As a core component under the trend of artificial intelligence, sensors are indispensable in any application field. Under the impetus of the Internet of Things, in the face of the gradual popularization and development of intelligent home networks, various sensors are introduced into home appliances. Become more urgent.
Sensors have been widely used in various fields of social development and human life, such as industrial automation, agricultural modern ratio, aerospace technology, military engineering, robotics, resource development, marine exploration, environmental monitoring, security, medical diagnosis, transportation, Household appliances, etc. Among them, pressure sensors, temperature sensors, flow sensors, and level sensors have shown the characteristics of mature markets.
In the IoT era, sensors are the core of the IoT awareness layer and are the key elements that make up the Internet of Things. At present, there are about 22,000 kinds of sensors in the world. China has about 7,000 kinds of conventional types and varieties. More than 90% of high-end sensors are still heavily dependent on imports. Digital, intelligent and miniaturized sensors are seriously lacking. In the Internet of Things era, sensor technology is both an opportunity and a challenge. The Internet of Things era provides a wider application space for sensors, but it also puts more demands on sensors, such as smarter, smaller size, higher integration, lower system power consumption and segmentation for various industries. solution.
At the end of 2016, the State Council issued the “13th Five-Year Plan for the Development of Strategic Emerging Industriesâ€. The plan proposes to promote the research and development and industrialization of key technologies in the field of smart sensors. This undoubtedly shows that smart sensors and world-class high-end chips will be the focus of the Ministry of Industry and Information Technology in 2001.
As the most basic hardware in the era of intelligent sensing, the intelligent process is accelerating, and any connected intelligent terminal nodes are inseparable from sensors. As the field of sensor applications continues to expand, the sensor market will maintain rapid growth, especially wearable devices, automotive electronics, medical, Internet of Things, etc. will become the main growth point of sensors. Then, looking back at the entire 2016, what are the “black technology†new products that ignite the eye in the sensor market?
Molecular sensor
In the past, although there have been techniques for using chemicals in "invisible inks" that require encryption, it has been difficult to ensure that hidden information is not read without authorization. In response to this situation, David Margulis of the Weizmann Institute of Science in Israel and his research team have developed a fluorescent molecular sensor that can distinguish different chemicals by generating specific fluorescence emission spectra. Considering recent concerns about global electronic surveillance, this sensor provides a means of security that bypasses electronic communication systems.
2. Wireless sensor
In recent years, fitness trackers have become a more popular wearable technology product. However, engineers at the University of California at Berkeley took this concept one step further and developed tiny wireless sensors to detect health in the human body. It is reported that these devices have been reduced to a cubic millimeter of approximately one grain of dust, known as "neural dust." These sensors can be implanted in the body of a person where they can detect tissue, muscle and nerves in real time.
3. Bioluminescence sensor
Bioluminescence sensors are actually a new type of research method, which was invented by a group of scientists at Vanderbilt University in the United States by genetically modifying luciferase. According to the researchers, this new sensor can be used to track the internal interaction of large neural networks in the brain.
4. Artificial hair sensor
For humans, skin is not only a barrier to protect us from dust and bacteria, but also a medium for us to feel the changes in the external environment. As researchers develop robotics further, they are also working hard to create the same functionality as real skin for robots. He Xiaodong, professor of materials science at Harbin Institute of Technology, China, and his colleagues have innovated in this area. The new technology they developed can mimic the fine hair on the surface of the human body and transmit sensory information to the robot. The researchers used 30 micron thin wires instead of hair, and embedded a row of tiny wires in the silicone rubber, and the role of this row of wires is to bring outside information to artificial skin. The results of this research can be used to sense prosthetics or corresponding health care equipment.
5. Composite touch sensor
At present, most robotic touch sensors only have load cells, so they can only detect the hardness and texture of the object, which makes the robot's recognition of foreign objects very low precision. But if combined with traditional force sensors, the composite touch sensor helps the robot recognize the composition of the object. It is this principle that Georgia Tech's experts showcased the "skin" that they designed for robots to produce heat from conductive and non-conductive fabrics and thermistors.
6. Air sensor
TZOA has introduced a new air sensor. It is understood that this is a sensor that collects air quality information, including the type and quantity of particles and whether they contain harmful chemicals. And the device also protects the fetus and children from contaminants that affect brain development. In the future, the company plans to sell equipment for outdoor pollution in China and India, as well as equipment for indoor pollution in the United States. TZOA is also developing an asthma device that helps determine the triggering factors of asthma attacks.
7. Promote sleep "Sense" sensor
According to reports, James of London in England invented a sleep sensor called "Sense". It is understood that the "Sense" sensor can automatically adjust the light according to the owner's control, control the heating, and even play soothing music to promote human sleep, and adjust the environment to the most comfortable state during sleep. Sound, lighting, temperature, humidity, and air quality can also be monitored to score the user's sleep every night.
8. EMG sensor
Sensors have always played an important role in the health care arena because they are at the forefront of collecting data. The EMG sensor independently developed by Shanghai Yudian is a kind of charge sensor with high sampling rate, strong anti-interference ability and good filtering effect. The sensor has been successfully applied in rehabilitation medicine and bionic prosthetics, and will be extended to the VR/AR, physical fitness, and human bones in the future.
9. Temperature sensor
SirenCare, a founding company dedicated to the health monitoring of people with diabetes, has developed a smart sock that uses a temperature sensor to detect if a patient has inflammation and to detect the health of a diabetic patient in real time. Compared to the boots and insoles developed by other companies, Siren's socks are closer to the skin. The sensor is woven into the sock and the foot inflammation can be detected at any time, and all the information detected is uploaded to the app on the smartphone, so that the patient can know his or her foot at any time.
10. Skin sensor
According to reports, Japanese researchers have recently invented an inexpensive integrated sensor like a band-aid. This band-aid integrated sensor is a flexible device that can be attached to the body at will. It can monitor human activity, heart rate and UV intensity, and can be used in health management and Internet of Things. The stick-on skin sensor is printed on a thin plastic film using the newly developed printing technology. Compared with the previous semiconductor sensor manufacturing technology, the cost is low, and the convenience and low cost are taken into consideration.
With the popularity of environmental sensors in smart phones, wearable devices, and home appliances, environmental sensors will be broken in the automation and humanization applications of smart homes and environmental monitoring applications; with the application of sports and fitness health sensors in smart phones, The popularity and interaction of wearable and home health fitness devices will further enhance the family health and medical experience; and with the popularity of VR applications, the home entertainment experience will be rebuilt. The automation and humanization of environmental sensors and smart homes will be broken.
We believe that more “black technology†will emerge in 2017, and finally we will look at the world's major sensor manufacturers.
