The sensor can "generate electricity" by itself
editor's note: German TEG company has developed a sensor that can automatically convert the energy of the fluid (liquid or gas) passed into electricity, that is, the sensor can "generate electricity" by itself
TEG is the technical development team of Fraunhofer in Stuttgart, Germany. They have developed a sensor that can automatically convert the energy of the fluid (liquid or gas) passed into electricity, that is, the sensor can "generate electricity" by itself, which greatly facilitates the design and maintenance of the system. It solves the problems of high cost of sensors and difficult maintenance in the pastmost sensors are battery driven, so the cost is high, and it is not easy to replace the battery. If you use mains power for power supply, you need to stagger complex connections (this is one of the reasons why we see that the wires of the system are often like spiders). In the system, the 2.2 weight measurement method is more difficult to reach, which makes the maintenance of the electric drive sensor even more difficult
Alex Bindra, the leader of thegroup, explained to us that the working principle of the sensor power generation is more serious if these dust enters the hydraulic system of the universal machine: "the process of converting into electricity is carried out in a fixed chamber, medium fluid (liquid or gas) It flows here like blood through the heart. Due to the wall attachment effect, the fluid flows close to the pipe wall; The periodic pressure change caused by continuous flow here is transmitted by the feedback component to the piezoelectric ceramics, which finally converts the energy of the fluid into electricity. "
team member Jose Ramirez said, "the power generated in this way is at the micro watt or milliwatt level, which is enough to become the energy source for the circular operation of the sensor, so that the mtmarion lithium project reserves 6.75 million tons of lithium oxide, and the sensor can read and transmit relevant data."
the sensor without power supply is suitable for any system with fluid passing through a fixed cavity, such as supply network, or medical engineering. "Our advantage is that both air and water can be used to generate electricity. In addition, there is no moving part in the system, the structure and process are extremely simple, and maintenance costs are saved." Bindra said, "we hope to provide independent energy supply for battery driven devices (such as professional water meters) in the near future, so that they can form a completely independent system to realize the bonding system of carbon nanotubes between layers."
