“In a nutshell, if you take a piece of yarn and stretch it, it will generate electricity. Sew it into the top, without the need for an external power source, and people can breathe normally to generate electrical signals.†University of Texas at Dallas, Nano Research Dr. Carter Haynes said in an interview with a recent Chinese-foreign cooperative research published in the journal Science.
The yarn, called Twistron, is spun from a number of carbon nanotubes, and the diameter of a single carbon nanotube is 10,000 times smaller than the diameter of a human hair. In order to make the yarn highly elastic, researchers have continuously increased the twist to form a spring-like structure.
"These yarns are essentially a supercapacitor, but it doesn't require an external power source to charge," Dr. Li Na of the Nano Research Institute told the Science and Technology Daily. Because the carbon nanotubes differ from the chemical potential of the electrolyte, a portion of the charge is embedded when the yarn is immersed in the electrolyte. When the yarn is stretched, the volume is reduced, the charges are brought closer to each other, and the voltage generated by the electric charge is increased to obtain electric energy.
“When stretching at a frequency of 30 times per second, the yarn can produce a peak electric power of 250 watts/kg. A yarn that weighs less than the fly can illuminate an LED each time it is stretched.†Nano Research According to Dr. Bowman, one of the directors and author of the article, the power per unit weight of Twistron yarns can be increased by more than 100 times compared to other woven fiber.
It is worth mentioning that salt water can also act as an electrolyte. The output of the power generation yarn can be scaled up as the yarn volume increases and the number of yarns working in parallel increases. “If you reduce production costs, Twistron can eventually be used for wave power generation,†Bowman said.
It is reported that the most suitable application of carbon nanotube yarns is to supply power to sensors or IoT communication. “Based on our average output power, we only need 31 milligrams of yarn to transmit 2 kilobytes of data packets every 10 seconds for the Internet of Things within a radius of 100 meters.â€
·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
