Juli sensor gives you the prospect of the sensor

Following the breaking of cutting-edge skills in the fields of data science, nanotechnology, microelectronics, and the needs of economic and social development, the four categories may become the key points for the future development of sensor skills.

One is wearable. According to the US ABI survey company, the number of wearable sensors will reach 160 million in 2017. Wearable devices represented by google glasses are the most valued hardware innovations. Google glasses have more than 10 kinds of sensors built in, including gyro sensors, accelerometer sensors, magnetic sensors, linear accelerometers, etc., which end up with some functions that traditional terminals can't finish, such as the user can complete the game with just one eye. photography. At that time, the use of wearable devices was expanding from a wider range of watches, glasses, shoes, etc., such as electronic skin. A few days ago, the University of Tokyo has announced a flexible wearable sensor that can be attached to the skin. The sensor is in the form of a film, and the unit area component is only 3 g/m 2 , which is about 1/27 of that of general paper, and the thickness is only 2 μm.

The second is driverless. The US IHS company pointed out that the use of sensor technology to promote the development of driverless is accelerating. In this category, google's unmanned vehicle project development has achieved the main effect, through the camera, radar sensor and laser range finder of the car, to generate real-time traffic information in the surrounding area of the car at a distance of 20 times per second. And use artificial intelligence software to analyze, guess the future intention of the relevant road conditions, and contact the google map for navigation. The google unmanned sedan has been granted access to the road in Nevada, Florida and California. Global car giants such as Audi, Mercedes-Benz, BMW and Ford have all opened up unmanned driving skills, and some models are close to mass production.

The third is health care and health monitoring. Many medical research institutions at home and abroad, including internationally renowned medical professional giants, have achieved major developments in the application of sensor skills to the medical field. For example, ROHM is currently developing a picture sensor using near-infrared light (NIR). The principle is to illuminate the near-infrared LED, and then use a special imaging element to take pictures of the reflected light, and obtain the picture by changing the wavelength of the near-infrared light. Picture processing makes blood vessels and the like appear more and more clearly. Some research institutions have developed in the manufacture of sensors capable of embedding or swallowing data in the body. For example, the Georgia Institute of Technology in the United States is developing an in-vivo embedded sensor with a pressure sensor and a wireless communication circuit. The device is composed of a conductive metal and an insulating film, and can detect changes in pressure according to the frequency change of the resonant circuit formed. It will dissolve in body fluids.

The fourth is industrial control. In 2012, GE stated in the "Industrial Internet: Breaking the boundaries between intelligence and machines" that intelligent sensors can connect humans and computers, and contact software and big data analysis to break the constraints of physics and data science, and will change the international The way of operation. The statement pointed out that the United States has set up an industrial Internet, and each occupation can achieve a 1% increase in power. In 15 years, the energy profession will save 1% of fuel (about 66 billion US dollars). In January 2013, GE installed more than 10,000 sensors in a battery manufacturing facility in New York to monitor data such as temperature, energy consumption, and air pressure at the time of production. Factory managers can obtain this data via the iPad, and then Production is supervised.

In addition, Dutch multinationals such as Shell and Fuji Electric have also taken action in this area.
