Self-help and Paradox of American Semiconductor

Image
There is no doubt that the technological competition between China and the United States will be the main axis of the global technology industry for a long time from the past to the future. And the chip occupies a unique position among them. All along, the Chinese media have been analyzing the impact of the US’s implementation of chip supply and chip sniping on China, and China’s possible response measures. In other words, we have been looking at what China should do. However, as a long-term competition mechanism, the impact of chip competition is by no means unilaterally released to China. The United States, standing at the other end of the field, is also desperate for a small chip. Overall, the semiconductor policy of the United States in the past ten years has been quite consistent. It can be summed up as follows: build factories in-house and engage in sniping outside to reconcile the contradiction between large companies and local employment. The motivation for these behaviors lies...

Tactile Sensor Arrays May Benefit Skin Monitoring

The manipulator can smooth grabbed soft fragile tofu, weight only 5 mg of small spiders, its motion sensor can be accurately captured, recently, Harbin Institute of Technology (Shenzhen) (hereinafter referred to as the "Harbin Institute of Technology (Shenzhen)") Hu Hong joint team, a professor at city university of Hong Kong Yang recruited professor bao team is put forward based on the piezoelectric thin film, tactile sensor array with row + column electrode structure, relevant results published in the journal of Advanced Science. The research provides a new strategy for tactile sensor design that is expected to benefit areas such as electronic skin, health monitoring, animal movement detection, and robotics.  "There are three main innovations in this research." According to Hu Hong, the multifunctional tactile sensor array can measure the pressure, bending radius and bending direction, and at the same time distinguish the mode of external stimulus in real-time, re...

What is Portable Ventilator System?

Image
  With the improvement of people’s living standards, obstructive sleep apnea syndrome is more and more common in clinical practice, and its incidence is high, which seriously affects the quality of life and life span of patients. At this point, the portable ventilator is particularly important. A portable ventilator requires the use of two pressure sensors to measure the pressure on both sides of the baffle in the ventilation pipe, accurately and quickly collect the pressure value and timely adjust the revolution of the fan to provide a comfortable air supply for snoring people, which is the most critical problem. A t  the same time, the application direction of the product in people with obstructive sleep apnea syndrome, so the volume of the product is required to be small, convenient to carry on business trips, and the price is also low. In the 16th century, the Flemish doctor Andreas Vesalius described ways to keep choking animals alive by inserting tubes into their trachea...

Top 10 Global Semiconductor Manufacturers in 2020

Image
Market research firm Gartner recently released its 2020 revenue forecast for the semiconductor industry. According to Gartner's forecast, the revenue scale of global semiconductor manufacturers in 2020 will reach the US $449.838 billion, a year-on-year growth of 7.3%. "At the beginning of 2020, the Coronavirus (Covid-19) pneumonia outbreak was thought to hurt all end device markets, but the actual impact was minimal," said Andrew Norwood, research vice president at Gartner. Certain segments of the auto, industrial and consumer markets have been hit by a drop in business and consumer spending. However, the market benefits from home isolation, which dramatically increases the time spent at home and online." "Server demand is strong as super-scale customers (accounting for more than 65% of server demand in 2020) rush to add capacity to cope with additional demand during the lock-in period in the first half of 2020. Besides, strong corporate and consumer demand for ...

Application Status of the Third Generation Semiconductor Material GaN Chips

Image
Near the end of the year, the fast charge market is extremely hot. In October 2020, Apple announced that iPhone12 series phones and all iPhone models sold on its official website would no longer come with chargers, which excited the whole fast charging market. Xiaomi 10, Huawei Mate 40, OPPO and Samsung's latest Android phones have all launched gallium nitride chargers, from 45W, 65W to 120W fast-charging products on the market. GaN charger is adopted by Apple, Samsung, Huawei, Xiaomi, OPPO and other top five mobile phone manufacturers in the world, which drives the whole fast charging industry to show a growth trend. According to Yole, a market-research firm, the biggest segment of the power GaN market is still power applications or quick charging of mobile phones. The market size will grow at a compound annual rate of 92% between 2018 and 2024. Among them, the GaN fast charging market between 2020 and 2023 growth rate will reach 55%. In an optimistic scenario, the gallium nitride...

The 5G Boom Promotes the Development of RF Devices

Image
In a wireless communication system, there integrated circuits are needed--fundamental frequency (BB), intermediate frequency (IF), and radiofrequency (RF), which convert and transmit the received signal to realize the communication function. Generally speaking, RF is responsible for receiving and transmitting high-frequency signals, the fundamental frequency is responsible for signal processing and storage, etc. The intermediate frequency is the bridge between RF and BB so that the signal can be smoothly converted between high-frequency signals and fundamental frequency signals. RF devices, the key components of various wireless communication equipment such as mobile phones, are mainly responsible for generating, sending, receiving, and processing high-frequency electromagnetic waves. Unlike AD/DA, which converts analog and binary digital signals, RF technology amplifies weak low-frequency analog signals into high-frequency electromagnetic waves to transmit information and filters the ...

New Spectral Sensing Technology for Detection of COVID-19

Image
General Description of AS7341L AS7341L is a 10-channel spectrometer for spectral identification and analytic applications used in mobile devices. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photodiode without filter ("clear"). The NIR channel in combination with the other VIS channels may provide information about special characteristics of analytes (e.g. Lateral Flow Tests).   The device can also be synchronized to external signals via pin GPIO.                                                  Ams Semiconductor AS7341L Spectral Sensor Solution AS7341L integrates filters i...
