Super-absorbent film may lead to sweat-powered wearable electronics

Sweat is important for keeping us cool, but too much of it isn’t very pleasant either. Now, researchers at the National University of Singapore (NUS) have developed a new film that can absorb sweat – and better still, potentially use the moisture to po… Continue reading Super-absorbent film may lead to sweat-powered wearable electronics

ArcX ring lets phone-using athletes keep their hands on the action

There are many sports where both of your hands are occupied, making it difficult to remotely control your smartphone – even if you’re using a smartwatch. The ArcX Sports Ring, which will make its debut at CES 2021 later this month, was designed to reme… Continue reading ArcX ring lets phone-using athletes keep their hands on the action

Google-Glass-like smell stimulation device proposed as dementia therapy

It's hoped a prototype wearable device will allow clinical trials to test whether olfactory stimulation can help treat neurodegenerative disease

A novel wearable device has been proposed to deliver electrical pulses stimulating the olfactory system as a way of preventing or slowing dementia-related neurodegeneration. A dysfunctional sense of smell is suspected to be one of the earliest signs of Alzheimer’s and Parkinson’s so it is hypothesized these diseases could be prevented by olfactory stimulation.

Experimental “Faraday fabric” blocks almost all electromagnetic waves

Researchers at Drexel University have created “Faraday fabrics” that can block almost all electromagnetic waves. The key ingredient is a 2D material called MXene, and the development could help protect wearables from interference and people from potent… Continue reading Experimental “Faraday fabric” blocks almost all electromagnetic waves

Wearable inflatable SeeArch pops up for open-water rescues

If you should become separated from your solo sailboat, kayak or other watercraft out on the open sea, staying afloat isn’t the only challenge – you also have to be seen by your rescuers. That’s where the wearable, inflatable SeeArch is made to come in… Continue reading Wearable inflatable SeeArch pops up for open-water rescues

Circuit Boards You Can Stretch: Liquid Metal Nanomaterials Make a Strange Flex

If you think polyimide-based flexible PCBs are cool, wait until you get a load of what polymerized liquid metal networks can do.

Seems like [CNLohr] has some pretty cool friends, and he recently spent some time with a couple of them who are working with poly LMNs and finding out …read more
