The rapid development of wearable electronics requires its energy supply part to be flexible, wearable, integratable and sustainable. However, some of the energy supply units cannot meet these requirements at the same time, and there is also a capacity limitation of the energy storage units, and the development of sustainable wearable self-charging power supplies is crucial. Here, we report a wearable sustainable energy harvesting-storage hybrid self-charging power textile. The power textile consists of a coaxial fiber-shaped polylactic acid/reduced graphene oxide/polypyrrole (PLA-rGO-PPy) triboelectric nanogenerator (fiber-TENG) that can harvest low-frequency and irregular energy during human motion as a power generation unit, and a novel coaxial fiber-shaped supercapacitor (fiber-SC) prepared by functionalized loading of a wet-spinning graphene oxide fiber as an energy storage unit. The fiber-TENG is flexible, knittable, wearable and adaptable for integration with various portable electronics. The coaxial fiber-SC has high volumetric energy density and good cycling stability. The fiber-TENG and fiber-SC are flexible yarn structures for wearable continuous human movement energy harvesting and storage as on-body self-charging power systems, with light-weight, ease of preparation, great portability and wide applicability. The integrated power textile can provide an efficient route for sustainable working of wearable electronics.

Launching today, AItopia will explore AI’s impact on design, architecture and humanity both today and in the future. Dezeen features editor Nat Barker introduces the series.

The future has arrived. Having been depicted countless times in sci-fi literature and cinema over the decades, machines that can think for themselves are becoming a reality.

Artificial intelligence (AI) – that is, computers or contraptions performing tasks that would usually require a human brain – is a concept that has captured the shared imagination in some form since ancient times. But it was the British polymath Alan Turing who first seriously addressed the matter in his seminal 1950 paper Computing Machinery and Intelligence. “I propose to consider the question, ‘Can machines think?’” Turing wrote.

The age of generative AI is here: only six months after OpenAI’s ChatGPT burst onto the scene, as many as half the employees of some leading global companies are already using this type of technology in their workflows, and many other companies are rushing to offer new products with generative AI built in.

But, as those following the burgeoning industry and its underlying research know, the data used to train the large language models (LLMs) and other transformer models underpinning products such as ChatGPT, Stable Diffusion and Midjourney comes initially from human sources — books, articles, photographs and so on — that were created without the help of artificial intelligence.

Summary: Researchers mapped neural activity in an octopus’s visual system, revealing striking similarities to humans.

The team observed neural responses to light and dark spots, thereby creating a map resembling the organization of the human brain. Interestingly, octopuses and humans last shared a common ancestor around 500 million years ago, suggesting independent evolution of such complex visual systems.

These findings contribute greatly to our understanding of cephalopod vision and brain structure.

Humane, the top-secret tech startup founded by ex-Apple vets Imran Chaudhri and Bethany Bongiorno, just showed off the first demo for its projector-based wearable at a TED talk. Axios’ Ina Fried broke the news, and Inverse has seen a recording of the full TED talk given by Chaudhri.

Humane founder and ex-Apple designer Imran Chaudhri shared the first look at the company’s AI-powered wearable projector. Here’s an exclusive first glimpse of Humane’s screen-less iPhone killer in action and details on its many functions including making and receiving phone calls, summarizing notifications, and translating your voice in real-time.

Perovskite solar cells designed by a team of scientists from the National University of Singapore (NUS) have attained a world record efficiency of 24.35% with an active area of 1 cm2. This achievement paves the way for cheaper, more efficient and durable solar cells.

To facilitate consistent comparisons and benchmarking of different solar cell technologies, the photovoltaic (PV) community uses a standard size of at least 1 cm2 to report the efficiency of one-sun in the “Solar cell efficiency tables.” Prior to the record-breaking feat by the NUS team, the best 1 cm2 recorded a of 23.7%. This ground-breaking achievement in maximizing from next-generation will be crucial to securing the world’s energy future.

Perovskites are a class of materials that exhibit high light absorption efficiency and ease of fabrication, making them promising for solar cell applications. In the past decade, perovskite solar cell technology has achieved several breakthroughs, and the technology continues to evolve.
