随着可穿戴设备的普及和消费者对物联网（IoT）功能的期待，超低功耗的需求比以往任何时候都更加重要。通过利用超低功耗处理器等超低功耗解决方案，制造商可以创造出更可持续、更智能的边缘设备，以满足消费者的需求。以下是超低功耗可穿戴设备为消费者、制造商和我们的环境带来的一些显著优势。
消费者福利
For wearable users, the advantages of a device running on ultra-low power are obvious. By consuming far less energy, battery-powered edge devices can be worn for much longer without recharging. All types of IoT wearables, whether they are smartwatches, fitness bands, predictive health devices, or even animal trackers, provide a better user experience with longer battery life. With ultra-low power electronics, you can go weeks or even months without needing to recharge. More, given low power, manufacturers can enable consumers to use smaller batteries, allowing for thinner form factors and sleeker design.
There are many inherent disadvantages if you need to recharge your smartwatch daily. First, it’s very common among users to accidentally forget plugging the device for charging before going to bed, which renders the device lifeless in the morning. Second, when your smartwatch is plugged in to recharge its battery, it’s not on your body monitoring vital data. As a result, it will be more difficult for the device to identify trends and generate health insights. However, if your smartwatch can operate for days, weeks, or even months without needing to recharge, it can continuously monitor your biometric data and alert you to any potential concerns.
制造商的优势
Many consumers are picky about appearances, especially for products they will wear on their person. Manufacturers often minimize the form factor for a sleek and slim design which inadvertently sacrificing the battery size. Because consumers don’t want a massive battery in their smartwatch or fitness tracker, manufacturers had to compromise with smaller batteries that wielded less power. However, with the emergence of technologies like ultra-low-power microprocessors, wearable manufacturers can win over consumers with devices that are both fashionable and massively energy efficient.
超低功耗技术使制造商能够制造出具有先进心率传感和压力监测功能的更智能设备。为使这些功能发挥预期作用，它们必须始终保持开启状态。但是，如果没有超低功耗 MCU，智能配件上始终开启的传感器可能会在几分钟内耗尽电池寿命。此外，许多设备通过蓝牙等射频技术实现近乎不间断的无线连接，而没有智能电源管理是不可能实现的。最后，随着人们对 "始终在线 "功能的期望，对 "始终在线 "语音命令系统的需求也随之而来。
环境效益
With wearable devices playing a more significant role in the way we live, work, and play, it would be negligent to not consider the impact these electronic accessories have on the environment around us. With ultra-low power technologies becoming more available, a new generation of smart wearable devices will be more sustainable and eco-friendlier. More efficient devices equal less energy consumption, which helps reduce CO2 emissions, shrink the overall carbon footprint, and ushers a sustainable lifestyle for a better and safer environment.
As the shift to more sustainable electronics continues, we can look forward to ultra-low power technology components contributing to a lower carbon footprint. Thanks to ongoing innovation, wearable devices will continue to shrink and provide around-the-clock connectivity thanks to the Internet-of-Things (IoT). As such, it’s vital for industry leaders to build crucial pieces of technology that will enable solutions that provide the maximum amount of power for the least amount of energy.
