The researchers used extrusion printing to manufacture the electrodes, interconnects, encapsulation, and insulation. Active layers were then spray painted on at room temperature. All in all, six layers were 3D printed to build a flexible and fully functioning display.
“OLED displays are usually produced in big, expensive, ultra-clean fabrication facilities,” said Michael McAlpine, senior author of the team’s new study. “We wanted to see if we could basically condense all of that down and print an OLED display on our table-top 3D printer, which was custom built and costs about the same as a Tesla Model S.”
You might not have to send your devices in (or buy replacement parts) if the display breaks — you could just make new screens yourself. University of Minnesota Twin Cities researchers have developed what they say is the first fully 3D-printed flexible OLED display. In theory, you wouldn’t have to depend on panels made at large, distant factories to build or repair your gadgets.
The new approach combines two methods of 3D printing to print the six layers needed for a functional display. The team used extrusion printing to make the electrodes, encapsulation, insulation and interconnects, while active layers were spray-painted at room temperature. Past attempts by various teams either had issues with light uniformity (consistency across the whole panel) or relied on techniques beyond 3D printing to put some components in place, such as spin-coating or thermal evaporation.
The prototype was just 1.5 inches wide and used just 64 pixels. Any practical uses would require much higher resolutions (a 1080p display requires over 2 million pixels), and the scientists also want to improve brightness. It might also take a while to adapt the technology for home use. The university used a custom 3D printer that costs as much as a Tesla Model S — it might take a while for the method to be viable on off-the-shelf printers, even including high-end models like FormLabs’ $4,850 3B+.
The vehicle showcased at the event was Model SD-03, which was a demonstration for the autonomous SD-05 which is currently under development. The company is aiming to kickstart its business with the latter after unveiling it as a flying taxi at the World Expo 2025 in Osaka. It is worth mentioning that SkyDrive has been tested for manned flights and recently got certified by the Japanese government. “SkyDrive recently advanced toward commercialization with the Japanese transportation ministry’s acceptance of its type certificate application, a major milestone that no other flying vehicle developers have reached in Japan”, the company said in its statement.
The model released by SkyDrive at the CES 2022 is a driver-only vehicle that runs on electricity and is equipped with eight propellers. As per SkyDrive’s description of the vehicle, it can carry a maximum weight of 400 kg and is capable of cruising at 40–50 kilometres per hour for five to ten minutes. The company had revealed the first prototype of its eVTOL in 2018 and conducted the first manned flight in 2020. According to a report by Interesting Engineering, more companies such as Lilium and Volocopter are also planning to kickstart their flying car business this decade.
iSun has won a massive solar canopy order. But who’s buying?
There are not many things I love more than a solar power canopy that charges an EV charging station. It’s all right there — transferring sunlight into electricity and then using that electricity to power a modern electric car; driving on sunshine.
So, it’s quite exciting to see that iSun (NASDAQ: ISUN) has been awarded a contract to provide 1,780 solar power canopies for EV charging stations. The problem is: we don’t have much more detail than that. We don’t know where these charging stations are and don’t know who is procuring the solar canopies.
Jan 7 (Reuters) — Tesla Inc (TSLA.O) Chief Executive Officer Elon Musk tweeted on Friday that the electric carmaker will raise the U.S. price of its advanced driver assistant software dubbed “Full Self Driving” to $12,000 on Jan. 17.
The 20% price rise comes less than two years since Tesla raised Full Self-Driving (FSD) prices to $10,000 from $8,000 in 2020.
“Tesla FSD price rising to $12k on Jan 17. Just in the US.” Musk tweeted.
RWE is using used lithium batteries from electric vehicles in the new storage unit. The 60 battery systems in the innovative storage unit on the site of the RWE pumped storage power plant in Herdecke, North Rhine-Westphalia, can buffer around 4.5 megawatt hours of electricity.
The surface coating of the BMW iX Flow featuring E Ink contains many millions of microcapsules, with a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. Depending on the chosen setting, stimulation by means of an electrical field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.
Just don’t expect to see this at your local BMW dealership anytime soon: the automaker says this is just an “advanced research and design project.”
The innovative paint scheme can be triggered at the touch of a button. Right now, the colors are limited to white, black, and grey. But despite the constrained palette, BMW says it could have implications for the efficiency of its electric vehicles.
Even though solid state batteries are seen as technology that could drastically improve today’s fully-electric vehicles, it seems the first vehicles to feature one won’t actually be EVs. This is at least true in Toyota’s case since the manufacturer has now confirmed that its first solid state-equipped vehicles will be hybrids expected to debut in two or three years’ time.
The news comes from Gill Pratt, Toyota’s chief scientist and head of the Toyota Research Institute, who made the announcement during an interview for Autoline. He also mentioned that the manufacturer has made progress with its solid state project and that development is on schedule.
He did not say which hybrid Toyota will get a solid state battery, but he did go on to explain why it won’t immediately offer solid state EVs. The main reason has to do with the size of the battery pack, which for a hybrid vehicle that still has an internal combustion engine, is considerably smaller than what you see in pure EVs.
