Continue to break through new sensors that were developed in March

[China Instrument Network Instrument Development] With the continuous development of the Internet of Things, the requirements for sensors are also constantly improving. According to the “2018-2022 Smart Sensor Industry In-Depth Survey and Investment Prospect Forecast Report” released by the China Investment Advisor, it is expected that smart sensors will reach US$37.85 billion in 2019. Driven by the huge market, major R&D institutions are continuously demanding breakthroughs and have developed new types of sensors.

Quantum sensor capable of measuring nitrogen atom size of micro magnetic field

Fraunhofer uses a new quantum sensor developed by the Institute of Solid State Physics (IAF) and the Maple Solids Institute. Researchers have produced ultra-pure single-crystal diamond crystals by implanting a single nitrogen atom, or creating a fine diamond tip after nitrogen is added in the final step. The introduced nitrogen atoms and neighboring vacancies in the lattice are the actual sensors.

The sensor is only nitrogen-sized and can accurately measure small magnetic fields on hard disks that are only 10 to 20 nanometers. In addition, the sensor can determine its strength and its application potential is surprising. According to IAF experts, this quantum sensor can also be used to measure many weak magnetic fields, including brain waves.

Novel graphene-based nano-roll sensor capable of mimicking dog nose detection gas

Chinese researchers have been inspired by the nose of dogs. There are millions of capillaries in the nose of a dog and the surface area is large, which helps the dog to smell a very low concentration of odors. The researchers chose a graphite with a large surface area and high temperature stability and durability. Alkenyl nano roll production gas sensor.

The new graphene sensor production process is simple and efficient, and is expected to be prepared on a large scale. The research team plans to use this material in the future to develop gas sensors that can be used to detect toxic gases, as well as medical equipment such as nitric oxide exhalation detectors.

Leakage sensor to reduce leakage in water supply network

An enterprise in Longzheng Intelligent Sensor Town, Changzhou, Jiangsu Province, successfully developed a “listening leak” sensor. A noise sensor is installed on the pipeline every 200 meters or so. It can be installed by using an inspection or a well in an underground pipe network. After the missing point information is detected, it can be transmitted not only to the computer client of the monitoring system, but also directly to the mobile phone terminal for convenient and timely processing.

The “listen to leak” sensor can “listen” for up to 300 meters, and has performed well in the trial run of several universities. According to reports, the "artifacts" need to be heard and the cost is only one-third of the UK's imported equipment, each about 8,000 yuan.

Low-cost infrared sensor for laser radar

A low-cost infrared sensor developed by Ben-Gurion University, a famous Israeli research university, can create the world's thinnest night-vision goggles. It can be assembled in front of ordinary glasses or telescopes to transform them into infrared devices. Thin films are fabricated on conventional visible light sensors, making them infrared sensors.

This technology will bring low-cost infrared sensors that can be applied on a large scale to help auto-driving cars 'see' farther and clearer, and can also be applied to LiDAR (Lidar) sensors perceived in vehicle environments.

The highest resolution 35mm sensor

ON Semiconductor Announces New 43-megapixel (MP) Charge-coupled Device (CCD) Image Sensor with Optical Format of Convenient 35 mm, High Resolution, High Quality and Uniformity over a Wide Range of Exposure Times Degree of image capture.

The sensor extensions are used in applications that require stringent high-resolution industrial imaging for applications that require extremely high resolution image capture and excellent image uniformity, such as high-definition (HD) and ultra-high-definition (UHD) flat panel displays for end-of-line inspections.
