With the development of modern science, sensor technology as a new subject closely related to modern science has also been rapidly developed, and is increasingly widely used in industrial automation measurement and detection technology, aerospace technology, military engineering, medical diagnosis and other disciplines. Use, at the same time, promote the development of various disciplines. With the technological advancement of MEMS, laser technology, high-tech materials, etc., the development of sensors is diversified. Some use biomaterials to simulate human skin and innovate the touch of sensors. Some use MEMS technology to develop miniature intelligent sensors. Conducive to the integration of complex systems; some use high-precision laser technology to create a laser radar, which will help the system to sense the surrounding obstacles and the environment in real time. Below, I will give you a look at the new sensor technology that is popular in 2016.
A sensor is a generic term for a device or device that is capable of sensing a defined measurement and converting it into an available output signal in a certain pattern. Usually measured is a non-electrical physical quantity, and the output signal is generally a power quantity. The world today is facing a new technological revolution. The main foundation of this revolution is information technology, and sensor technology is considered to be one of the three pillars of information technology. Some developed countries have listed sensor technology as the same location as communication technology and computer technology.
New wearable sensing technology
The UK Department of Defense (MoD) has announced a new wearable sensing technology that locates soldiers and prevents accidental injuries. This set of Trekking Melee Sensing (DCCS) system allows commanders to locate soldiers without GPS and to provide better sense of the surrounding environment.
The DCCS system is equipped with a camera, laser sensor, direction sensor, etc. on the soldier's wearable device. If necessary, it can be taken off to locate some target objects, such as military drones, military aircraft, and wounded people who need assistance. By placing DCCS system equipment around it, the troops that also have the system equipment can quickly receive the target location.
New artificial hair sensorHe Xiaodong, a professor of materials science at Harbin Institute of Technology in 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. It is through these hairs that humans transmit sensory information to the skin nerves. The researchers used 30 micron thin wires instead of hair. They embedded a row of tiny wires in the silicone rubber. The purpose of this row of wires was to bring outside information to the artificial skin.
Of course, this kind of wire does not feel pressure or movement changes like real hair. It uses displacement to make judgments about changes in the external environment. The wire itself has a small amount of charge that creates a small magnetic field. When one or more wires are moved, the surrounding magnetic field changes accordingly. The researchers found that the device was so sensitive that it could even detect a fly. It can also detect that an object has been swept across the surface and can even feel a slight wind.
Researchers point out that the key to innovation is the choice of wire material. Researchers have previously used carbon nanotubes to make artificial hair, but the results are not ideal. The research team used a glass covered wire made of a conductive cobalt alloy. The wire of this material has a high toughness and can be knotted at will and does not break. The research team believes that the durability and economics of this material is sufficient to make it available in the real world.
"socks" temperature sensorSiren Care, 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.
All data is stored in the socks sensor, mobile app and cloud disk. When the foot is damaged, the sock can detect the high temperature difference, and then the App will give an alarm to remind the patient that there is a problem with the foot. Although smart socks are a sensor wearable device, they do not need to be recharged frequently. The internal battery of each sock is fully charged and can be used for six months.
Sticker sensorAccording to reports, American researchers have developed a flexible sensor similar to a skin sticker that monitors heart rate and recognizes speech. Potential applications for the device include diagnosing the condition, manipulating the robot, and playing computer games without a handle. For example, the user only needs to say "up, down, left, and right" to control the Pac-Man game, and the speech recognition rate can reach 90%.
It is reported that this new sensor is similar to a small band-aid, only 20 mm thick, 213.6 mg weight, with sufficient flexibility and extensibility to be worn on the curved part of the neck. Compared to common stethoscope sensors, the low-power commercial micro-electromechanical system (MEMS) accelerometers used in sticker sensors are wrapped in viscous elastic silicone and are highly wearable.
Bioluminescent sensorBioluminescence 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.
Research team leader Carl Johnson said: "For a long time, neuroscientists rely on electrical signals to record the activity of neurons. Although this method can be used for good detection, it can only be used for a small number of neurons. And our The new method can use optical technology while recording the activity of hundreds of neurons."
Stickable skin sensorAccording 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.
According to the researchers, the stick-on skin sensor is printed on a thin plastic film using the newly developed printing technology, which is relatively low in cost compared to previous semiconductor sensor manufacturing techniques. From a hygienic point of view, the portion of the film that is directly attached to the skin can be used at one time, while the more expensive electronic components such as transistors are designed to be reusable, taking into account ease of use and low cost.
Artificial light sensorIn recent years, in the fields of bioenergy-related substances and pharmaceutical production, the use of biological "biological processes" has become more and more important, and the ability to produce blue-green algae of various substances by photosynthesis has attracted much attention. On November 24, Tokyo University of Agriculture and Technology announced that it has successfully developed an "artificial light sensor" that induces gene expression by red light by modifying the photosensor protein derived from blue-green algae.
The results of this research are based on the concept of "synthetic biology" that uses DNA recombination technology to design and create new functions. By applying this successful technique for changing the gene expression control function using light to microorganisms capable of producing useful substances such as blue-green algae, it is expected that the development of new biological processes with high functions will be rapidly advanced.
Small myoelectric sensorSensors have always played an important role in the health care arena because they are at the forefront of collecting data. The small electromyography sensor developed by Shanghai Haodian Technology Co., Ltd. has been successfully applied in rehabilitation medicine and bionic prosthetic limbs. In the future, it will be extended to VR/AR, physical fitness, human bones and other sunrise industries.
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 core algorithm can convert the collected effective EMG data into a clear waveform through filtering, and then apply the waveform to the fields of rehabilitation, fitness, VR\AR, etc., and has passed the national second-class medical device quality test.
to sum upThe development of the sensor industry is inseparable from scientific research and innovation. Although China's sensor industry has gradually moved from imitation and introduction to independent design and innovation, there are still many challenges in China: the core technology in the high-end field is not mastered, the high-end talent is insufficient, production, The automation and scale of packaging and testing are low, lacking leading enterprises, and low sensitivity to new technologies, new products and new applications.
In order to improve the competitiveness of China's sensors, it should be based on the system. The signal processing and transmission of the sensors should be done together. The system should be traction. From the tracking and imitation, the foundation should be laid, and then the demand side should propose the system demand traction industry development.
