High-precision sensor technology paves the way for medical care

Health care is the most promising application area for wearable devices (followed by fitness and entertainment), and there are agencies that predict that wearable technology accounts for at least 50% of wearable devices in healthcare. Wearable devices will bring about a revolution in the medical device industry (miniature-portability-wearable), which can not only monitor human health indicators such as blood glucose, blood pressure, heart rate, oxygen content, body temperature, and respiratory frequency, but also at any time. Can also be used for the treatment of various diseases, such as iontophoretic patches can treat headaches, smart glasses can help people with Alzheimer's disease to awaken people and things that are easy to forget.

In this regard, Deng Dengfeng, a senior product manager of the mixed-signal and RF product line of Hangzhou Silan Microelectronics Co., Ltd., believes that the medical properties of the wearable devices are the general trend, and consumers are increasingly concerned about their own health. Most current wearable devices only achieve pulse function, and body temperature, blood pressure, and blood glucose are three urgently needed directions. Body temperature testing is necessary for infant monitoring and pregnancy monitoring. Blood pressure testing and blood glucose measurement are very welcome functions for most middle-aged and elderly consumers.

Wearable devices as a kind of portable devices and electronic products with certain medical attributes may move toward the direction of portable medical devices. Large-scale medical devices are potentially hazardous during treatment and testing, and they are used daily. The electronic radiation of mobile devices can also be concerned by healthy users from time to time. Therefore, the medical characteristics of the wearable device and the characteristics of wearable devices need to be clearly defined in terms of possible radiation.

Xu Youjin, the founder of Desai Group Micron Studio, believes: "This year's launch of Desai's second-generation smartband Fitband will lead the world in sleep improvement in the next year or two. We will use our unique multi-dimensional health monitoring in health monitoring. The advantages of the algorithm.At the same time, we will dig deeper into the subdivided areas of sleep health and make medical-level smart bracelet products. We will invest in theoretical algorithms, manufacturing processes, human-computer interaction, and third-party services. Continuous R&D and productization.” Desai first established its own product features and strengths in smart wearable devices.

Xu Youjin made a commitment statement: "We launched the Fitband smart bracelet, mainly through the Bluetooth 4.0 BLE transmission, low power consumption, radiation is also very low, and not a long link, is connected on demand. Data will be stored on the server, At the same time, it is presented to users on the mobile phone App. In addition, the main control chip that we use, when working, has an average power consumption that is basically at the Naan level, so it is basically suitable for all people.”

Tang Dekai gave advice on the possible radiation of medical grade wearable devices: “Products with electronic devices must have radiation, of course, strictly speaking, it can be tested to see whether this radiation exceeds the accepted human safety standards. It is not suitable for wearables. The person of the equipment is not good at all, it should be considered according to the characteristics of each smart wearable device or the segmentation of the population. For example, a person with a pacemaker is generally not suitable for a charged smart wearable device.

The hot start of the domestic wearable market has provided tremendous room for development and good opportunities for domestic and international MEMS sensor production supply chains. Tang Dekai said: "The smart wearable market is booming, and potential market demand will stimulate and promote more companies to upgrade or develop EMMS sensors suitable for smart wearable devices. The driving force of commercial value is enormous. For commercial interests, domestic EMMS sensor manufacturers will invest in improving the technological level of EMMS sensors.The innovation of EMMS has a decisive influence on smart wearable devices. It can be said that EMMS innovation and breakthrough will bring true wearable devices to the real world. spring."

YAN Yanhui, ADI's Asia-Pacific micro-electromechanical product market and application manager, believes that wearable devices will be very rich in the future. Watches and wristbands can be found everywhere today. They may appear in the form of decorations, such as necklaces and rings. There are headphones, even a button. The functions will also become more and more powerful. In the short term, medical and health monitoring will continue to be the main trend. The most important requirement for sensors is accuracy, volume, and power consumption.

“The domestic MEMS sensors have gaps in the entire industry chain, including design, technology, packaging and testing. The gap requires the participation of all participating companies to learn and accumulate, and there are always many foreign companies to do the reference. It will be much faster. As long as we continue to concentrate on doing so, I believe soon In the future, the domestic sensor industry will also occupy a large market share.The domestic sensor industry still has its own advantages, for example, the long life cycle of the domestic sensor industry, as long as the meticulous efforts to do, will solve all technical problems; The support for the development of integrated circuits has continued to increase, and related companies can do nothing.” Deng Dengfeng is full of confidence in the prospect of domestic MEMS sensors.

The breakthrough direction of MEMS sensors with higher precision, lower power consumption and smaller volume is clear and clear. In terms of the wearable device industry, it is necessary to consider how to make greater value in terms of practicality and functionality. Only functional improvement can make the wearable device market expand and become a necessity product for users. Because the red fire in the wearable device market has provided a new application direction and field for MEMS sensors, the next step is to strengthen the functionality of the wearable products and promote the development direction of the smart wearable industry to be achieved through the breakthrough of MEMS sensing devices. The function of the wearable device is embodied in two directions of extension of the human organs and enhancement of the medical attributes. Based on the monitoring of the original accurate data provided by the high-precision MEMS sensing device provided by the semiconductor manufacturer, a more optimized algorithm can be applied when the device is worn. Maximize the functionality of the wearable device.
