Mind Meld: Brain-Computer Interfaces Unlock the Future (2024 and Beyond!)

Posted by in categories: biotech/medical, computing, cyborgs, neuroscience, wearables

Further, “the necessity to secure private ideas, plans, and brain data from unpermitted viewing is accorded to Dr. Anita S Jwa by the phrase,” she argues. Besides that, the ethical implications in the fields of informed consent, coercion, and fairness with respect to the common attributes of the BCIs must be critically considered. For example, consider a scenario where a BCI is used to control a prosthetic limb. Without proper privacy measures, “unauthorised access to the BCI could lead to manipulation of the prosthetic limb,” posing risks to the user’s safety and autonomy.

Overcoming these difficulties requires the joint efforts of all the stakeholders, such as researchers, policymakers, and industry leaders. In the same way, we have to critically assess the technical, ethical, and accessibility issues in BCI. We may then be able to capture the potential of these BCIs and ultimately improve human lives.

In this instance, just imagine that we are submerging into the future of BCIs, and to my surprise, it feels like living in a movie where sci-fi is a reality! BCIs are going to be able to do all kinds of really advanced things very soon. People are going to think that they are very cool. We are entering an entirely new realm of brainy gadgets that are becoming smaller, sleeker, and oh-so-wearable. It is now all gear change; the future of BCI is almost as organic as slipping on your dream pair of sunglasses.

MemPal: Wearable Memory Assistant for Aging Population

Posted by in categories: biotech/medical, mobile phones, robotics/AI, wearables

We’re living in an aging society with cognitive loss placing stress on caregivers to monitor older adults struggling with memory decline.

MemPal is a wearable voice-based memory assistant that helps older adults live more independently and safely at home while also reducing caregiver burden. MemPal uses AI to automatically log the user’s actions in real-time based on visual context from a wearable camera without storing any image data, thereby preserving user privacy. With this activity log, MemPal helps older adults recall locations of misplaced objects and completion of past actions using simple voice-based queries such as “Hey Pal, where is my phone?” Additionally, MemPal provides context-based proactive safety reminders (e.g., “you may have forgotten to turn off the stove” or” you already took your medicine an hour ago”) and automatically tracks the completion on the MemPal app, allowing for remote monitoring by caregivers. Lastly MemPal can generate an automatic, summarized diary of activities for caregivers that may also prove useful for physicians to better understand patient behavior within their home.

MemPal was tested within the homes of 15 older adults (ages 65+). Our study demonstrated improved performance of object finding with audio-based assistance compared to no aid and positive overall user perceptions on the designed system. We discuss future design guidelines to adapt these types of wearable systems to various older adults’ needs.

Epilepsy is first use case for eyelid wearable

Posted by in categories: energy, health, internet, wearables

The wearables market has been dominated, so far, by smartwatches and fitness trackers. The first Apple Watch was launched in April 2015, and wearable technology now includes jewelry that tracks your steps and notifies you of an incoming call, VR headsets for gamers, earbuds, smart glasses with Internet access, smart clothing integrated with electronic devices and a range of health monitors.

But the world’s first eyelid wearable device opens up a whole new world of opportunity.

Blink Energy’s device weighs just 0.4 grams (0.014 ounces) — less than half the weight of a paperclip – and is fitted to one eyelid. You barely notice it, says Bar-On. “After two minutes you forget it’s there.”

New substrate material for flexible electronics could help combat e-waste

Posted by in categories: health, robotics/AI, sustainability, wearables

Electronic waste, or e-waste, is a rapidly growing global problem, and it’s expected to worsen with the production of new kinds of flexible electronics for robotics, wearable devices, health monitors, and other new applications, including single-use devices.

A new kind of flexible substrate material developed at MIT, the University of Utah, and Meta has the potential to enable not only the recycling of materials and components at the end of a device’s useful life, but also the scalable manufacture of more complex multilayered circuits than existing substrates provide.

The development of this new material is described in the journal RSC Applied Polymers (“Photopatternable, Degradable, and Performant Polyimide Network Substrates for E-Waste Mitigation”), in a paper by MIT Professor Thomas J. Wallin, University of Utah Professor Chen Wang, and seven others.

Wearable sensors help athletes achieve greater performance

Posted by in categories: transportation, wearables

Today’s athletes are always on the lookout for new techniques and equipment to help them train more effectively. Modern coaches and sports trainers use intelligent data monitoring through videos and wearable sensors to help enhance athletic conditioning. However, traditional video analysis and wearable sensor technologies often fall short when tasked with producing a comprehensive picture of an athlete’s performance.

Researchers from Lyuliang University have developed a low-cost, flexible, and customizable sensor for badminton players that overcomes current constraints. The work is published in APL Materials.

Badminton is known for its many technical movements and the dynamic speed and precision required to play successfully. Monitoring the postures, footwork, arm swings, and shown by badminton players is limited by video shooting angles and the discomfort of rigid .

A new material for small electronics that gives batteries longer life

Posted by in categories: military, wearables

Scientists have achieved a series of milestones in growing a high-quality thin film conductor, suggesting in a new study that the material is a promising candidate platform for future wearable electronics and other miniature applications.

Researchers at The Ohio State University, the Army Research Laboratory and MIT determined that the material is the best among similarly built films for its electron mobility—an index of how easy it is for an electrical current to pass through it.

Coupled with low defect density to reduce interference with electron movement on the surface, the material is like a tiny empty freeway where all the electrons can easily get where they need to go with no traffic to be seen.

Posted by in categories: bioengineering, energy, health, wearables

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 health care 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’s Department of Mechanical Engineering have shown that a health care device can be powered using alone. By combining a pulse oximetry sensor with a flexible, stretchable, wearable thermoelectric energy generator composed of , semiconductors, and 3D printed rubber, the team has introduced a promising way to address battery life concerns.

“This is the first step towards battery-free wearable electronics,” said Mason Zadan, Ph.D. candidate and first author of the research published in Advanced Functional Materials.
