The researchers — who are based at IBM Research — fabricated a 14-nm inference chip containing 34 tiles, each of which contains a crossbar array of phase-change memory devices that can perform matrix–vector multiplications. Overall, the chip has 35 million phase-change memory devices. The chip also contains digital-to-analogue input, analogue-to-digital output, analogue peripheral circuitry and parallel-2D-mesh

With advances in capabilities coming hand in hand with calls for regulation, 2023 is proving to be a critical year for brain–computer interfaces.

The researchers — who are based at Delft University of Technology, QuTech and the Netherlands Organisation for Applied Scientific Research — created their crossbar architecture using strained germanium quantum wells with double-barrier gates and a diagonal plunger line layout. This approach allows a single gate to control multiple quantum dots with a sublinear number of control terminals, thus reducing

As I write this column, the yearly metrics that measure the impact of scientific journals have just been released, and this year, the results somehow stand in contrast for our magazine: its impact factor (IF) dropped two points, to 6.3 (Clarivate), while its CiteScore grew 2.4 points, to 12 (Scopus). To better understand why the IF dropped this year, first, we must remember that an IF is a ratio: the

Dear IEEE Industrial Electronics Society (IES) members,

Power grids are undergoing an epoch-making evolution since many countries, notably those in the European Union, aim at decarbonizing energy in the next decades, namely phasing-out fossil fuel sources and replacing them with renewable energy sources (RESs), in the framework of climate change mitigation and strategic sources independence from importation. Among RESs, hydropower remains the most diffuse

Any modern storage system requires a management unit, which is made up of hardware and software components, to control charge and discharge phases; to ensure the optimal operating conditions, which must be kept within a safe operating area; to monitor system parameters; to quantify its state of charge (SoC) and state of health (SoH); and to communicate with other systems and with the user. All these

The researchers — who are based at the National Institute for Materials Science, Mie University, Keio University, Osaka University and TDK Corporation — studied 252 combinations of different magnesium (Mg2+) and gallium (Ga3+) cation occupations in the spinel material. The simulations were performed using a machine-learning factorization machine developed by the team in combination with D-Wave’s Advantage

Training Spiking Neural Networks Using Lessons From Deep Learning by J. K. Eshraghian, M. Ward, E. O. Neftci, X. Wang, G. Lenz, G. Dwivedi, M. Bennamoun, D. S. Jeong, and W. D. Lu

Motivated by the advancing computational capacity of distributed end-user equipment (UE), as well as the increasing concerns about sharing private data, there has been considerable recent interest in machine learning (ML) and artificial intelligence (AI) that can be processed on distributed UEs. Specifically, in this paradigm, parts of an ML process are outsourced to multiple distributed UEs. Then

With great pleasure, we would like to present the Special Section on Multilevel Converters as an Enabler for Grid Modernization of the IEEE Transactions on Power Electronics (TPEL), which focuses on the research and development of multilevel converters in modern power grids. On the one hand, we investigate the implementation of grid-supportive services and novel control schemes provided by multilevel

Wireless power transfer (WPT) technology has become a developing trend with the advantages of flexibility and security. However, WPT systems also face some challenges, such as output power fluctuations caused by misalignment or dynamic charging, accurate modeling of high-order systems, system integration, load estimation, and simultaneous transmission of power and data. Therefore, advanced topologies

Switched capacitor converters (SCCs) have been widely investigated and used in both academia and industry for many years, ranging from low power (milliwatt level) to high power (several kilowatt levels) for a myriad of applications. SCCs offer several advantages, including the elimination of inductor and related magnetic design issues and hence low electromagnetic interference (EMI), better form factor

The brain is the perfect place to look for inspiration to develop more efficient neural networks. The inner workings of our synapses and neurons provide a glimpse at what the future of deep learning might look like. This article serves as a tutorial and perspective showing how to apply the lessons learned from several decades of research in deep learning, gradient descent, backpropagation, and neuroscience

With the increasing penetration of renewable energy and flexible loads in smart grids, a more complicated power system with high uncertainty is gradually formed, which brings about great challenges to smart grid operations. Traditional optimization methods usually require accurate mathematical models and parameters and cannot deal well with the growing complexity and uncertainty. Fortunately, the widespread

The electronics are first fabricated on a planar substrate and then picked up by the petal-like stamp, which consists of a silicone rubber and water-soluble double-sided adhesive tape. Key to the transfer process is controlling the wrapping process so the stamp applies a uniform pressure at all points on the target curvy surface. This is achieved by placing the target and stamp in a pre-strained wrapping

The researchers — who are based at Linköping University, the International School for Advanced Studies, Columbia University, the University of Milan and the Swedish University of Agricultural Sciences — developed a 20 mm × 25 mm grid containing 120 polymer-based electrodes. They found that the action potentials in the lobes of the Venus flytrap when a trigger hair is stimulated propagate at constant

The researchers — who are based at Yonsei University, Hongik University, Kongju National University and the Institute for Basic Science in Korea — developed a hot-wall metal–organic chemical vapour deposition method to grow MoS2 on flexible substrates attached to a rigid carrier substrate, which can later be removed. The growth process also leads to larger domain sizes across the MoS2 films compared

Each cellular unit has a hydraulically amplified self-healing electrostatic actuator, a sensor combining a soft magnetic block and magnetometer, and a driving circuit with a high-voltage sensor to regulate the actuator voltage. The cells, which are 60 mm × 60 mm in size, can exhibit reversible shape morphing at a rate of up to 50 Hz. The magnetic-based sensors embedded in the surface layer are interference-free
