在可穿戴設(shè)計(jì)中延長電池壽命

　　他身打扮市場蓬勃發(fā)展。數(shù)據(jù)聚合門戶網(wǎng)站Statista，指出全球市場的價(jià)值將超過70億美元，今年126億美元的2018。

　　雖然潛在的回報(bào)很高，但這不是一個(gè)容易進(jìn)入的市場。設(shè)計(jì)智能手表或健身手鐲是艱難的，消費(fèi)者期望大量的功能，智能手機(jī)連接，緊湊型的因素，重量輕，電池壽命長。高度集成化、超低功耗微處理器和無線芯片的引入緩解了設(shè)計(jì)過程，但擠出所有電池的功率仍然是可穿戴產(chǎn)品成功的關(guān)鍵。

　　本文以如何幫助服飾設(shè)計(jì)師芯片供應(yīng)商提供節(jié)能顯示延長電池的壽命，一看，微控制器（MCU），硅收音機(jī)和電源管理芯片專為超低功耗應(yīng)用。

　　Convergence of technology

　　Wearables have sprung to the fore because of the convergence of three key technologies1. Ultra-low-power chips that can run from watch batteries allow companies to offer compact products which， thanks to smartphone-compatible wireless technology such as Bluetooth Smart（also known as Bluetooth low energy）， communicate seamlessly with smartphones and tablets. A range of inexpensive apps presents the information gleaned from the wearable in a user-friendly format indicating， for example， how long the user needs to exercise to lose weight. A recent leading-edge wearable is adidas’ Fit Smart wristband tracker which incorporates Bluetooth Smart technology from Nordic Semiconductor （Figure 1）.
