[Electronic sensor and other parts of the vehicle were recalled] Elf on June 11 news, it is reported that Apple's blood pressure monitoring system includes pressure sensors, expandable components, and expansion components of the drive in three parts. In other words, Apple's new patent is still taking the principle of traditional blood pressure measurement, only to achieve miniaturization. What are some important things to note about today's sensor industry?
His motor sensor breaks the 100% import spell with higher accuracy and 7 patents have taken 40 million orders
With the development of Tesla, electric vehicles have gradually been recognized by consumers. Traditional car manufacturers like Toyota and Volkswagen have also manufactured hybrid cars. All automotive motors are inseparable from the sensors. Liu Jia, as a co-founder, has established the “Insert Sensing†and provides all-electric motor sensors.
At present, the mainstream motor sensors on the domestic and foreign markets are traditional rotary transformers. The worst-case accuracy of high-speed rotation will reach 26°, and the 钧-inclined sensor can guarantee the accuracy of 1° at full-speed state. The smaller the degree, the more precise the motor can be controlled at high speeds. This technology is still blank in the market.
At present, "Emerging Sensing" has already signed contracts with U.S. and U.K. first-tier suppliers. It has signed a contract of 40 million and another 50 million contracts are in the process of being signed because the auto industry determines the specific price based on the final sales volume. , Its product unit price is between 100~300 yuan.
Dalian Institute of Materials and Materials, etc. made progress in the study of perovskite single crystal digital image sensors
Recently, Liu Shengzhong, a research fellow of the Thin Film Silicon Solar Cell Research Group of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Yang Zhou and Dr. Liu Yucheng, associate professors of Shaanxi Normal University, have made new progress in the research of perovskite single crystal digital image sensors. Related research results are Published on Advanced Materials.
As a super material for solar cell applications, the perovskite CH3NH3PbX3 (MAPbX3, X=Cl, Br, I) also shows an important application prospect in the field of optoelectronics. Compared to polycrystalline films, perovskite single crystals have better optoelectronic properties. The team first developed a low-temperature gradient crystallization method (LTGC) to grow high-quality perovskite CH3NH3PbBr3 single crystals through fine-tuning crystal nucleation and growth processes, resulting in ultra-low defect state densities and greatly improved carriers. Migration rate and carrier migration lifetime. In addition, researchers successfully used a high-quality single crystal design to produce a large-area (≈1300mm2) imaging assembly consisting of a 729-pixel sensor array. The device has a very fast response speed, excellent light responsivity, high-resolution imaging capabilities, and good stability. It is the first high-performance digital image sensor based on large-size single-crystal perovskites currently researched and reported. For the use of perovskite single crystal materials design and development of new optoelectronic devices provide new ideas.
Hanwei Science and Technology: Some Products of Xiaomi Ecological Chain Use Company's High Quality Sensors
Hanwei Technology introduced on the interactive platform on Monday that the high-quality sensor produced by the company continues to enjoy a high coverage rate in the downstream applications, and it has closely cooperated with related ecological chain companies.
The company revealed that some products in Xiaomi's ecological chain, such as gas and air purification, use the company's high-quality sensors, including flexible pressure sensors used in products such as balance cars, and sensor products manufactured by the company. The company will continue in the future. Increase the investment in sensors, expand more types of sensors, and conduct more in-depth cooperation with downstream applications.
Sensor memory hidden part of Alfa and other models were recalled
Recently, Toyota Motor (China) Investment Co., Ltd. has filed a recall plan with the AQSIQ. From March 31, 2018, it will recall some of the imports produced from May 20, 2015 to January 12, 2016. -2016 Lexus NX, RX and some 2015 models of the Toyota Alpha series. According to the company’s statistics, a total of 22,648 vehicles were involved in mainland China.
In the airbag control system of some vehicles within the recall range, due to improper production conditions of the IC chip in the acceleration sensor or pressure sensor, there may be a break in the IC, which may cause the airbag warning light to illuminate and the airbag to fail to deploy normally. There are security risks.
Apple acquires new patent to measure blood pressure through sensors on wristwatch
Recently, according to foreign media reports, Apple obtained a patent that allows the device to measure blood pressure. From the patent map, this device is most likely a smart watch.
It is reported that Apple's blood pressure monitoring system includes three parts: a pressure sensor, an expandable component, and an expansion component driver. In other words, Apple's new patent is still taking the principle of traditional blood pressure measurement, only to achieve miniaturization.
According to Apple's patent, their device plans to install a sensor to measure the pressure of blood flowing through the user's arm or leg. There is also an "actuator" to measure how much pressure is needed to get good readings, and does not discomfort the user's arm at all.
Australian National University develops miniature optical structure nanosensors
A team of researchers at the Australian National University (ANU) Nanotechnology Research Laboratory has developed a miniature optical structure of nanosensors that are even 1/50th the thickness of human hair. Integrating them into wearable devices can help doctors detect and Manage chronic conditions in patients. Research papers were published in the "AdvancedMaterials" journal published on June 4.
