3D printing leads to fabricating a shape memory alloy with increased superelasticity

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although this manufacturing technique is attractive for applications in the biomedical and aerospace fields, it has rarely showcased the superelasticity required for specific applications using nickel-titanium shape memory alloys. Defects generated and Read more about 3D printing leads to fabricating a shape memory alloy with increased superelasticity[…]

Intelligent metasurface as an emerging research direction involving various disciplines

The manipulation of electromagnetic waves and information has become central to our daily lives. Intelligent metasurfaces have emerged as smart platforms for controlling the wave-information-matter interactions without manual intervention. They evolved from engineered composite materials, including metamaterials and metasurfaces. As a society, we have witnessed significant progress of metamaterials and metasurfaces with different forms and Read more about Intelligent metasurface as an emerging research direction involving various disciplines[…]

Paradigm shift urgently needed for forecasting corrosion within civil engineering structures

The most common cause of degradation and failures of reinforced concrete structures is chloride-induced corrosion of its embedded steel. This is a pervasive, urgent problem that requires immediate attention and public awareness. An underlying concept of a chloride threshold is widely used, and all existing models to forecast corrosion performance of reinforced concrete structures exposed Read more about Paradigm shift urgently needed for forecasting corrosion within civil engineering structures[…]

Increasing efficiency in the manufacturing industry using machine learning assistance

Efficiency rates for production machinery frequently fall far below what technology could achieve. The common reason is experienced employees are not always available when a failure occurs while other employees lack the experience to solve the actual cause. That is where MADDOX comes in. A smart and self-learning assistance system that uses machine learning methods Read more about Increasing efficiency in the manufacturing industry using machine learning assistance[…]

Brain-based computing chips not just for AI anymore

With the insertion of a little math, Sandia National Laboratories researchers have shown that neuromorphic computers, which synthetically replicate the brain’s logic, can solve more complex problems than those posed by artificial intelligence and may even earn a place in high-performance computing. A random walk diffusion model based on data from Sandia National Laboratories algorithms Read more about Brain-based computing chips not just for AI anymore[…]

Haptic fingertip sensitivity for robots

In a paper published on February 23, 2022 in Nature Machine Intelligence, a team of scientists at the Max Planck Institute for Intelligent Systems (MPI-IS) introduce a robust soft haptic sensor named “Insight” that uses computer vision and a deep neural network to accurately estimate where objects come into contact with the sensor and how large the applied Read more about Haptic fingertip sensitivity for robots[…]

Haptic feedback for custom fabricated multichannel bimodal soft robotic armband

Typing on a keyboard, pressing buttons on a remote control or braiding a child’s hair has remained elusive for prosthetic hand users. With current myoelectric prosthetic hands, users can only control one grasp function at a time even though modern artificial hands are mechanically capable of individual control of all five digits. A first-of-its-kind study Read more about Haptic feedback for custom fabricated multichannel bimodal soft robotic armband[…]

Using quantum physics to generate electricity

Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology would be ideally suited for low-power electronics applications such as wearables or low-cost Internet-of-Things devices. This includes, for Read more about Using quantum physics to generate electricity[…]

Technology opens door to ubiquitous, more easily fabricated electronic screens

In a groundbreaking new study, researchers at the University of Minnesota Twin Cities used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display. The discovery could result in low-cost OLED displays in the future that could be widely produced using 3D printers by anyone at home, instead of by technicians in Read more about Technology opens door to ubiquitous, more easily fabricated electronic screens[…]

Traffic jam analyzed by AI

How much does a country’s vehicle fleet consume on average? How does it change from year to year? With the increasing number of electric vehicles and more and more “crossover” models that can hardly be assigned to one vehicle segment, analysis is becoming increasingly difficult. Empa researchers analyze databases using deep learning methods – and Read more about Traffic jam analyzed by AI[…]

New microspeakers brings Alexa in your ear

The microspeakers for wireless in-ear headphones from Arioso Systems GmbH, a spin-off of the Fraunhofer Institute for Photonic Microsystems IPMS, are up to ten times smaller than conventional microspeakers and are made entirely from silicon. Currently at the prototype stage, the energy-efficient MEMS speakers may in future play a role in expanding the range of Read more about New microspeakers brings Alexa in your ear[…]

Cryobioprinting can give bioprinted tissue an extended shelf life

A new technique takes bioprinting — in which an ink of cells is printed, layer by layer, to form a structure — to a whole new, and icy level. Investigators from the Zhang lab at Brigham and Women’s Hospital have developed a technology that they term “cryobioprinting,” a method that uses a bioink embedded with Read more about Cryobioprinting can give bioprinted tissue an extended shelf life[…]
