Innovative Applications Of Sensors

The pace of technological development is getting faster and faster, and human beings are already in the informational age. As one of the most important information acquisition technologies, sensor technology has been highly valued and has also been greatly developed. With the continuous innovation and breakthrough of technology, scientists have developed a variety of sensors, which are used in different fields such as daily life and medical care.

Miniature dental sensor

Did you ever want to lose weight, but can't control your mouth? It doesn't matter, the miniature tooth sensor can help you control your diet. Dieting is one of the most popular methods of weight loss for young people today, but often people not only fail to lose weight, but also accidentally fall into malnutrition. The hardest part of dieting is not controlling what you eat, but how much you should eat. The intake of food is often difficult to handle.

Now, the gospel of weight loss people is coming! Researchers at the Tufts University School of Engineering have developed a miniature dental sensor that is small and thin, and it is barely visible to people on the teeth. It is such a seemingly inconspicuous thing that can comprehensively monitor the type and amount of nutrients you consume, and accurately transmit data wirelessly to your mobile phone. As a result, people who want to lose weight can more accurately control the amount of food they eat. In addition, micro-teeth sensors can monitor people's stress levels and mental states by monitoring biochemical indicators such as stress hormones.

How does this miniature sensor work? The middle of the two square gold rings is fitted with a "bioreactive" layer that scans and identifies certain chemicals. When you eat food, the sensor transmits radio frequency waves of different spectra according to different chemical components in the food, representing specific information. So far, water, apple juice, salted soup, mouthwash and alcohol have been successfully tested. The researchers said that in theory they could modify the bioreactor of the sensor to allow it to identify more chemicals, and the sensor could be attached to the tooth after technical improvements, and can be dynamically read and transmitted information.

Weight-loss people can rely on micro-teeth sensors to monitor their diet and help them develop a balanced diet. The researchers pointed out that the sensor is still in the perfect stage, in the future it will not only know what you ate, how much you ate, but also how much energy you consumed. It is believed that in the near future, a fully functional, compact and convenient miniature dental sensor will become one of the most popular new inventions.

Electronic skin sensor

Researchers at the University of Tokyo in Japan are not far behind. They have developed an ultra-thin electronic skin sensor for the medical field. A miniature LED array is embedded in the electronic skin to display numbers, symbols and simple animations. It first uses the nano-electrode to measure the wearer's electrocardiogram and so on, and then displays it on the LED screen in real time. As long as water is sprayed on the bonding surface of the electronic skin to dissolve the polyvinyl alcohol (PVA) water-soluble polymer, the electronic skin can be closely attached to the body. The previous electronic skin has very poor air permeability, which is easy to cause discomfort and even inflammation of the wearer's skin. This new electronic skin is made of a thin and soft material, which is extremely breathable and can be freely deformed. It can be worn continuously for one week.  

If a moving screen "grown" in the visible body of the person, you will certainly be attracted, People around you can see and understand the wearer's physical condition. Therefore, this electronic skin sensor may be a health monitoring system for the elderly or the family. Once the wearer's body is abnormal, the sensor will reflect the situation on the screen in time. The researchers said that in the future, wireless communication devices will be added to the sensors, and the patient's data can be uploaded to the cloud. After the patient is discharged from the hospital, the doctor can still remotely monitor the patient's physical condition with a computer or mobile phone. This highly anticipated electronic skin sensor is believed to be ready for large-scale use in the near future and will greatly enhance the quality of human life.

Innovation never stops

There are many other sensors like this, some of them are in the development stage, and some have already been put into use, such as PM2.5 sensors for environmental monitoring, ultrasonic sensors for automatic robot navigation. With the in-depth research and wide application of wireless sensor networks, sensor applications have gradually penetrated into various fields of human life and have been highly valued by the industry.

At present, in the fields of medical care, environmental monitoring, wearable devices, automotive electronics, etc., the development of various sensors has become a common practice. The market demand for sensors can be said to be increasing. Scientists from all over the world are also struggling to catch up each other. In the future, perhaps a thing as big as a fingernail can monitor your mental condition; a film shaped like a plaster sticks on your body, you can record your exercise volume and body energy consumption instead of a sports bracelet. It can also design the most suitable diet for you based on your body.
