The next generation of soft robotics, smart clothing and biocompatible medical devices are going to need integrated soft sensors that can stretch and twist with the device or wearer. The challenge: most of the components used in traditional sensing are rigid. Now, researchers have developed a soft, self-powered thermometer that can be integrated into stretchable electronics and soft robots.
Researchers have successfully demonstrated proof-of-concept of using their multimodal transistor (MMT) in artificial neural networks, which mimic the human brain. This is an important step towards using thin-film transistors as artificial intelligence hardware and moves edge computing forward, with the prospect of reducing power needs and improving efficiency, rather than relying solely on computer chips.
For electric vehicles (EVs) to become mainstream, they need cost-effective, safer, longer-lasting batteries that won't explode during use or harm the environment. Researchers may have found a promising alternative to conventional lithium-ion batteries made from a common material: rubber.
Researchers 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 expensive microfabrication facilities.
A pioneering type of patented computer memory known as ULTRARAM™ has been demonstrated on silicon wafers in what is a major step towards its large-scale manufacture. ULTRARAM™ is novel type of memory with extraordinary properties. It combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency and endurance of a working memory, like DRAM. To do this it utilizes the unique properties of compound semiconductors, commonly used in photonic devices such as LEDS, laser diodes and infrared detectors, but not in digital electronics, which is the preserve of silicon.
A team sees stripes in samples of twisted double bilayer graphene, indicating the presence of a nematic phase characterized by broken rotational symmetry.
Researchers have designed and simulated the first topological acoustic transistors -- with sound waves instead of electrons -- and proposed a connection architecture to form a universal logic gate that can switch the flow of sound on and off.
Researchers discuss the properties of silk and recent and future applications of the material. It has been used in drug delivery and is ideal for wearable and implantable health monitoring sensors. Silk is also useful in optics and electronics and more recently has come to the forefront of sustainability research. The use of silk coatings may also reduce food waste, which is a significant component of the global carbon footprint.
Researchers have discovered that the junctures at the facet edges of 3D semiconductor particles have 2D properties, which can be leveraged for photoelectrochemical processes -- in which light is used to drive chemical reactions -- that can boost solar energy conversion technologies.
Researchers have used a unique tool inserted into an electron microscope to create a transistor that's 25,000 times smaller than the width of a human hair.
Researchers have developed a technique to improve the flexibility of ultra-thin electronics, such as those used in bendable devices or clothing. To do so, they used water-vapor plasma to directly bond gold electrodes fixed onto separate ultra-thin polymer films. This is a significance advance because the technique works without adhesives or high temperatures.
Quantum effects in superconductors could give semiconductor technology a new twist. Researchers have identified a composite material that could integrate quantum devices into semiconductor technology, making electronic components significantly more powerful.
Bioactive coatings play a vital role in the success of implants such as those for knees or hips, because their properties induce a biological response that is good for the health. Researchers are working on a coating that mimics bone tissue.
Scientists have shown how electricity is transported in printed 2D materials, paving the way for design of flexible devices for healthcare and beyond.
Researchers review scientific advances of electrolyte-gated carbon nanotube field-effect transistor biosensors, which are characterized by superior electronic properties and intrinsic signal amplification and are capable of detecting a wide range of biomolecules with high sensitivity. One of their main components is the biorecognition element, which selectively recognizes the analyte of interest. Biotransduction devices convert the interaction between the biorecognition element and analyte into a measurable signal.
Researchers have observed interfacial phonon modes which only exist at the interface between silicon (Si) and germanium (Ge). This discovery shows experimentally that decades-old conventional theories for interfacial heat transfer are not complete and the inclusion of these phonon modes are warranted.
Researchers have developed a rechargeable lithium-ion battery in the form of ultra-long fiber that could be woven into fabrics. The battery could enable a wide variety of wearable electronic devices, and might even be used to make 3D-printed batteries in virtually any shape.
To overcome the slow charging times of conventional lithium-ion batteries, scientists have developed a new anode material that allows for ultrafast charging. Produced via a simple, environmentally sound and efficient approach involving the calcination of a bio-based polymer, this novel material also retained most of its initial capacity over thousands of cycles. The findings of this study will pave the way to fast-charging and durable batteries for electric vehicles.
Researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency.
Intelligent packaging with sensors that monitor goods, such as vegetables, on long transport routes is a trend for the future. Yet printed and disposable electronics also cause problems: Metals in printing inks are expensive -- and disposing of them in an environmentally sound manner is costly and exacerbates the problem of electronic waste.
