Security labels without silicon can prevent theft. Still, no electronic sensor functions without a wireless connection. The power supply required for such devices has an impact on battery size. Which is why a Norwegian-based startup has developed a new circuit architecture for wireless chips, so that they work in the subthreshold region. At 3.3 volts, conventional components need around...

Edible furniture can supply important energy in emergencies. Our digestive system is crucial and requires regular examination - whether it’s by ultrasound, colonoscopy, or a mini camera that can be swallowed. Now, an Italian research team has developed an edible prototype to replace the metal batteries used in these devices. Acting as anode and cathode respectively, Vitamin B2 and...

Balancing cloud usage can keep emissions and energy costs at bay. Meanwhile, an English startup is aiming to reduce both in public swimming pools by building data centres near the baths and using their thermal discharge to heat the water. All that’s required is a digital boiler. The startup bears the costs for the electricity as well as the...

Sporting activities reduce cancer cells in our bodies and power our fitness trackers. Purifying wastewater, however, requires a lot of energy - or does it? Not according to a South Korean research team. Their multi-layered, printable membrane, which is not subject to size restrictions, could be used to generate electricity during the treatment process. Because the top polymer layer...

Cycling into the wind can be illuminating. A collection of small wind turbines in the ocean may generate electricity for entire towns. Using the patented technology developed by an American research team, renewable energy could soon be produced from the movement of water in the sea. Unlike mechanical systems like these, the water’s power doesn't actuate a single generator...

Warm walls help generate energy. Now, the startup of a Finnish research team is using sand to store solar- and wind electricity. The renewable energy powers a device that circulates hot air in a silo with some 100 tons of sand which heats up to 600-1000℃. This way energy can be stored for months without using lithium and cater...

An Indian startup is creating smog-free zones. Whales and mini-shrimps sequester CO2 on the ocean floor. And now, a thumbnail-sized, sustainable energy storage device developed by scientists at Cambridge University offers fresh hope for the environment. When charging, the supercapacitor’s negatively charged electrode absorbs CO2 from the air, which is bound in an electrolyte housing the second electrode. During...

Seawater provides for nomads and makes lamps shine bright. Miniature wind turbines in the ocean are equally productive. A Swedish company is using waves of 50 cm and higher to generate electricity. For environmental reasons, floating elements are attached to old jetties or breakwaters, and then connected with hydraulic pistons. The biodegradable liquid in the pistons is compressed by...
