Although the global smart watch market has shown an overall decline, many manufacturers have withdrawn from the market or have suddenly closed down. However, Apple Watch has still gained a lot of users and become the monopolist in the smart watch market. This year, Apple may launch the third generation of watches, and according to foreign media latest news, three generations of Apple Watch is likely to launch a major upgrade to support the measurement of blood glucose levels. According to the U.S. tech news site BGR, people familiar with the matter reported that Apple is developing technology to measure blood sugar through Apple Watch, which will be released in the third generation. However, the specific way to achieve it is still unknown. Diabetes is a common disease in the world. There are 30 million people with diabetes in the United States alone. People with diabetes need to constantly monitor their blood sugar levels. If Apple Watch can make simple measurements, it will undoubtedly be a major technological advance. Currently, patients rely mainly on blood samples to measure blood glucose levels or through a simple device that pierces the skin. These measurements have caused pain to the user. Obviously, blood glucose measurement is a huge area of ​​innovation. How to measure blood glucose levels for Apple Watch, the media speculated that Apple may add a wrist watch wrist watch accessories, set the wrist to measure blood sugar, and Apple Watch to maintain communication. In addition, Apple may also improve watch strap, through the addition of camera technology to achieve under the piercing the blood glucose measurement. It is worth mentioning that this is the first news media coverage of the new Apple Watch will support blood glucose measurement, but last year the media reported that Apple is developing related sensor technology for direct measurement of blood glucose levels through skin contact. According to CNBC, the financial news website of the United States, Apple has set up a R & D team in Palo Alto to develop blood glucose sensor technology, while some engineers have had five years of R & D experience in this field. It is reported that Apple's research and development work has made important progress, and even in some hospitals in Taiwan, China conducted clinical tests. In addition to hardware development, Apple hired consultants to address government health regulatory policies that measure blood glucose through smartwatches. It is reported that Apple's team to develop this technology, a total of more than 30 people, many of whom come from well-known biomedical companies. In addition to Apple, Google (microblogging) is also developing new technologies for measuring blood sugar. It is reported that Google was prepared to measure user's tears through contact lenses to measure blood sugar level, but this project is slow and difficult. In addition, Google is also working with other companies to develop new devices to measure blood sugar. If we can launch a third-generation Apple Watch that supports glucose measurement, it will undoubtedly bring a huge boost to the sales of this product. As we all know, Apple Watch is the first time Cook has led Apple into a new category (in fact, Apple is a latecomer to the smart watch market), but this product has not become comparable to the iPhone's pillar business. Due to flat sales, Cook and Apple management until today, has never disclosed the specific sales of Apple watches, this behavior is quite rare in Apple's history. However, third-party reports show that at present, Apple has gained half of the smart watch market share, some analysts believe that the overall smart phone market prospects slim, but Apple Watch can rely on Apple's brand to continue to survive. The industry generally believes that the first generation of Apple Watch walked a lot of detours, introduced tens of thousands of dollars in the gold version of the watch, hoping to become a popular fashion product, but was a huge defeat, Apple has canceled the luxury positioning. In addition the first generation of watches basically repeat too many functions of the smart phone, the user interface haphazard, in the face of too many features ported from the phone over, consumers think Apple Watch is not as a selling killer function. Fortunately, on the second generation of Apple Watch, Apple made a major adjustment, emphasizing the health function of exercise, rather than a omnipotent information device. Second-generation watches increased GPS chips, better monitoring of distance movement, the other can support swimming wear. In addition Apple also Nike co-operation, introduced a customized version. The clearer positioning of "Sports and Health Devices" has led to a pickup in sales of Apple watches, with more than half of the quarterly drop that occurred last year has been eased. However, last year, the total sales of Apple Watch still showed a 7% decline. In March, Wall Street analysts quoted supply chain sources as saying that it is possible for Apple to study rivals such as Samsung Electronics and LG, and to allow Apple Watch to insert a SIM card and be able to access and talk through the mobile base station independently. This means that Apple Watch will completely get rid of the iPhone, to become a completely independent electronic devices. For enthusiastic outdoor users, the independent use of Apple Watch will bring more practical value. This article is reproduced, does not represent the world position of million table.
