Due to factors such as population aging and the increase in lifestyle diseases, the medical electronics market is expected to grow rapidly. A medical electronics market research report shows that in 2021, the global medical electronics market size reached RMB 32.577 billion. The report predicts that by 2027, the global medical electronics market size will reach RMB 71.569 billion, with a compound annual growth rate of 14.02% during the forecast period. Compared with the consumer electronics field, the growth of the medical electronics field is long-term and stable. With the increasing number of sub-healthy people in China, data from 2019 showed that 835 million people in China suffer from chronic diseases. As people pay more attention to their health with the development of the times, the Chinese medical electronics market is therefore growing. As medical electronics develop towards intelligence and portability, higher requirements are placed on MCUs.
