Modern technology not only requires sensors to have basic information collection and processing functions, but also high miniaturization and intelligence has become the basis for measuring their performance. In terms of market share, micro-sensors are currently the most successful and most practical micro-electromechanical devices, and have accumulated good application experience in automobiles and wearable devices. In addition, due to the small size, new function, easy mass production, and low cost per piece, the micro-sensor has a bright future prospect.
At the "2015 China Intelligent Hardware Innovation Competition" seminar, the editor was fortunate to hear a wonderful speech from the senior market engineer of the Murata company, He Shenjing. Regarding how the sensor realizes cross-border problems, He Shenjing said that many sensors with a long history have developed to the present, and the fields that can be involved in the traditional sense have already been exhausted by us. Today, with emerging industries such as the Internet of Things and intelligent hardware. The strength of the attack, the sensor can finally be confined to the original circle, and gradually move to new areas of development.

Then, Shen Shenjing listed many clear cross-border cases for us, such as "Murata Manufacturing Coach". This group of robots uses the latest sensing, communication and group control technologies to collectively perform synchronized actions.
The cheerleading robots are each about 36 cm high. The upper body is human and the lower body is spherical. It can walk in all directions. The robot is equipped with a gyroscope sensor that maintains balance, an infrared sensor that grasps the mutual position, and a wireless communication system that controls the operation.
The small robot danced with the music, constantly changing the queue, and there was no collision between the robots, and the dance movement was completed neatly.
Another typical case is an ultrasonic sensor. More than 70% of the cars in China and 100% of the cash machines in the country use Murata's ultrasonic sensors. He Shenjing said that these ultrasonic sensors are mainly used for ranging and counting of banknotes. It can accurately detect the distance between the target and the device, and feedback the signal in real time, which can be used to separate the true and false coins and the number of banknotes discharged from the cash outlet.
He Shenjing also said in the speech that there are still many examples of such cross-border, but most of the time we focus on the function of the product itself, and often do not understand its internal structure. It's like the current iPhone6 ​​is very hot, but how many people know that it uses a barometric pressure sensor - not only can be used to measure altitude, but also can be used as navigation aids to enhance GPS navigation accuracy.
For the so-called sensor crossover, Mr. He also explained another point of view, in addition to the application of the leap, the functional leap is another way worth trying. "Like I said the sensor we think can only be used in some aspects, but we can change the idea. From driving safety to sleep detection, what is the relationship between these two? I introduced Murata's acceleration sensor in car safety. Very strong, Volvo's S80 chose Murata's acceleration sensor for heart rate detection of intruders. They placed the acceleration sensor in the position of the rear seat. When the owner is not in the car, someone enters or touches the car. According to the heart rate to judge the behavior of this person, to see if it is too nervous and then decide whether it is automatic alarm." He Shenjing added. "Everyone sometimes heard that some careless mother put the child in the car, the child suffocated, if there is such a function, there will be no such tragedy, we can detect the child's heart rate and promptly give the mother a warning."
He Shenjing pointed out that I have always believed that professional people do professional things. The smart industry is a very meticulous field of division of labor. So, after we finish the basic work, what we have to do afterwards is the application aspect. Murata is now able to provide More than 3,300 sensors, but Murata is still working hard to build a green sensor network. Only by fully exerting our innovative spirit can we promote further leap in the industry.
