Researchers have developed floating 'artificial leaves' that generate clean fuels from sunlight and water, and could eventually operate on a large scale at sea. The researchers designed ultra-thin, flexible devices, which take their inspiration from photosynthesis - the process by which plants convert sunlight into food. Since the low-cost, autonomous devices are light enough to float, they could be used to generate a sustainable alternative to petrol without taking up space on land.

This premium article will look into the manufacturing and materials involved in electronic skin patches, including an overview of skin patch construction, opportunities for roll-to-roll (R2R) manufacturing, case studies of contract manufacturers producing electronic skin patches, and more.

Organic solar cells, which make use of organic materials to convert sunlight into electricity, are an attractive candidate for future photovoltaics. This is due to several of their desirable features, such as their light weight, flexibility, malleability, and, most importantly, high power conversion efficiency . Such qualities make them ideal for a wide range of applications.

Researchers say they have created the first gel-based cartilage substitute that is even stronger and more durable than the real thing. Mechanical testing reveals that the team's hydrogel -- a material made of water-absorbing polymers -- can be pressed and pulled with more force than natural cartilage, and is three times more resistant to wear and tear.

Solar panels aren't just for rooftops anymore - some buildings even have these power-generating structures all over their facades. But as more buildings and public spaces incorporate photovoltaic technologies, their monotonous black color could leave onlookers underwhelmed. Now, researchers have created solar panels that take on colorful hues while producing energy nearly as efficiently as traditional ones.

This premium article introduces metamaterials, with examples and important applications, and explores the commercial metamaterial ecosystem, technical and commercial challenges, and more.

hofer powertrain opts for the most future-proof chip technologies and develops new multilevel power electronics with VisIC Technologies' Gallium Nitride chip technology, D3GaN (Direct Drive D-Mode), capable of meeting the needs of modern drivetrains and breaking efficiency barriers.

The recently-unveiled 97-inch OLED.EX display boasts the company's special Cinematic Sound OLED technology, which allows the display to vibrate and generate the sound directly from the display without separate speakers. A 5.1 channel sound system is embedded into the widescreen, creating a performance that offers a cinematic level of immersion.

Wearable human-machine interface devices can be used to control machines, computers, music players, and other systems. A challenge for conventional human-machine interfaces is the presence of sweat on human skin. Scientists now describe their development of a type of human-machine interface that is stretchable, inexpensive, and waterproof. The device is based on a soft magnetoelastic sensor array that converts mechanical pressure from the press of a finger into an electrical signal.

Computers that think more like human brains are inching closer to mainstream adoption. But many unanswered questions remain. Among the most pressing, what types of materials can serve as the best building blocks to unlock the potential of this new style of computing.
