A sensor is a smart device that can detect and transmit information. Last year, China's Internet of Things industry has reached 365 billion yuan scale, the sensor is one of the largest demand, the most basic part. At present, China has a large gap with foreign countries in the design, processing and manufacturing of smart sensors, especially the high-end demand of more than 80% depends on imports. The size of the sensor business is generally small, the lack of competitive core technology, compared with foreign companies in the accuracy, production costs, chip size, etc. at a disadvantage. In spite of this, many foreign advanced technologies are worthy of reference from other countries.
According to the latest news, engineers at the University of California, Berkeley, using a flexible and flexible plastic, for the first time to create a thin electronic skin, also known as e-skin. This result is expected to allow robots have a more realistic feel. The most important element of this technology is the sensor principle used.
On the application side, the researchers believe the new e-skin, in addition to giving the robot a more subtle tactile sensation, can also be used to make facilities such as wallpaper, doubles as a touch screen display, dashboard laminate, etc., allowing the driver Need to wave the hand to adjust the control keys. Wang Chuan said: "It is also possible to design the e-skin as a bandage and wrap around the arm as a health monitor to continuously check blood pressure and pulse rate." At present, the team is designing an e-mask that responds to temperature, light and pressure, Skin sensor.
According to reports, MEMS sensors are system-in-package solutions with many advantages, such as high resolution, low power consumption and compact size, which are completely different from the semiconductor chips mainly utilizing the electrical properties of silicon. Insiders said, MEMS sensors to the mobile phone, MP3 / MP4 player, PDA or game console controller increases an intuitive man-machine interface, the people's movement and installation of the MEMS sensor devices interact.
The current consumer electronics manufacturers are looking for miniature, low-cost, low-voltage, low-power MEMS sensor. It is reported that the slim design is the development trend of battery-powered products such as mobile phones, MP3 and MP4 players and portable PC. Nowadays, multi-axis sensors have become a must-have for consumer electronics devices, enabling consumers to activate any function from any physical location. In portable products, there is no fixed MEMS sensor application reference frame. In addition, the life cycle of consumer electronics is getting shorter and shorter, which also requires product designers to make MEMS quickly and seamlessly integrated into the final application.
China Securities News, the invention of the electronic skin will undoubtedly contribute to the development of the sensor market, coupled with media reports, Apple Inc. recently showed the 3D sensor business of all ages, and Murata Manufacturing also announced the force MEMS sensor market, the sensor is expected to The field will usher in the tide of development.
