Researchers at the Indian Institute of Science (IISc) have developed a fully indigenous gallium nitride (GaN) power switch that can have potential applications in systems like power converters for electric vehicles and laptops, as well as in wireless communications. The entire process of building the switch—from material growth to device fabrication to packaging—was developed in-house … Read more
Epicardial patches are carefully engineered tissue patches that can be placed near or on a patient’s heart. These devices can help doctors to diagnose and treat a variety of heart conditions, including arrhythmia and heart attacks (i.e., myocardial infarctions). In recent years, several engineers and medical researchers have been trying to develop these devices, yet … Read more
The semiconductor industry today is working to respond to a threefold mandate: increasing computing power, decreasing chip sizes and managing power in densely packed circuits. To meet these demands, the industry must look beyond silicon to produce devices appropriate for the growing role of computing. While unlikely to abandon the workhorse material anytime in the … Read more
A team of mechanical engineers at Nanyang Technological University in Singapore has found a way to electronically control cockroaches without injuring them. In their paper published in the journal npj Flexible Electronics, the group describes the new technology they used to remotely control the cockroaches and the benefits of doing so. Prior research teams have … Read more
Devices that can detect, track and decode movements in their surroundings can have countless valuable applications in fields ranging from robotics to health care, the entertainment industry, sports, and more. Wearable sensors can be particularly effective in detecting and recording the movements of human users, as they can be strategically placed and may pick up … Read more
Using a biosensor to detect cystic fibrosis as the test case, TU/e researchers have devised an innovative way to train neuromorphic chips as presented in a new paper in Nature Electronics. Neuromorphic computers—which are based on the structure of the human brain—could revolutionize our future health care devices. However, their widespread use is hindered by … Read more
We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers at EPFL have revealed a pioneering technology that combines the … Read more
A team of researchers, led by Professor Ji-Hyun Jang from the School of Energy and Chemical Engineering at UNIST has achieved a significant breakthrough in photoelectrode development. Through collaborative research with Professor Junghoon Lee from Dongseo University and Dr. Hyo-Jin Ahn from the German Engineering Research and Development Center LSTME Busan, the team successfully created … Read more
Silicon heterojunction (SHJ), solar cells based on a heterojunction between semiconductors with different band gaps, are among the most promising photovoltaic technologies. So far, these cells have exhibited remarkable power conversion efficiencies and good operational stabilities. Despite their great potential and notable advantages, SHJ solar cells are typically based on rare and expensive materials, which … Read more
With the rapid growth of the smart and wearable electronic devices market, smart next-generation energy storage systems that have energy storage functions as well as additional color-changing properties are receiving a great deal of attention. However, existing electrochromic devices have low electrical conductivity, leading to low efficiency in electron and ion mobility, and low storage … Read more
