The pace of technological development is getting faster and faster, and human beings are already in the information 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. Let's take a look at some of the latest sensor gizmos.

Miniature dental sensor

Want to lose weight, but can't open your legs, 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. It is often difficult to get the food.

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. Don't let it be small because of its small size. It is such a seemingly inconspicuous thing that it can fully 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, the sensor transmits radio frequency waves of different spectra according to different chemical substances 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 dynamically read and transmit the information received.

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 a 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, and 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 adhered 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 thin and soft material, which is extremely breathable and can be freely deformed. It can be worn continuously for one week. And will not cause any discomfort.

If a moving screen "grown" in the visible body of the person, you will certainly not be able to see more of the two eyes, people around you can also 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 home, the doctor can still remotely monitor the patient's physical condition with a computer or mobile phone. Can take timely response measures. This eagerly 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.

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. Innovate and perfect sensor functions. In the future, perhaps a fingernail can monitor your mental condition; a film shaped like a plaster can be placed on your body to record your exercise and energy consumption instead of your sports bracelet. The body is tailored to suit you the most appropriate diet.
