With the breakthroughs in cutting-edge technologies in fields such as science and technology, nanotechnology and microelectronics, it is not enough for us to obtain information from the outside world by means of sensory organs and rely on people's own sense organs. In the study of natural phenomena and laws, as well as the production of sensors and the Internet of Things, their activities are far from enough. In order to adapt to this situation, we need the Internet of things sensors. The Internet of Things sensor is an extension of human facial features, also known as electricity Facial features The advent of the new technological revolution, the world began to enter the information age. In the process of using information, the first thing to be solved is to obtain accurate and reliable information, and the sensor is the main way and means to obtain the information in the field of nature and production. The following four areas may become the focus of the future development of sensor technology. First, wearable applications According to the forecast by ABI Research, the number of wearable sensors in 2017 will reach 160 million. Wearables, represented by Google Glass, are the most watched hardware innovations. Google glasses built as many as 10 kinds of sensors, including gyroscope sensors, acceleration sensors, magnetic sensors, linear acceleration sensor, to achieve some of the features can not be achieved with traditional terminals, such as the user only need to blink their eyes to complete the photo . Currently, wearable device applications are expanding from external watches, eyeglasses and shoes to a wider area such as electronic skin. Recently, the University of Tokyo has developed a flexible wearable sensor can be attached to the skin. The sensor is a thin film, weight per unit area of ​​only 3g / m2, is about 1/27 of ordinary paper, the thickness of only 2 microns. Second, driverless cars US IHS pointed out that the sensor technology to promote the development of unmanned applications are accelerating the breakthrough. In this area, Google has achieved significant results in the development of unmanned vehicle projects that generate real-time traffic information in the perimeter of the car at intervals of 20 times per second using in-vehicle cameras, radar sensors and laser range finders, And the use of artificial intelligence software for analysis to predict the future trends related to road conditions, combined with Google Maps for road navigation. Google driverless cars have been on the road in Nevada, Florida and California. Global auto giants such as Audi, Mercedes-Benz, BMW and Ford have all started research and development of driverless technologies, and some models are in the process of mass production. Third, health care and health monitoring Many domestic and foreign medical research institutions, including the internationally renowned medical giant, have made significant progress in applying sensor technology to the medical field. For example, Rohm Corporation is currently developing an NIR-based image sensor based on the principle of shooting near infrared light LED, capturing the reflected light with a special camera, obtaining the image by changing the wavelength of near infrared light, and then passing Image processing makes blood vessels and other more vividly presented. Some research institutes have made advances in sensors that can be embedded or swallowed into the body. For example, Georgia Institute of Technology is developing an in-cell embedded sensor with a pressure sensor and a wireless communication circuit. The device is made of a conductive metal and an insulating film, and can detect a change of pressure according to the change of the frequency of the resonant circuit formed. Will be dissolved in body fluids. Fourth, industrial control applications In 2012, in its report "Industrial Internet: Breaking the Boundary between Wisdom and Machines," GE proposed that the connection of human-machine interfaces through smart sensors combined with software and big data analysis can break through the limitations of physics and materials science and change the world The way of operation. The report also pointed out that the United States through the deployment of the industrial Internet, all industries can achieve 1% efficiency increase in 15 years, the energy industry will save 1% of fuel (about 66 billion US dollars). In January 2013, GE installed more than 10,000 sensors at a cell manufacturer in New York to monitor data such as temperature, energy consumption, and air pressure during production, and factory managers can access the data through the iPad, Production supervision. The ultrasonic weather station brings together seven sensors, providing first-class weather monitoring information for industrial production, providing reliable information for preventing some catastrophic events, increasing efficiency, reducing costs and total costs. IoT sensors have long been infiltrated in smart home, transportation, ring protection, logistics, food safety and other fields. The important role that IoT sensor technology plays in economic development and social progress is very clear. At present, development areas that all countries attach great importance to. I believe in the near future, sensor technology will be a leap in reaching a new height, to further promote the rapid economic development and improve our quality of life.
