Innovations: ‘Wireless Wearable Health Sensor’ Is Human Motion Powered

Gao has developed a new way to power wireless wearable sensors: He harvests kinetic energy that is produced by a person as they move around.

“Our triboelectric generator, also called a nanogenerator, has a stator, which is fixed to the torso, and a slider, which is attached to the inside of the arm. The slider slides against the stator during human motion, and, an electrical current is generated at the same time,” Gao says. “The mechanism is quite simple. Friction results in electrical generation. This is not something new, concept-wise.”

This energy harvesting is done with a thin sandwich of materials (Teflon, copper, and polyimide) that are attached to the person’s skin. As the person moves, these sheets of material rub against a sliding layer made of copper and polyimide, and generate small amounts of electricity. The effect, known as triboelectricity, is perhaps best illustrated by the static electric shock a person might receive after walking across a carpeted floor and then touching a metal doorknob.

Technology: ‘Nuro R2’ Self-Driving Delivery Vehicle Completes Test Drives In 3 States (Video)

Earlier this year, our self-driving delivery robot R2 became the first autonomous vehicle to receive an approved exemption from the US Department of Transportation.

R2 then became the second autonomous vehicle to receive a driverless testing permit in California. When the COVID-19 pandemic hit, we set up contactless delivery services with R2 at temporary care facilities in California to carry food, water, and medical supplies to patients and doctors with the goal of decreasing points of contagion.

Today, we’re excited to announce another first for Nuro. For the past few months, R2 has been testing on city streets fully autonomously in three different states. No drivers. No occupants. No chase cars.

Personal Technology: Comparing iPhone 12 Vs iPhone 12 Pro (WSJ Video)

To get those crazy-fast 5G speeds on Apple’s iPhone 12 and iPhone 12 Pro, you have to find the 5G. So WSJ’s Joanna Stern set up on the field at MetLife Stadium to put the new phones — including their cameras and improved durable body — through the paces.

Energy Of The Future: ‘Powering Cities With A Virutual Power Plant’

Residential solar panels and battery backups are becoming more and more popular as efficiency rises and costs sink. This explosion in distributed solar makes a new idea possible: virtual power plants, or a smart network of individual solar panels that can act like a big power plant when electricity is needed most. And as extreme weather threatens many communities, this idea is arriving in the nick of time.

Tomorrow’s Restaurant: Multiple Drive-Thru Lanes & Seatless Dining (Video)

Burger King unveiled its new prototype last month, a prototype that it began working on shortly after the pandemic began. It features a much smaller dining room, or no dining room at all, along with two or three drive-thru lanes, walk-up windows and curbside lanes. Some of the options allow for the complete removal of indoor seating.

Burger King’s latest restaurant design assumes that customers will not go back to dine-in service.

It’s not as if the Miami-based burger chain’s latest prototype doesn’t feature indoor seats. But its restaurants are 60% smaller, meaning a much smaller dining room. And one version of it replaces the dining room altogether with patio seating.

But the design is heavy on takeout options, an acknowledgement that consumers have been shifting that way for some time and then went all-in on takeout during the pandemic. It features two or three drive-thru lanes, with digital menu boards and merchandising. A “living wall” provides a view into the kitchen interior featuring Burger King’s broiler. And there’s an external walkup window on the glass façade.

Future Housing: Living ‘Off-Grid Modular’ In Southwest Australia

“I think it strikes a chord with people, living off the grid and being minimalist. I could build a McMansion…but it wouldn’t be interesting.” 

Each project is designed specifically for your spatial requirements, budget and site. Design and finish options are limitless, but every design is the result of genuine collaboration with you. We operate from our modular construction hub in Brooklyn, Victoria which includes an impressive factory used for manufacturing the modules. The rapid off-site modular construction forces a high level of documentation – which in turn means a higher degree of design resolution and greater control of the cost for you. The factory environment ensures the risk of weather and site delays are eliminated, allowing for a fixed timeline for design, construction and delivery. It also ensures a consistent level of quality.

We’re one of Australia’s leading off-site construction companies and with Modscape, you will get:

  • Innovative architecture that uses quality materials at a fixed price
  • A tightly controlled construction process that still allows for high levels of customisation
  • A modern, sustainable modular building that minimises environmental impact, but doesn’t compromise on design or quality
  • A project that is brought to life by the one team
  • An enjoyable and stress-free building process.
