeling of Photoelectric Effects in Silicon With Generalized Devices

Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella, Chiara Rossi

Modeling photoelectric effects in semiconductors with electrical simulators is demonstrated in typical 1-D and 2-D architectures. The concept is based on a coarse meshing of the semiconductor with the so-called generalized lumped devices, where equivalent ...

All‐Fabric Wearable Electroadhesive Clutch

Dario Floreano, Vivek Ramachandran, Jun Shintake

A lightweight, textile fabricated, haptic device consisting of an electrostatic adhesive clutch is introduced, which can constrain body movement when activated at low power (≈1 mW). The clutch electrodes are composite structures, prepared by coating copper ...

Battery Storage System Optimal Exploitation Through Physics-Based Model Predictive Control

Mario Paolone, Fabrizio Sossan, Dimitri Torregrossa, Emil Namor

Traditionally, the safe operation of a battery energy storage system (BESS) is achieved by imposing conservative constraints on its DC bus current and voltage. By using a computationally efficient single particle model (SPM), we propose to replace these co ...

A Fully Integrated Counter Flow Energy Reservoir for Peak Power Delivery in Small Form-Factor Sensor Systems

Kyojin Choo, Yao Shi

We present a fully integrated energy reservoir unit using a counter flow method for peak power delivery in space-constrained sensor systems. Recent advances in circuits have enabled significant reduction in the size of wireless systems such as implantable ...

22.6 A fully integrated counter-flow energy reservoir for 70%-efficient peak-power delivery in ultra-low-power systems

Kyojin Choo, Yao Shi

Recent advances in circuits have enabled significant reduction in the size of wireless systems such as implantable biomedical devices. As a consequence, the battery integrated in these systems has also shrunk, resulting in high internal resistances (~10kΩ) ...

Macroscopic indicators of fault diagnosis and ageing in electrochemical double layer capacitors

Hubert Girault, Mario Paolone, Dimitri Torregrossa, Véronique Amstutz, Kathryn Ellen Toghill

The ageing behaviour of electric double layer (EDLC) supercapacitors during over-temperature and over-voltage stresses is described. Specific experimental tests were carried out in order to reproduce, under laboratory controlled conditions, the above-menti ...

Hydrogen dynamics in the low temperature phase of LiBH4 probed by quasielastic neutron scattering

LiBH4 contains 18.5 wt% hydrogen and undergoes a structural phase transition (orthorhombic → hexagonal) at 381 K which is associated with a large increase in hydrogen and lithium solid-state mobility. We investigated the hydrogen dynamics in the low temper ...

Nanocomposite of MoS2 on ordered mesoporous carbon nanospheres: A highly active catalyst for electrochemical hydrogen evolution

Hubert Girault, Micheal Diarmaid Scanlon, Peiyu Ge, Jie Zhu

An efficient electrocatalyst for hydrogen evolution has been developed based upon in situ reduction of MoS2 on ordered mesoporous carbon nanospheres (MoS2/MCNs). The properties of MoS2/MCNs were characterised by scanning electron microscopy, transmission e ...

Enhancement of actuation ability of ionic-type conducting polymer actuators using metal ion implantation

Herbert Shea

In this study, we present the results and implications of an experimental study into the effect of gold-ion implantation on the actuation performance of ionic-type conducting polymer actuators, represented here by cantilevered tri-layer polypyrrole (PPy) a ...
