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 sensor
He 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 sensor
Siren 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 sensor
According 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%.
Car cable harness, also known as a wire harness, cable assembly, wiring assembly or wiring loom, is an assembly of electrical cables or wires which transmit signals or electrical power. The cables are bound together by connector, terminal, cable ties, sleeves, electrical tape, conduit, PVC tube, corrugate tube, string, or a combination thereof.
Commonly used in automobiles, as well as construction machinery, cable harnesses provide several advantages over loose wires and cables. For example, many aircraft, automobiles and spacecraft contain many masses of wires which would stretch over several kilometres if fully extended. By binding the many wires and cables into a cable harness, the wires and cables can be better secured against the adverse effects of vibrations, abrasions, and moisture.
