Electronic

Scientists experimenting with novel materials have made a breakthrough that could shape a new generation of electronic devices, combining two characteristics in a way they say defies a theoretical explanation.

We’ve all been annoyed by someone taking a loud call in a quiet room, and now a Japanese tech company has unveiled a creative, if somewhat bizarre, solution. The Mutalk is a Bluetooth mouthpiece that “mutes” users who speak into it.

Why design robots from scratch when nature has already done the hard work for us? That’s the reasoning behind cyborg insects, and now scientists have found a way to power remote-controlled cyborg cockroaches using custom solar cells.

Discarded electronics can be a gold mine – literally. Researchers have developed an efficient new way to use graphene to recover gold from electronic waste, without needing any other chemicals or energy.

MIT engineers have developed a new type of artificial synapse that’s extremely energy efficient and ultra-fast, processing data a million times faster than synapses in the human brain. The analog device shuttles protons around instead of electrons.

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound waves.

Scientists have developed a new electronic “tattoo” that can monitor a patient’s blood pressure continuously. The e-tattoo is made of graphene and can be worn for long periods without getting in the way, allowing for better health data.

A team from the University of Illinois and UC Berkeley has demonstrated a new cooling method that sucks heat out of electronics so efficiently that it allows designers to run 7.4 times more power through a given volume than conventional heat sinks.

Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips.

Smart textiles are usually fairly limited in size and scope. Now a team of scientists has woven together a 46-inch textile display, loaded with LEDs, sensors and energy storage, which can be made using existing industrial manufacturing processes.

Indium is one of the rarest metals on Earth, but it’s a key ingredient in ubiquitous electronic devices. Engineers have demonstrated a way to swap indium for graphene, which is made from common carbon, while retaining the same electronic properties.

Superconductivity occurs when electrons in a metal pair up. Scientists in Germany have now discovered that electrons can also group together into families of four, creating a new state of matter and potentially a new type of superconductivity.
