By 2020, there will be 30 billion wireless sensor nodes installed in the world, and the number of sensors may reach trillions in the next decade. In China, with the rapid development of industries such as automotive electronics, new digital consumer electronics and medical electronics, the demand for sensors in the domestic market is showing a rapid growth trend. According to the forecast of China Electronics and Information Industry Development Research Institute, the domestic sensor market will grow 31% year-on-year in the next five years. The sensor market in the fields of automobile, logistics, mining exploration, coal mine safety supervision, security, and RFID tag cards has grown rapidly. Among them, consumer products and the automotive industry have the largest demand for sensors.
In this context, the smart sensor technology represented by MEMS has been rapidly developed. Compared with traditional sensor technology, MEMS is small in size, light in weight, low in cost, low in energy consumption, high in reliability, easy to mass-produce, and high in intelligence. It is now in a state of rapid development. As the world's leading provider of data conversion and signal processing technologies, ADI has focused on developing the core technologies of MEMS sensors to suit the needs of different markets. Mr. Zhao Yanhui, Marketing and Application Manager of ADI's Asia-Pacific MEMS products, said.
MEMS smart sensors popularize ADI from three major areas
In China, consumers have gradually shifted to the need for higher levels of security, from the initial demand for basic vehicle functions. Third-party research reports show that the growth rate of safety-based automotive semiconductor components is at the forefront of automotive electronics. Mr. Zhao Yanhui also added that due to the increasing awareness of consumer safety, the market demand for high-performance digital signal processors such as advanced driver assistance systems based on radar, visual signal processing, more accurate MEMS accelerometers and gyroscopes. non-stop upgradin.
Mr. Zhao Yanhui gave a brief introduction to ADI's representative products in the field of automotive active safety technology. He said that ADI's new generation of airbag acceleration sensors ADXL185/ADXL189/ADXL188/ADXL288 and angular speeds for ESC and Rollover/Roll stability The sensor ADXRS800 integrates numerous system functions such as self-test, signal bandwidth setting, threshold triggering, excellent resistance to vibration, and more. ADI has delivered more than 500 million MEMS sensors to date, with nearly 20 years of experience in collision sensor design and related knowledge accumulation and technology.
Wearable medical deviceWith the rise of the mobile medical boom, wearable applications are no longer at the level of “being talked aboutâ€. At present, there are more and more actual realities in the fields of signal detection products, sports equipment and consumer products. The emergence of commercial products, this year will be the growth period of the market, and will be a breakthrough growth, and a large number of related products.
According to the current market development trend, Mr. Zhao Yanhui said that ADI will be more actively involved in the field of wearable medical electronics, continue to strengthen the industry-leading investment in MEMS technology and analog mixed-signal processing chips, and continue to increase the development of system solutions, including hardware platforms. And the development of the corresponding software algorithms and the investment of technicians in the relevant system applications, launched a series of semiconductor products and reference designs suitable for wearable medical needs. More importantly, ADI has established a dedicated technical application and development team around vital sign signals and motion monitoring applications to provide solutions and support beyond the chip level. Recently, Withings announced its latest wearable device "WithingsPulse", which uses the ADXL362 from Analog Devices. MEMS smart sensors popularize ADI from three major areas
Industrial intelligence requires two-way interaction. The development of network communication and intelligent sensing technology will promote the intelligent development of industrial control. Network communication technology can integrate industrial control into a system, which can easily connect discrete subsystems and nodes into large systems. More and more industrial control systems are connected and more networked and intelligent. For the complex field and specific conditions of industrial applications, high temperature, high reliability, and devices that require isolation also require more new technologies to support.
Mr. Zhao Yanhui also stressed that ADI's MEMS products not only focus on basic motion detection or novel features, but also consider extreme working conditions. For example, in the oil logging industry, it requires sensors to maintain key characteristics such as sensitivity, noise and zero accuracy under extreme conditions such as shock, vibration and high temperature. These MEMS sensors provide valuable and critical system performance improvements that provide logging or extraction efficiency, reduced system downtime, and other significant benefits.
