The barometer in your phone and the tire pressure monitoring system in your car are both powered by a “compact yet precise” MEMS pressure sensor. It operates based on the piezoresistive effect of silicon, measuring only in millimeters, yet it can accurately sense pressure changes. This design document from Wang Dajun’s team breaks down the … Read more
If you are a professional in the fields of industrial automation, electronic scale manufacturing, or logistics equipment, understanding the internal structure of weighing sensors can help you select more accurately and maintain more efficiently! This article will break down the core components of this “weight translator” in simple language, revealing how it transforms pressure into … Read more

The first pointer meter used to detect current was called a galvanometer, invented in 1820. When used in conjunction with a Wheatstone Bridge, it can compare an unknown resistance and voltage to known voltages and resistances, thereby measuring related voltages, currents, and resistances. This method of measurement in the laboratory is time-consuming and labor-intensive, making … Read more
