In 2008, IBM proposed the concept of "smart cities", stating that building a smart earth requires three steps. Among them, step * is the application of sensors - embedding various innovative sensing technologies into objects and facilities, thereby greatly digitizing the material world.
The first White Paper on the Development of China's Sensor Industry (2014) shows that from 2009 to 2013, the average annual growth rate of the domestic sensor market exceeded 20%. It is predicted that the sensor market in China will steadily and rapidly develop in the next five years, with an average sales growth rate of over 30%.
10 robot cheerleaders who are 36cm tall and weigh 1.5KG, dressed in red cheerleading uniforms, and can dance. With their reverse pendulum control technology, ultrasonic position measurement technology, and group control technology, they dance to music and can form 12 neat and uniform formation styles, appearing to be about to fall but not fall, and appearing to be about to collide but not collide; The released Apple Watch is equipped with sensors such as gyroscopes and accelerometers to track the wearer's movements, thereby obtaining more comprehensive physical data; At the just concluded 2015 China Home Appliance Expo, home appliances also achieved intelligence through built-in sensors
Premier Li Keqiang pointed out in this year's government work report that it is necessary to formulate the "Internet plus" action plan to promote the integration of mobile Internet, cloud computing, big data, Internet of Things, etc. with modern manufacturing. As a fundamental element of the Internet of Things, sensors are considered the primary link in achieving automatic detection and control. The existence and development of sensors have given objects touch, taste, and smell, as if they had sensory organs such as eyes, tongue, and mouth, which can be activated through interconnectivity and data collection. Based on this, big data analysis can make future intelligent decision-making possible.
At present, acceleration sensors, gyroscope sensors, gravity sensors, and photoelectric sensors have been widely used in various fields such as smartphones, wearable devices, as well as automobiles and healthcare. Undoubtedly, the development and application expansion of connectors are accelerating from simple to complex, and will change our lives more widely.
