When people are trapped in the deep mountains and fields without food and water, people do not seem to have many ways to survive. However, the TV survival expert, Bei Ye, showed us a way to save our lives - drink urine. In addition to letting us live, this liquid also has other emergency uses, such as powering the device and sending a distress signal outside.
The team of Ioannis Ieropoulos at the University of the West of England in Bristol, United Kingdom, made a magic sock based on the emergency use of urine. It is understood that the urine of a bladder (about 648 ml) will enter the microbial fuel cell equipped in the socks through the integrated tube, and the bacteria contained inside the battery will generate electricity after taking up the nutrients in the urine.
During the lab's testing, the power generated by this power generation system has enabled wireless transmitters to send the "world's first wearable microbial fuel cell" message every two minutes.
In fact, using urine to generate electricity is nothing new. Previously, the team of Ioannis Ieropoulos successfully used a microbial fuel cell and their donated urine to successfully drive a cell phone, a paper emitter, and a 3D printed machine heart. However, the researchers found that they needed an electric pump to meet the nutrient requirements of the microbes inside the cell, which also limited the urine power generation.
In order to be able to build a wearable device that is self-sufficient, can work anywhere and does not require external facilities, the research team developed a pedal-powered electric pump that was inspired by the way blood fish circulates. This pedal-type electric pump uses a flexible silicone tube and is wound underneath the heel and is connected to a microbial fuel cell near the ankle. When the user walks, the tube will be squeezed to achieve continuous supply of urine.
Heather Luckarift, a US Air Force biotechnology developer from Ohio Global Technology, said: "This will signal the upcoming prosperity of wearable electronics, a flexible microbial fuel cell that can increase the wearable capability to one New level."
However, he also raised his own question: "At present, I do not know how urine enters the power supply system. In other words, how do users urinate into their socks?" In fact, this practice has been Difficulties, but the R&D team stated that they have developed a supporting implementation plan. "The clothes or other equipment we design will have an excretory system. There is no need to worry about urine collection and disposal."
For example, wearable microbial fuel cells can play a big role in military, space, skiing, and even outdoor apparel. In the future, such batteries will bring more uses to smart textiles.
In addition, we can also use this kind of urine-powered method for emergency assistance. When someone unfortunately encounters an air crash or a bloody collapse, as long as the person is still alive, he can power his device through urine and send his personal coordinates.
Aluminum window screen is a high-quality fiber mesh used to make doors and windows, usually made of aluminum alloy materials. Aluminum window screens are waterproof, corrosion-resistant, and abrasion-resistant, while keeping insects and other pests out of the room while keeping air and sunlight flowing. It is a commonly used door and window guardrail in the field of home and construction, which provides safety and convenience for people and prolongs the service life of home and building facilities. Aluminum alloy window screens can also be customized in size and color according to needs to match the appearance of the building and improve the appearance quality of the building.
