lithium 3400mah 3.7v 18650 battery!US develops self-powered sensor to reduce battery consumption

　　The core component of new energy vehicles is the power battery. However, cruising range is still the bottleneck faced by the development of battery technology today. How to reduce power consumption to improve battery endurance has also attracted people's attention. Researchers at the University of Florida have developed a new type of sensor that does not require battery power to operate, thus reducing the power consumption of car batteries.

　　Jennifer Andrew, one of the professors who developed the sensor, said, "Cars are gradually becoming electric. How to minimize battery consumption is a huge project. Low-power sensors are needed for all devices." Nowadays, Sensors are used in everything from ignition systems to power windows. Therefore, it would be very important to have a power supply that does not rely on battery power.

　　According to Jennifer Andrew, the technology was inspired by nanowire manufacturing materials because nanowires can power sensors and are very efficient. By changing its internal properties, nanowires with stronger magnetoelectric coefficients are created, which can generate stronger electrical pulses, giving the sensor the basis for self-powered operation.

　　In fact, there have long been cases of "making a fuss" about sensors to achieve the purpose of saving power consumption. While conducting project research for the U.S. Department of Advanced Research Projects Agency (DAPRA), the Northeastern University research team also introduced a new sensor that can stop power consumption and rest on its own. This kind of sensor uses the principle of infrared detection to realize intelligent power supply. When there is an infrared signal, the sensor automatically turns on, and when the signal disappears, the sensor automatically sleeps. Although the principle of the "self-powered" sensor technology is different from that of Florida State University, the background is unified in order to reduce battery consumption.
