Year end inventory: the eight popular new sensor technologies in 2016

sensors are the general name of devices or devices that can feel the specified measured signals and convert them into usable output signals according to certain rules. It is usually measured as a non electric physical quantity, and the output signal is generally electric 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 put sensor technology in the same position as communication technology and computer technology

with the development of modern science, sensing technology, as an emerging discipline closely related to modern science, has also developed rapidly, and has been more and more widely used in industrial automation measurement and detection technology, aerospace technology, military engineering, medical diagnosis and other disciplines. At the same time, it also promotes the development of various disciplines. With the technological progress of MEMS, laser technology, high-tech materials, etc., the research and development of sensors presents a diversified trend. Some use biological materials to simulate human skin and innovate the touch of sensors; Some use MEMS technology to develop micro intelligent sensors, which is conducive to the integration of complex systems; Some use high-precision laser technology to create lidar, which is conducive to the system to perceive the surrounding obstacles and environment in real time. The following is an inventory of the popular new sensor technologies in 2016

new wearable sensing technology

the British Ministry of defence (MOD) announced a new wearable sensing technology to locate soldiers and prevent accidental injuries. This dismounted close combat sensing (DCCS) system allows commanders to locate soldiers without GPS, while providing better ambient awareness

the camera, laser sensor, direction sensor, etc. equipped with the DCCS system on the wearable equipment of soldiers can be removed if necessary to locate some target objects, such as some military UAVs, military aircraft and the wounded in need of rescue. DCCS system equipment is placed around them, so that the troops with the same system equipment can quickly receive the target position

new artificial hair sensor

hexiaodong, a professor of materials science at Harbin Institute of technology in China, and his colleagues have made innovations in this area. The new technology they developed can imitate the fine hairs on the human surface. It is through these hairs that humans transmit sensory information to 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 is to bring external information to the artificial skin

of course, such wires do not feel pressure or movement changes like real hair. It judges the change of external environment through displacement. The wire itself has a small amount of charge, which will form a small magnetic field. When one or more wires are moved, the magnetic field around them will change accordingly. The researchers found that the sensitivity of the device was so high that it could even detect a fly. It can also detect objects passing through the surface and even feel a slight wind

researcher Yang Gong pointed out that the key to innovation lies in the selected wire material. Researchers have previously used carbon nanotubes to make artificial hair, but the effect is not ideal. The research team used glass cladding made of conductive cobalt alloy. The wire made of this material has high toughness and can be tied at will without breaking. The research team believes that this kind of "if we can reduce the expansion coefficient of tree fat by adding graphene, the durability and economy of the material are enough to make it popular in the real world.

" socks "temperature sensor

siren care, a startup dedicated to the health monitoring of diabetes patients, has developed a smart sock, which uses a temperature sensor to detect whether patients have inflammation, Then real-time detection of the health status of diabetes patients. Compared with the boots and insoles developed by other companies before, siren's socks are closer to the skin. The sensor is woven into the sock to detect foot inflammation at any time, and all the detected information will be uploaded to the smart app, so that patients can know their own foot conditions at any time

all data is stored in sock's sensor, app and cloud disk. When the foot is damaged, the socks can detect the high temperature difference, and then the app will send an alarm to remind the patient of the foot problem. Although smart socks are a sensor wearable device, they do not need to be charged frequently. The built-in battery of each sock is fully charged and can be used for six months

sticker sensor

it is reported that American researchers have developed a flexible sensor similar to skin stickers, which can monitor heart rate and recognize speech. Potential applications of the device include diagnosing diseases, manipulating robots, and playing computer games without a handle. For example, users only need to say "up, down, left, 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. It is only 20mm thick and weighs 213.6mg. It has enough flexibility and extensibility and can be worn on the bending parts of the human body such as the neck. Compared with the common stethoscope sensor, the low power 8 battery acupuncture experimental machine used by the sticker sensor: the allowable application is 0 ~ 35 ℃; Rate commercial micro electromechanical system (MEMS) accelerometer is wrapped in viscous elastic silica gel, which has strong wearability

bioluminescence sensor

bioluminescence sensor is actually a new research method, which was invented by a group of scientists at Vanderbilt University through genetic modification of luciferase, a biological enzyme. According to the researchers, this new sensor can be used to track the internal interaction of large neural networks in the brain

Professor Carl Johnson, the leader of the research group, said: "for a long time, neuroscientists have relied on electrical signals to record the activities of neurons. Although this method can achieve good detection results, it can only be used for a small number of neurons. Our new method can use optical technology to record the activities of hundreds of neurons at the same time."

adhesive skin sensor

it is reported that Japanese researchers have recently invented a cheap 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 the amount of human activity, the number of heartbeats and the intensity of ultraviolet rays. It can be used in health management, IOT and other fields

according to the researchers, the pasteable skin sensor is printed on a thin plastic film with the newly developed printing technology, and the cost is very low compared with the previous semiconductor sensor manufacturing technology. From the health point of view, the film directly attached to the skin can be used once, while the more expensive electronic components such as transistors are designed to be reusable, taking into account the convenience of use and low cost

artificial light sensor

in recent years, the use of biological "bioprocess" has become increasingly important in the production of bioenergy related substances and pharmaceuticals. The ability of blue-green algae to produce a variety of substances by photosynthesis has attracted much attention. On November 24, Tokyo a & M University announced that it had successfully developed an "artificial light sensor" for gene expression induced by red light by transforming the light sensor protein derived from blue-green algae

this research achievement is based on the concept of "synthetic biology" that uses DNA recombination technology to design and create organisms with new functions. By applying the successful technology that can change the gene expression control function using light to blue-green algae and other microorganisms that can produce useful substances, it is expected to rapidly promote the development of new biological processes with high functions

small EMG sensor

sensor has been playing an important role in the medical and health field because it is at the forefront of data collection. The small EMG sensor developed by Shanghai Chengdian Technology Co., Ltd. has been successfully applied in rehabilitation medicine and bionic prosthetics. In the future, it will be expanded to VR/AR, sports fitness, human exoskeleton and other sunrise industries

the EMG sensor independently developed by Shanghai Chengdian is a kind of charge sensor, which has the characteristics of high sampling rate, strong anti-interference ability and good filtering effect. Its core algorithm can transform the collected effective EMG data into clear waveform through filtering, and then apply it to rehabilitation, fitness, VR \ AR and other fields through waveform processing. At present, it has passed the national class II medical device quality inspection


the 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 the stage of independent design and innovative development, there are still many challenges in China: lack of core technologies in high-end fields, insufficient high-end talents, low automation and scale capacity of production, packaging and testing, lack of leading enterprises, and low sensitivity to new technologies, new products and new applications

in order to improve the competitiveness of sensors in China, we should focus on the system. We should do the signal processing and transmission of sensors together, and the system should do traction. From tracking and imitation, laying a solid foundation to the later demand of the demand side for system traction production, the test pieces are subject to great additional strain and the industry is rapidly crushed
