This is clearly aimed at Wearable AI such as the Ray-Ban Meta Wayfarers and other similar devices.

I was wondering how large of a language model can you fit in a pair of sunglasses?

Meta AI researchers have unveiled MobileLLM, a new approach to creating efficient language models designed for…

Key innovations in Meta’s MobileLLM include prioritizing model depth over width, implementing embedding sharing and grouped-query attention and utilizing a novel immediate block-wise weight-sharing technique.

While using the Meta AI chatbot on WhatsApp it answered my query with some great advice.

It almost felt like I had some support from a good friend.

I was kind of taken aback by the answer. Since I purchased the Ray-Ban \ Meta Wayfarers I have jokingly told people that I am wearing a large language model on my face. I came to find out that information is incorrect.

Meta AI responded, “That’s a cool device! Unfortunately, I’m not compatible with the Ray-Ban Meta smart glasses (yet!). I exist solely as a text-based AI assistant, so you can’t talk to me directly through the glasses.”

Finding ways to connect the human body to technology could have broad applications in health and entertainment. A new “electric plastic” could make self-powered wearables, real-time neural interfaces, and medical implants that merge with our bodies a reality.

While there has been significant progress in the development of wearable and implantable technology in recent years, most electronic materials are hard, rigid, and feature toxic metals. A variety of approaches for creating “soft electronics” has emerged, but finding ones that are durable, power-efficient, and easy to manufacture is a significant challenge.

Organic ferroelectric materials are promising because they exhibit spontaneous polarization, which means they have a stable electric field pointing in a particular direction. This polarization can be flipped by applying an external electrical field, allowing them to function like a bit in a conventional computer.

Organic electrochemical transistors (OECTs) are neuromorphic transistors made of carbon-based materials that combine both electronic and ionic charge carriers. These transistors could be particularly effective solutions for amplifying and switching electronic signals in devices designed to be placed on the human skin, such as smart watches, trackers that monitor physiological signals and other wearable technologies.

In contrast with conventional neuromorphic transistors, OECTs could operate reliably in wet or humid environments, which would be highly advantageous for both medical and wearable devices. Despite their potential, most existing OECTs are based on stiff materials, which can reduce the comfort of wearables and thus hinder their large-scale deployment.

Researchers at the University of Hong Kong have developed a new wearable device based on stretchable OECTs that can both perform computations and collect signals from the surrounding environment. Their proposed system, presented in a paper published in Nature Electronics, could be used to realize in-sensor edge computing on a flexible wearable device that is comfortable for users.

In the age of technology everywhere, we are all too familiar with the inconvenience of a dead battery. But for those relying on a wearable healthcare device to monitor glucose, reduce tremors, or even track heart function, taking time to recharge can pose a big risk.

For the first time, researchers in Carnegie Mellon University have shown that a healthcare device can be powered using body heat alone. By combining a pulse oximetry sensor with a flexible, stretchable, wearable thermoelectric energy generator composed of liquid metal, semiconductors, and 3D printed rubber, the team has introduced a promising way to address battery life concerns.

One of the drawbacks of fitness trackers and other wearable devices is that their batteries eventually run out of juice. But what if in the future, wearable technology could use body heat to power itself?

UW researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient — it still functions even after being pierced several times and then stretched 2,000 times.

The team detailed these prototypes in a paper published in Advanced Materials (“3D Soft Architectures for Stretchable Thermoelectric Wearables with Electrical Self-Healing and Damage Tolerance”).
