Advantages and disadvantages of Bluetooth, WiFi, Zigbee, which is more suitable for IoT?
At this stage, the aging process in the world is accelerating, promoting the continuous increase in demand for elderly care services and the expansion of the scale of the elderly care service industry. In 2018, the number of people over 65 accounted for 9% of the world's population, and the total number of people over 85 years old increased rapidly. The large scale of the elderly group has promoted the great requirements for products and services related to healthy old age.
According to the National Bureau of Statistics, by the end of 2019, the number of people aged 65 and above in China exceeded 176 million, accounting for 12.6% of the total population. According to the survey, in 2019, the scale of China's smart elderly care industry will be nearly 3.2 trillion yuan, with a compound growth rate of more than 18%, and it is estimated that the industrial scale will exceed 4 trillion yuan by 2020. It can be seen that smart elderly care has become the development direction of the future pension industry. Moreover, sensors are indispensable in various application scenarios of smart elderly care, and they have brought effective basic support technology guarantee for the smart elderly care industry.
The smart elderly care developed by applying computer network technology, 5G, Internet of Things, cloud computing, and artificial intelligence technology has promoted the development of the elderly care industry. The smart elderly care industry will become the main battlefield of consumption transformation and upgrading, and it is also the core of the innovative application of big data, which will create and open up another huge market. According to the statistical analysis of industry authoritative institutions, in the next 5 years, within China's smart elderly care industry, the market shares of sensors, smart wearables, home intelligent terminals and service robots and other intelligent hardware products can reach 80,000~10 trillion yuan, integrating a variety of new platform architecture and related industries, especially the integration and innovation of service methods, all industries will reach a market capacity of 30 trillion yuan, enough to support the industrial structure adjustment, transformation and development of the domestic service industry, and provide room for future imagination of China's real economy.
Smart elderly care promotes the combination of elderly care and modern information technology
The birth of smart elderly care provides a direction for the integration and development of elderly care services and information technology. Guo Yuansheng said in an interview with reporters that smart old-age care pays more attention to wisdom, pays more attention to the spiritual life of the elderly, and pays more attention to the coordination of several subjects (the elderly, families, communities, pension institutions, etc.). Also, smart old-age care is more manifested in the level of spiritual services, so that the elderly can achieve "my health I know, my health I manage" and prevent serious diseases in advance, and control the body's indicators within the range of health parameters to enhance their own immunity.
In China, in addition to a small number of public pension institutions and relatively supporting facilities, the main strategies for facing an aging society are "home care, community help, and science and technology to help the elderly". Smart elderly care requires three main service capabilities: first, the management function of home equipment and facilities; Second, the monitoring and management function of chronic diseases in the elderly group; The third is the personal emotional escort function required for the spiritual comfort of the elderly. "It is not difficult to see that the facilities and equipment such as smart home products, smart home intelligent supporting and control platforms, wearable devices, home smart terminals and service robots necessary in the future home are indispensable." Guo Yuansheng said.
Whether it is a physical quantity of sound, light, electricity, magnetism, force, temperature and other sensors, or chemical quantity gas composition, organic components, molecular weight size and concentration of sensors, and biomass cells, viruses, bioelectricity and other sensors will have a certain degree of innovation demand, and have much more market development opportunities.
Smart elderly care needs to achieve functional upgrades at the traditional level of food, clothing, housing and transportation, and more humanized and age-appropriate human-computer interaction technology. This depends on more convenient and accurate sensors, such as image sensors and related image recognition technologies and processing algorithms, audio signal acquisition and processing modules, EEG signals and EMG signal sensors. At present, empty nesters account for a certain proportion, safety is a major requirement, need a large number of monitoring air quality safety, fire, gas, anti-theft, anti-abnormal entry and other aspects of environmental monitoring related sensors, and monitoring the elderly fall, long-term abnormal lying and sitting sensors.
In the smart devices that detect the physiological condition of the elderly and the smart devices that monitor the exercise status of the elderly, MEMS sensors with small size, low power consumption and low cost will be very useful.
Every year, about 500,000 elderly people disappear in China, and at least 1,370 people are lost every day, and dementia and lack of care have become the main causes of elderly disappearance. Sensor fusion positioning can monitor the physical condition and specific location of the elderly in real time, which can effectively prevent and better solve the problem of the elderly getting lost.
Sensor companies seize new opportunities of smart elderly care industry
For Chinese sensor companies, smart elderly care hardware equipment and service platforms are bound to widely use various physical, chemical and biological sensors, thus providing an incremental market for sensor companies. In the future, smart elderly care will require a large number of IoT equipment, which must meet the characteristics of the elderly and user habits, so they also have requirements for sensor companies.
In the process of sensor enterprises intervening in the smart elderly care industry, it is necessary to create a collaborative innovation system of medical professionals and information technology professionals, compensate for each other's lack of professional skills, deal with interdisciplinary problems in the collection of human physiological parameters, and gradually develop and provide high-precision, high-reliability intelligent sensor products or multi-parameter detection system integration products.
In the realization of family life facility control, chronic disease monitoring and management, personal emotional escort functions, the sensor should carry out a series of process scientific research and development, experiment and research such as different appearance structure design, parameter index detection and calibration, continuous aging test, uniformity correction and compensation according to the functional requirements of terminal products and machinery and equipment, and form specifications for product, and also have the research, development and innovation of industrial production process equipment and tooling fixtures to adapt to batch support. In addition, sensor products must meet the special requirements of long-term use of consistency, high reliability, low cost, and stability indicators, which is the key point and problem of sensor process research and development. He suggested that first of all, we must do a good job in top-level design, create clear goals, and do a good job in the construction of standards and norms; Second, we should deal with many problems existing in existing architecture, service platforms, industries and enterprises; Third, we should formulate corresponding precise policies to guide and support industrial development; Finally, an accurate evaluation system should be created, a demonstration effect should be formed, and after the successful pilot, it is gradually promoted from point to surface, so as to fully bloom.
Health care is the pain point of the elderly, and wearable physiological signal monitoring devices, portable body fluid detection and other health sensor devices and systems are the basis for good health management. Sensor companies must first meet the low cost of guaranteed performance, which is possible in the case of massive demand. Secondly, the intelligence of sensors and the IoT will also be an important development direction in the future. Domestic sensor companies should grasp these two points.
Because the market prospect of smart elderly care hardware equipment is bright, once the bottlenecks such as related applications and costs are improved in the future, the continuous growth of the market can be expected. Therefore, in the field of smart elderly care, start-ups with technology and cost improvement potential and companies in the relevant industry chain deserve the close attention of investors.
