As the field of sensor applications continues to expand, the sensor market will continue to grow at a high rate. Looking back at the current sensor market, which new products are well-deserved "black technology"? Next, the sensing market will see how to subvert the three new products, let us wait and see.
As the most basic hardware in the era of intelligent sensing, the intelligent process is accelerating, and any connected intelligent terminal nodes are inseparable from sensors. As the field of sensor applications continues to expand, the sensor market will maintain rapid growth, especially wearable devices, automotive electronics, medical, Internet of Things, etc. will become the main growth point of sensors. Then, looking back on the past, what other "black technology" products that ignite the eye in the sensor market?
1. Molecular sensor
In the past, although there have been techniques for using chemicals in "invisible inks" that require encryption, it has been difficult to ensure that hidden information is not read without authorization. In response to this situation, David Margulis of the Weizmann Institute of Science in Israel and his research team have developed a fluorescent molecular sensor that can distinguish different chemicals by generating specific fluorescence emission spectra. Considering recent concerns about global electronic surveillance, this sensor provides a means of security that bypasses electronic communication systems.
2. Wireless sensor
In recent years, fitness trackers have become a more popular wearable technology product. However, engineers at the University of California at Berkeley took this concept one step further and developed tiny wireless sensors to detect health in the human body. It is reported that these devices have been reduced to one cubic millimeter and only about one grain of dust, called "neural dust." These sensors can be implanted in the body of a person where they can detect tissue, muscle and nerves in real time.
3. Bioluminescence sensor
Bioluminescence sensors are actually a new type of research method, which was invented by a group of scientists at Vanderbilt University in the United States by genetically modifying luciferase. According to the researchers, this new sensor can be used to track the internal interactions of large neural networks in the brain.
4. Artificial hair sensor
For humans, skin is not only a barrier to protect us from dust and bacteria, but also a medium for us to feel the changes in the external environment. As researchers develop robotics further, they are also working hard to create the same functionality as real skin for robots. He Xiaodong, professor of materials science at Harbin Institute of Technology, China, and his colleagues have innovated in this area. The new technology they developed can mimic the fine hair of the human body and transmit sensory information to the robot. The researchers used 30 micron thin wires instead of hair, and embedded a row of tiny wires in the silicone rubber, and the role of this row of wires is to bring outside information to artificial skin. The results of this research can be used to sense prosthetics or corresponding health care equipment.
5. Composite touch sensor
At present, most robotic touch sensors only have load cells, so they can only detect the hardness and texture of the object, which makes the robot's accuracy in identifying foreign objects very low. But if combined with traditional force sensors, the composite touch sensor helps the robot recognize the composition of the object. It is this principle that Georgia Tech's experts showcased the "skin" that they designed for robots to produce heat from conductive and non-conductive fabrics and thermistors.
6. Air sensor
TZOA has introduced a new air sensor. It is understood that this is a sensor that collects air quality information, including the type and quantity of particles and whether they contain harmful chemicals. And the device also protects the fetus and children from contaminants that affect brain development. In the future, the company plans to sell equipment for outdoor pollution in China and India, as well as equipment for indoor pollution in the United States. TZOA is also developing an asthma device that helps determine the triggering factors of asthma attacks.
7. Promote sleep "Sense" sensor
According to reports, James of London in England invented a sleep sensor called "Sense". It is understood that the "Sense" sensor can automatically adjust the light according to the owner's control, control the heating, and even play soothing music to promote human sleep, and adjust the environment to the most comfortable state during sleep. It also monitors sound, lighting, temperature, humidity, and air quality to score the user's sleep every night.
8. EMG sensor
Sensors have always played an important role in the health care arena because they are at the forefront of collecting data. The myoelectric sensor independently developed by Shanghai Haodian is a kind of charge sensor with high sampling rate, strong anti-interference ability and good filtering effect. The sensor has been successfully applied in rehabilitation medicine and bionic prosthetics, and will be extended to the VR/AR, physical fitness, and human bones in the future.
9. Temperature sensor
SirenCare, 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.
10. Skin sensor
According to reports, Japanese researchers have recently invented an inexpensive integrated sensor like a band-aid. This band-aid integrated sensor is a flexible device that can be attached to the body at will, which can monitor human activity, heart rate and UV intensity, and can be used in health management and Internet of Things. The stickable skin sensor is printed on a thin plastic film using the newly developed printing technology. Compared with the previous semiconductor sensor manufacturing technology, the cost is low, and the convenience and low cost are taken into consideration.
to sum up
At present, sensors have been widely used in various fields of social development and human life, such as industrial automation, agricultural modern ratio, aerospace technology, military engineering, robotics, resource development, ocean exploration, environmental monitoring, security, medical diagnosis, transportation. Transportation, household appliances, etc. Among them, pressure sensors, temperature sensors, ultrasonic sensors, flow sensors, and level sensors have shown the characteristics of mature markets. According to the statistics of the National Bureau of Statistics, as the impact of the financial crisis has slowly declined, the domestic sensor market sales have recovered more than 10%. In 2016-2021, the sensor market will see a large-scale growth due to strong investment in IoT investment and other application areas.
