The wearable device industry is moving towards market segmentation and diversification of demand

     With the development of technology, in addition to smart watches, smart bracelets, wearable headphones and other products, there are also smart rings, smart clothing, smart glasses, brain computer devices and other wearable medical devices. Wearable devices can be seen in consumer electronics, industrial, medical, military and other fields.Currently, the wearable device industry is moving towards market segmentation and diversification of demand. In the face of the rapid development of the wearable device market, should we pursue smart wearable, or should we wear smart?

     In fact, intelligent wearing is more meaningful, because intelligent wearing should be based on wearing, and then consider the necessity and feasibility of intelligent wearing, based on the performance and bearing function of wearing products. This takes into account the size, weight and battery life of the product itself. Looking at these dimensions, he thinks smartwatches and smart glasses are better suited to smart-worn devices. Wearable intelligence requires wearability, functionality and intelligence. Among them, intelligence requires wearable devices to have perception, connection, computing and other capabilities. Technically speaking, the wearable device industry is moving towards low power consumption, independent cellular, smart applications and information security.

    So, what challenges will upstream manufacturers face? This can be seen in the trend of wearable devices. In terms of market segmentation, smartwatches, for example, cover all age groups of children's watches, adult watches and health watches. Faced with market segments, we want the chip platform to be sustainable and scalable, which is the result of products developed by the previous generation, Li said. The latter generation can inherit the same chip platform and support products at different prices or even in different sectors, thus reducing resource investment.

     In terms of users, there is a trend of diversified demand. For example, the need for complete product functionality will create new challenges for low-power technologies; In addition, the smart wearable requires the sensor BCW70LT1 to collect personal information, so information security is also very important. On the other hand, since wearable devices require portable smart applications, there are new requirements for cellular networks and portable smart applications.

     According to Counterpoint Tresearh, cellular stand-alone smartwatches accounted for more than 35.7 percent of the world's total in the first half of 2022, most of which are children's smartwatches equipped with cellular networks. In this development, eSIM technology provides crucial technical support for cellular smartwatches.

     Currently, AppleWatchUltra, Huawei WATCH3Pronew, OPPOWatch3Pro and other high-end smartwatches also support cellular networks. WATCH3Pronew Apple can support 4-21 days of battery life AppleWatchUltra low-power mode, battery life can also reach 36-60 hours, want to know the previous battery life, compared with domestic smart watches, Battery life for the AppleWatchUltra was around 18 hours from the first to the sixth generation, but the battery life was a little bit worse, and improved battery life was a big step forward as the screen got bigger and richer.

     Therefore, how to improve the performance of domestic smartwatches while ensuring battery life? It is reported that Huawei Watch3Pro and OPPOWatch3Pro use dual-core architecture design, high performance chip and low power chip cooperation, according to the actual use of users power saving, to achieve typical intelligent mode scenarios, heavy scenarios and ultra-long durability.

     In addition to the two-core structure, of course, other structures are needed. AI and algorithm, etc. For example, due to the accumulation of smart wearable low-power technology, Unigroup Zhanrui independent research and development. UCVS four-series Full scene power optimization strategy GRTOS watch platform W117 also supports this strategy. On the other hand, Unigroup is introduced into the DVFS frequency conversion and multi-level power management mechanism, which can realize modular power control in different scenarios. Smartwatches can achieve a week of battery life when the cellular network is turned on.

     Cellular independent smartwatches have become an obvious development trend, which has been clearly reflected in children's watches, and adult smartwatches will gradually use cellular networks in the future. Li believes that wearables will be self-contained, and that the MCU+W117 solution can achieve two weeks of battery life in a normal usage scenario, just to meet the independent needs of the cell, with battery life in mind. In addition to the constant iteration of the main control platform, other players in the chain still need to overcome the battery life challenge.
