#stretchable battery

[fatihulusoy]

Greetings yet again folks! Before today's news i should ask this: what would you think when wearable tech is mentioned? AR/VR glasses? A smart watch? a pair of fancy glasses? nfc based products or was it something else for you?

what if i tell you there is a battery that is so stretchable and bendable that can be tailored between linings of your clothes now what would you think?

Meet the age of stretchable batteries people!

in that case i should mention when people of today was so busy with nonsense politics and rightist or leftist ideas there were quite a race between the biggest tech schools and companies for manufacturing this tech such as apple, samsung, stanford, Yokohama National University, zotach (japan based wearable tech company), sydney's UNCW, Australian research comity and more.. you get the idea..

so what is this tech in its core?

basically building more softer and more long term reliable materials to replace our common daily use batteries

in term of materials it nearly uses our common li-on batteries but these are mainly works like electrodes and often use polymers, hydrogels, and other flexible materials for electrodes and electrolytes. we can see in recent inovations include the use of stretchable conductors like gold nanowires or carbon nanotubes.

BUT what these mambo, jambo, wombo, combo means for public eye?

much longer active use time, higher adaptability, flexible form factor yet lower energy and power density.

for now this tech has been used in certain medical implant cases, wearable techs, tv's, and watches for now but there is some attempts to imply this in to textile industry recently..

and japan is seems like ahead of the race for now with Zotac’s VR GO 4.0 backpack

this is a backpack pc and its power source is tailored between in entire foam/ fiber pad. this "pc" is specifically made for VR/AR and streaming which includes

11th Gen Intel Core Mobile i7-11800H processor, an NVIDIA RTX A4500 graphics card with 20GB of GDDR6 memory and 7,168 CUDA cores, 16GB (32GB maximum) of DDR4 RAM, an M.2 slot for storage, a 2.5′ SATA 3 hard drive/SSD bay for storage, three USB 3.1 Type-A ports, a single USB 3.1 type-C port, DisplayPort, and a 12V DC outlet, all powered by dual 86.4 watt-hour hot-swappable batteries.

like i said this tech is still under developement stage and people still trying to make this tech better than other compettitives...

time will show us what will it gonna be turn out at the end..

lastly.. see you guys tomorrow...

Soft, stretchy 'jelly batteries' inspired by electric eels

Researchers have developed soft, stretchable 'jelly batteries' that could be used for wearable devices or soft robotics, or even implanted in the brain to deliver drugs or treat conditions such as epilepsy. The researchers, from the University of Cambridge, took their inspiration from electric eels, which stun their prey with modified muscle cells called electrocytes. Like electrocytes, the jelly-like materials developed by the Cambridge researchers have a layered structure, like sticky Lego, that makes them capable of delivering an electric current. The self-healing jelly batteries can stretch to over ten times their original length without affecting their conductivity—the first time that such stretchability and conductivity has been combined in a single material. The results are reported in the journal Science Advances.

Meanwhile, existing electroencephalography (EEG) and electrooculography (EOG) devices, that can be used to assess mental workload by measuring brain waves and eye movements respectively, are wired, bulky and prone to erroneous measurements arising from movements. By contrast, the “e-tattoo” is a lightweight, flexible, wireless device. The black, wiggly path of the e-tattoo is composed of a graphite-based conductive material, and is attached to the forehead using conductive adhesive film. Four square EEG electrodes, positioned on the forehead, each detect a different region of brain activity – with a reference electrode behind the ear – while rectangular EOG electrodes, placed vertically and horizontally around the eyes, provide data about eye movements. Each of the stretchable electrodes is coated in an additional conductive material. The e-tattoo, which is bespoke and disposable, is connected to a reusable flexible printed circuit using conductive tape, while a lightweight battery can be clipped to the device. After finding the e-tattoo worked as well as traditional EEG and EOG devices for monitoring brain waves and eye movements the team tested the technology on six participants.

Stretchable, wearable device lights up an LED using only the warmth of skin

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 Aug. 30 in Advanced Materials. "I had this vision a long time ago," said senior author Mohammad Malakooti, UW assistant professor of mechanical engineering. "When you put this device on your skin, it uses your body heat to directly power an LED. As soon as you put the device on, the LED lights up. This wasn't possible before."
