In recent years, with the wide application of IoT, data acquisition combined with wireless transmission has become a favorable partner, greatly improving people's monitoring of data changes. Instantly, the value that the sensor brings is further magnified. Combined with innovative sign signal acquisition and processing technologies, as well as the development of peripheral technologies in sensor-related fields such as power supply technology and new communication technologies, a number of medical health emerging products and service models with innovative sensor technologies as the core have been created to be wearable. The representative mobile medical market is just like this. Thinking behind the initial growth of China Mobile's medical market: the “multi-facetedness†of medical data In recent years, the mobile medical market has continued to grow, especially in China's mobile medical market, which has maintained a high growth rate of more than two digits. However, returning to the industry's insights after high growth, the medical industry is actually a data-intensive industry. Compared with traditional medical care, mobile medical care is more dependent on data. It can be said that the essence of mobile medical care is the management of user medical data. On the one hand, the data collected in the medical and health field applications are diverse and can be roughly classified into the following types: ï¬ Physiological biological data collection, which is also the most commonly used field of medical sensors, including human body vitals data, physiological markers, and biochemical, bioelectricity, thermal, optical and other changes due to biological reactions; ï¬ Environmental data collection that may affect health; ï¬ Physical data such as motion, posture, and pressure may be image health and safety status; ï¬ Whether food intake meets health standards, and data collection of food ingredient freshness. Figure 1. Types of data acquisition for sensors in the health care field (source: Eggshell Institute). On the other hand, the high requirements for data accuracy have become a major obstacle to the entry of many innovative medical sensing technologies into the medical market. It can be said that as the entrance to medical health data, the accuracy of data is the greatest application value of medical sensing technology. Inventory: ADI heavyweight mobile medical sign data monitoring program As the industry leader in the global market analysis of the 2017 Mobile Medical and Fitness Sensors Global Market Analysis Report, ADI has achieved comprehensive monitoring technology coverage at the front end of the signal chain, such as photoelectric, impedance, physiological potential, body temperature, and exercise. And the environment, etc.: Figure 2. A diagram summarizing the ADI mobile medical omnipotent monitoring program. ï¬ Photoelectric measurement: In the signal monitoring technology of the sign, the photoelectric measurement method is actually a very hot technology in recent years, which can be used to measure heart rate, blood oxygen content and blood pressure. And why is it so hot in the past few years, because of the breakthrough of fine structure and optical design technology, according to ADI, the industry has spent 1~ on how to suppress internal reflected light and external ambient light, that is, to reduce interference. It took 2 years to get it. In fact, ADI's ADPD series of sensors and signal processing solutions are being designed and used by almost all major brand customers in the photoelectric measurement of physiological signs. For example, the representative ADPD174 can be said to be a highly integrated photoelectric measurement on the market. Modules, integrated photodiodes, LEDs, analog front-end acquisition AFE, LED drivers and ambient light suppression, combined with small size, low power consumption (due to its flexible configuration), not only for professional medical diagnostic products It can also be applied to the collection of consumer-related product-related signs. Figure 3. Process and design are the key to optoelectronic measurement technology. ADI has accumulated many years in the field of optoelectronics. ï¬ Physiology Potential & Impedance: Currently, the most mature application of physiological potential & impedance measurement is to measure breathing and electrocardiogram (ECG). In terms of ECG, ADI actually provides both single-lead and multi-lead solutions. The single-lead ADI heart rate monitor analog front end AD8233 with cost-effective advantages has been characterized by its ultra-small size and ultra-low power consumption. It is valued and applied by many ECG bracelets and ECG chest stickers manufacturers. And the corresponding single-lead solution, ADI's other highly integrated ADAS1000 integrated multi-lead ECG, breathing and pacemaker detection and other functions in one, is the preferred solution for high-performance diagnostic-grade ECG monitoring; Figure 4. From single-lead for mobile healthcare to multi-lead for professional healthcare, ADI introduces a system-level ECG solution. Second, another important application of physiological potential & impedance measurement is body fat (BMI) analysis and monitoring of emotions. On the one hand, the PPG signal is monitored by impedance measurement technology, and the pressure is measured. On the other hand, combined with the photoelectric measurement method, the heart rate variability is measured, and the two are combined by the algorithm to analyze the deeper emotional stress monitoring product. Figure 5. Emotional stress monitoring has become a new direction for mobile healthcare, and ADI provides modules to help customers TIme to market.
