(Summary description)　　Sensors are the entrance to data collection and the "heart" of the Internet of Things, smart devices, unmanned driving, etc., and will usher in huge room for development. The types and applications of sensors are diverse and can be said to be ubiquitous. The number of sensors often represents the level of intelligence.   　　Nowadays, modern industrial production is developing in the direction of large-scale, fast, high-efficiency, low-consumption and environmental protection. The wireless sensor network will play a special role in the future intelligent production of enterprises with its advantages of flexibility, safety, reliability, convenience and low cost.   　　Sensor + railway: can be powered by rail vibration   　　Normally, the staff at the train crossing use hard-wire sensors to detect whether the train has arrived. This also means that they must lay communication and power lines to activate traffic lights and fences. But now, researchers at the University of Huddersfield in the UK have developed a miniature wireless sensor that uses rail vibration to power the sensor.   　　Researchers deploy a large number of wireless sensors at each crossing, and they can communicate with each other to form a wireless sensor network. When the researchers place the sensor on the side of the rail, it can obtain energy from the vibration of the rail and use it to transmit signals. If one of the sensors fails, the network will be able to regain the surrounding warning signals.   　　Sensors + unmanned sailboat: a powerful tool for ocean data tracking   　　Last summer, Saildrone worked with scientists from the National Oceanic and Atmospheric Administration to use unmanned ships to collect specific temperature, salinity, and ecosystem data on the Arctic glacier cover. If these data are collected manually, it is difficult to obtain.   　　The most distinctive feature of this ship is that it is unmanned. They are under the control of the command center's communications satellites and complete the tasks of collecting geographic data, monitoring fish activities, and collecting environmental information. In addition, every search unmanned ship is equipped with a large number of sensors to send a large amount of data back to the control center.   　　Sensor + automatic driving: accurate detection of driver fatigue   　　A few days ago, LittleSoftware used a brainwave sensor produced by NeuroSky in the United States for a demonstration. The sensor's data is sent to the smart phone by wireless communication, and one of the six emotions is displayed. Its algorithm is based on past research results using brain waves and the results of questionnaire surveys conducted by the company to ensure the accuracy of inferred emotions. Kawahara said, "We believe that research aimed at identifying the relationship between brain waves and emotions has a long history and has reached sufficient accuracy."   　　If you can understand the driver's emotions while driving in real time, you can adjust the control of multiple cars according to the emotions. For example, it is speculated that when the driver is agitated, he can play music that helps to soothe his emotions. After the realization of the self-driving car currently under development, if it is inferred that the driver is tired, it can be switched to the "automatic driving mode."   　　Sensor + bionic technology: accelerate the implementation of smart medical care   　　Based on the principle of sound vibration, Korean scientists have developed a nano-slit sensor derived from "real spider" bionics. The unique feature of this system is that the gap between the sensors has reached the nanometer level, which guarantees high sensitivity. In addition to being able to effectively exclude external noise, nano-sensors also need to be able to identify sounds in specific frequency bands with high accuracy. For example, the functions of measuring blood pressure and pulse in medical health need to make the sensor extra sensitive to a certain human body signal, rather than merely recording sound and vibration. Therefore, the editor thinks that the function lies not in many, but in precision. But I still look forward to seeing a "Spider-Man Sixth Sense" sensor in the future.   　　Sensors + Home Furnishing: Stirring a Wave of Smart Home Furnishing   　　The distance sensor is a sensor that uses the principle of "time of flight" to detect the distance of an object. With the increasing demand for ranging sensing in markets such as mobile phones, smart homes, robots, and drones, this product has received increasing attention. The laser ranging sensor was born in response to market demand.   　　At present, the largest application market for laser ranging sensors is smart phones. With the development of consumer electronics, smart phones, smart homes, drones and other products, there will be more and more applications for distance sensing technology in indoor environments. For example, faucets, soap d
