A team of Japanese researchers from Waseda University, Osaka University, and Shizuoka University designed and successfully developed a high-power, silicon-nanowire thermoelectric generator which, at a thermal difference of only 5 degrees C, could drive various IoT devices autonomously in the near future.

Objects in our daily lives, such as speakers, refrigerators, and even cars, are becoming “smarter” day by day as they connect to the internet and exchange data, creating the Internet of Things (IoT), a network among the objects themselves. Toward an IoT-based society, a miniaturized thermoelectric generator is anticipated to charge these objects, especially for those that are portable and wearable.

Due to advantages such as its relatively low thermal conductance but high electric conductance, silicon nanowires have emerged as a promising thermoelectric material. Silicon-based thermoelectric generators conventionally employed long, silicon nanowires of about 10–100 nanometers, which were suspended on a cavity to cutoff the bypass of the heat current and secure the temperature difference across the silicon nanowires. However, the cavity structure weakened the mechanical strength of the devices and increased the fabrication cost.

The Bcon wearable gaming controller can be worn on your head or foot.

MyDefence is launching PITBULL – a next generation wearable Counter UAS solution utilizing smart jamming to defeat enemy drones. PITBULL is developed to have minimal impact on other signals while jamming, in an effort to maintain own communication. The Counter UAS jammer weighs 775 grams and can be worn on the uniform.

DigiLens, a developer of transparent waveguide display technology, says it’s working toward a waveguide display which could bring a 150 degree field of view to AR and VR (or XR) headsets. The company expects the display will be available in 2019.

Founded in 2005, DigiLens has developed a proprietary waveguide manufacturing process which allows the company to “print” light manipulating structures (Bragg gratings) into a thin and transparent material wherein light can be guided along the optic and be made to project perpendicularly, forming an image in the user’s eye. While DigiLens isn’t the only company which makes waveguide displays, they claim that their process offers a steep cost advantage compared to competitors. The company says they’ve raised $35 million between its Series A and B investment rounds.

While DigiLens’ displays have primarily been used in HUD-like applications, the company is increasingly positioning its wares toward the growing wearable, AR, and VR industries. At AWE 2018 last week, DigiLens Founder & CTO Jonathan Waldern told me that the company expects to offer a waveguide display suitable for AR and VR headsets which could offer a 150 degree field of view between both eyes. He said that a single display could be suitable for AR and VR modes in the same headset by utilizing a liquid crystal blackout layer which can switch between transparent and opaque, something which DigiLens partner Panasonic has developed. A clip-on light blocker or other type of tinting film ought to be suitable as well.

Without saying anything this device will let you talk to your computer — https://www.weforum.org/…/computer-system-transcribes-words…

MIT researchers have developed a computer interface that can transcribe words that the user concentrates on verbalizing but does not actually speak aloud.

The system consists of a wearable device and an associated computing system. Electrodes in the device pick up neuromuscular signals in the jaw and face that are triggered by internal verbalizations — saying words “in your head” — but are undetectable to the human eye. The signals are fed to a machine-learning system that has been trained to correlate particular signals with particular words.

Researchers from the Georgia Institute of Technology have built a flexible, wearable oral sodium sensor that could help monitor a person’s sodium intake.

A leading cause of hypertension is a person’s uncontrolled salt intake. This often results in high blood pressure and heart complications.

As a solution, the Georgia Institute of Technology researchers built the oral sodium sensor that could be easily worn in the mouth to monitor salt intake.

It will still be a while before scientists are able to harness Superman-like laser vision, but the technology is now closer than ever before thanks to a new development from the University of St Andrews. The team there have created an ultra-thin membrane laser using organic semiconductors, which is for the first time compatible with the requirements for safe operation in the human eye. Even though the membrane is super thin and flexible, it’s durable, and will retain its optical properties even after several months spent attached to another object, such as a bank note or, more excitingly, a contact lens.

The ocular laser, which has so far been tested on cow eyes, is able to identify sharp lines on a flat background — the ones and zeros of a digital barcode — and could be harnessed for new applications in security, biophotonics and photomedicine. Team member Professor Malte Gather said: “Our work represents a new milestone in laser development and, in particular, points the way to how lasers can be used in inherently soft and ductile environments, be it in wearable sensors or as an authentication feature on bank notes.”
