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

Jennifer Andrew, one of the professors who developed the sensor, said, "The gradual development of electric vehicles, how to minimize battery power consumption is a huge project, and low-power sensors are required by all devices." It is the ignition system, power windows and other links that use sensors. Therefore, it is very important if there is no reliance on battery power for power supply.

According to JenniferAndrew, the inspiration for the technology came from nanowire fabrication materials, which are capable of powering sensors with high efficiency. By altering 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 already been cases of "making a fuss" on the sensor to achieve the purpose of saving power consumption. The Northeastern University research team also introduced a new type of sensor that can stop power consumption and self-rest when doing project research for the U.S. Department of Specialty Advanced Research Projects Agency (DAPRA). This 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 is different from the "self-powered" sensor technology at the University of Florida, the background is unified, and it is all about reducing battery power consumption.
