Ultrasonic transducer wind speedis a general term for devices or devices that can sense the prescribed measurement and convert it into a usable output signal according to a certain rule. Usually measured is a non-electrical physical quantity, and the output signal is generally electric quantity. 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 classified sensor technology as being on the same position as communication technology and computer technology.

New wearable sensing technology

The British Ministry of Defense (MoD) announced a new type of wearable sensing technology to locate soldiers and prevent accidental injuries. This set of walking close combat sensing (DCCS) system allows the commander to locate the soldier's position without GPS, while providing better surrounding environment awareness.

The DCCS system is equipped with cameras, laser sensors, direction sensors, etc. on soldiers’ wearable devices, which can be removed if necessary to locate some target objects, such as some military drones, military aircraft, and the wounded in need of assistance , Placing DCCS system equipment around it can allow troops that also have the system equipment to quickly receive the target location.

New type of artificial hair sensor

He Xiaodong, a professor of materials science at Harbin Institute of Technology in China, and his colleagues have innovated in this regard. They have developed a new technology that mimics the fine hairs 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 fine wires instead of hair. They embedded a row of fine wires in silicone rubber. The purpose of this row of wires was to bring external 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 on changes in the external environment. The wire itself carries a small amount of electric charge, which creates a small magnetic field. When one or more wires are moved, the surrounding magnetic field will change accordingly. The researchers found that the sensitivity of this device is so high that it can even detect a fly. It can also detect objects swiping across the surface, and even a slight wind can be felt.

The researchers pointed out that the key to innovation lies in the choice of wire material. Researchers previously used carbon nanotubes to make artificial hair, but the effect was not ideal. This time the research team used a glass covered wire made of conductive cobalt alloy. The wire of this material has high toughness and can be knotted at will without breaking. The research team believes that the durability and economy of this material are enough to make it popular in reality*.

"Sock" temperature sensor

Siren Care, a startup dedicated to monitoring the health of diabetic patients, has developed a smart socks that uses a temperature sensor to detect whether the patient has inflammation, and then detects the health of diabetic patients in real time. 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 socks, which can detect foot inflammation at any time, and all the detected information will be uploaded to the App on the smartphone, so that the patient can know the condition of their feet at any time.

All data is stored in the ultrasonic distance transducer of the sock, mobile apps and cloud disks. When the foot is damaged, the socks can detect the high temperature difference, and then the App will sound an alarm to remind the patient that there is a problem with the foot. Although the smart sock is a sensor wearable device, it does not need to be charged frequently. The built-in battery of each sock is fully charged and can be used for six months.
