📌 TOPINDIATOURS Eksklusif ai: Electricity generated from compression: Nylon-film d

Researchers have become successful in generating electricity from compression using a flexible nylon-film device. RMIT University researchers’ device keeps working even after being run over by a car multiple times.

This achievement opens the door to self-powered sensors on our roads and other electronic devices.

The team also pointed out that nylon innovation support new technologies for traffic-management sensing on roads.

Certain materials can produce an electrical charge when they are squeezed

Researchers also revealed that certain materials – such as quartz, some ceramics and even bone – produce an electrical charge when they are squeezed, pressed or vibrated. This is piezoelectricity, coming from the Greek “piezein” meaning to press.

Modern vehicles rely on piezo components in fuel injectors, parking sensors, airbag systems and other functions. The latest innovation could provide a more durable alternative material for such components.

The team also claimed that the breakthrough tackles a long‑standing problem with energy‑harvesting plastics, which can produce power from movement but are often too fragile for real‑world use, while also reducing carbon emissions by using ambient energy naturally present in movement and pressure.

High-frequency sound vibrations used

Researchers used high-frequency sound vibrations while applying an electric field as the nylon solidified, helping its molecules form a more ordered structure. This technique enabled the nylon device to generate electricity each time it was bent, squeezed or tapped.

The team found a simple way to transform nylon into an energy generator that was “incredibly resilient”.

“This method could power next-generation devices that need to survive real-world stresses – whether that’s wearable tech, sensors or smart surfaces,” said Distinguished Professor Leslie Yeo from the School of Engineering.

Dr Amgad Rezk said the process offered significant advantages for industry, with an energy-efficient and scalable approach.

“We’re excited to see where prospective industry partners could take this technology, from flexible electronics to sports equipment.”

Nylon by itself does not convert movement into electricity efficiently, limiting its potential in powering everyday devices. The team used a durable industrial plastic called nylon‑11 that, unlike common nylons, can generate electricity from pressure when its molecules are carefully aligned, according to a press release.

The nylon films were flexible, tough and reliable, maintaining their ability to turn movement into power.

“Our nylon devices can harvest energy simply from compression during motion,” said Komljenovic.

“The thin-film devices are so robust, you can fold them, stretch them, even run a car over them – and they keep making power. This could mean new ways to charge small devices using compression from the movement of people, machines or vehicles.”

The researchers plan to scale up the technology for larger applications and exploring partnerships with industry to bring this innovation to market.

📌 TOPINDIATOURS Update ai: OpenAI Flagged a Mass Shooter’s Troubling Conversations

A grim scoop from the Wall Street Journal: an automated review system at OpenAI flagged disturbing conversations that a future mass shooter was having with the company’s flagship AI ChatGPT — but, despite being urged by employees at the company to warn law enforcement, OpenAI leadership opted not to.

The 18-year-old Jesse Van Rootselaar ultimately killed eight people including herself and injured 25 more in British Columbia earlier this month, in a tragedy that shook Canada and the world. What we didn’t know until today is that employees at OpenAI had already been aware of Van Rootselaar for months, and had debated alerting authorities because of the alarming nature of her conversations with ChatGPT.

In the conversations with OpenAI’s chatbot, according to sources at the company who spoke to the WSJ, Van Rootselaar “described scenarios involving gun violence.” The sources say they recommended that the company warn authorities local authorities, but that leadership at the company decided against it.

An OpenAI spokesperson didn’t dispute those claims, telling the newspaper that it banned Van Rootselaar’s account, but decided that her interactions with ChatGPT didn’t meet its internal criteria for escalating a concern with a user to police.

“Our thoughts are with everyone affected by the Tumbler Ridge tragedy,” the company said in a statement to the paper. The spokesperson also said that the company had reached out to assist Canadian police after the shooting took place.

We’ve known since last year that OpenAI is scanning users’ conversations for signs that they’re planning a violent crime, though it’s not clear whether it’s yet successfully headed off an incident before it happened.

Its decision to engage in that monitoring in the first place reflects an increasingly long list of incidents in which ChatGPT users have fallen into severe mental health crises after becoming obsessed with the bot, sometimes resulting in involuntary commitment or jail — as well as a growing number of suicides and murders, leading to numerous lawsuits.

In a sense, questions of how to deal with threatening online conduct is a longstanding question that every social platform has grappled with. But AI brings difficult new questions to the topic, since chatbots can engage with users directly — sometimes even encouraging bad bad behavior or otherwise behaving inappropriately.

Like many mass shooters, Van Rootselaar left behind a complicated digital legacy — including on Roblox — that investigators are still wading through.
