Amit Nagarkar helped develop a data-storage system that uses fluorescent dyes. Credit: Kris Snibbe/Harvard Staff In the digital age, every byte of data needs to go somewhere—and preferably stay there a long time. That last part is a major problem when it comes to data-storage systems, which typically last less...

The development overcomes one of the most significant advantages e-books have over paper books, helping paper maintain its strong position in its competition with electronic media.   Researchers at the University of...

The electrical characteristic model is composed of multiple nonlinear equations. In order to apply AD, this is represented by a directed acyclic graph. Each vertex represents an arithmetic operation such as four arithmetic operations, logarithms, and exponents, and each node represents intermediate variables. Optimizing model parameters to minimize the difference...

The working principle of the device. Credit: Wang et al. Semiconductor p-n junctions are boundaries between two types of semiconductors (i.e., p-type and n-type semiconductor materials). These junctions are crucial components of many modern electronic devices. So far, typical p-n junction-based devices have only allowed current to flow in one...

University of Arizona engineers have developed a way to 3D-print medical-grade wearable devices, such as this one, based on body scans of the wearer. Credit: Gutruf Lab / University of Arizona Wearable sensors to monitor everything from step count to heart rate are nearly ubiquitous. But for scenarios such as...

A Cornell-led collaboration created a system that uses combustion to inflate silicone membrane “dots,” which could someday serve as a dynamic braille display for electronics. The stretchable technology could also be incorporated into soft robots, surgical tools and wearable virtual reality equipment. Credit: Cornell University Imagine an iPad or a...

The feat, which lead researcher Rafael Jaramillo refers to as his...

UCLA-designed self-powered, stretchable, waterproof magnetoelastic generator for bioelectronics. Credit: Jun Chen/UCLA A team of bioengineers at the UCLA Samueli School of Engineering has invented a novel soft and flexible self-powered bioelectronic device. The technology converts human body motions—from bending an elbow to subtle movements such as a pulse on one's...

Figure 1. Fabrication of 3D foldable QLEDs that can be folded freely as paper. The ultra-thin QLED can be sharply folded along the laser-etched line, just like the origami paper artwork. A three-dimensional foldable QLED with various user-customized shapes such as airplanes, butterflies, and pyramids was fabricated. The 3D foldable...
