The sensor is a detection device widely used in industrial production, environmental protection, biomedical, resource detection and other fields, and plays an irreplaceable role in promoting economic development and social progress. At the beginning of 2017, there were all kinds of news about new breakthroughs in sensors. Among them, there are new biosensors for real-time detection, smart phones equipped with small-scale molecular spectroscopic sensors, and Finland's successful development of the world's first hyperspectral mobile sensor. Collect and collate the development of the five major sensors in the near future so that everyone can have a more comprehensive understanding of the latest technologies.
Breakthrough 1: Finland successfully developed the world's first hyperspectral mobile sensor
The Finnish VTT National Technology Research Center successfully developed the world's first hyperspectral mobile device by converting an iPhone camera into a new optical sensor, which will bring new prospects for low-cost hyperspectral imaging consumer applications, such as consumers. Ability to use a mobile phone for food quality testing or health monitoring.
Spectral imaging is widely used for various object sensing and material property analysis. Hyperspectral imaging performs spectral analysis of each pixel in the image for a wide range of measurements. Hyperspectral cameras have been used for medical, industrial, space and environmental sensing in harsh environmental conditions, but are expensive. VTT developed a hyperspectral mobile device that combines smart sensors with the Internet by integrating an adjustable tiny MEMS (micro-optical electromechanical system) filter with the iPhone's camera lens and synchronizing its adjustment functions with the camera's image capture system. It makes it possible to develop new mobile applications using cost-effective optical MEMS spectroscopy, such as consumer applications such as environmental observations, health monitoring and food analysis using vehicles and drones.
Breakthrough 2: The world's first smart phone with a small-scale molecular spectrum sensor released
Recently, Changhong released the world's first molecular identification mobile phone, Changhong H2, which is the world's first smart phone equipped with a small-scale molecular spectrum sensor, which can realize the sugar and water of fruits and vegetables, the authenticity of medicines, the age of skin, the quality of alcohol, etc. Detection, becoming a personalized health management integrated terminal that is carried around.
It is understood that Changhong integrates the capabilities and precision of laboratory-level spectrometers into mobile phones that people can carry and use on a daily basis, effectively improving the quality of daily life of users. For example, it is also very helpful in detecting the safety of food. The H2 mobile phone sends a command to the miniaturized high-resolution near-infrared spectroscopy sensor to perform "near-infrared absorption spectroscopy" data acquisition on the measured object, and transmits the spectral data to The cloud platform analyzes, calculates, and processes, and obtains qualitative and quantitative analysis results. The mobile phone presents the results of data and graphics to the user, and gives corresponding suggestions and recommendations to the user. The H2 mobile phone can directly identify the molecules of the substance. Attributes. This will identify the safety of food and ensure safety.
Breakthrough 3: Nanosensors put atomic level drugs into cells
The operation of nano-sensors has aroused people's attention, and can complete various observation, characterization and manipulation operations that cannot be realized by traditional robots at a very small scale, which is called “in every possible wayâ€. By changing the nanotechnology, atomic-level drugs can be introduced into cells to observe the effects of these drugs on cells.
The nano-operated robot features position detection sensors for automatic programmable motion and a wide range of powerful add-on modules. Compared with traditional robots, nano-manipulating robots are characterized by super-sensitive, ultra-high precision, and can perform various observation, characterization and manipulation operations that cannot be realized by traditional robots at a very small scale, which is called “in every possible wayâ€.
Breakthrough 4: New optical biosensors can identify infectious diseases in seconds
Recently, Russian scientists have developed a new laser technology for the manufacture of novel optical biosensors that recognize infectious diseases in seconds. The device uses infrared light to display harmful bacteria and viruses, and can be widely used in large transportation hubs such as airports where it is necessary to continuously monitor a large number of passengers.
This rapid analysis may be widely used in large transportation hubs, such as airports, where there is a constant need for health monitoring of circulating passengers. Currently, this is achieved by tracking the body temperature with a thermal imaging camera. A fever passenger may be a potential source of infection. In this case, a clear analysis is necessary to identify whether the person is actually ill or what other reason. It takes several days to investigate biological materials using existing methods, such as the polymerase chain reaction method. In contrast, this new technology can immediately provide the results of the test.
Breakthrough 5: The world's first wafer-level sensor chip or pick-up spectrometer application revolution
On January 17, 2017, leading high-performance sensor solutions and analog IC supplier Amys Semiconductor (amsAG) announced the world's first cost-effective multi-channel spectral on-chip sensor solution for new consumer and industrial applications A generation of spectrum analyzers opened the way.
Multispectral sensors use new manufacturing techniques to make nano-optical interference filters adhere directly to CMOS silicon wafers with extreme precision. The sensor's interference filter technology is extremely accurate and stable, independent of time and temperature, and is smaller and more cost effective than components commonly used in today's spectrum analysis instruments.
