The limited battery life of smart watches and wristbands remains a pain point. We designed an embedded and compact electromagnetic generator so that these wearable gadgets can be self-powered. Applications include pedometer, sleep monitoring and GPS. Unlike existing products, the invention uses a novel magnetic frequency-up converter and harnesses the kinetic energy of human motion. A converter transforms the low-frequency arm swing to achieve desirable output power.

有限的電池使用時間一直是智能手錶和手環的應用痛點。針對這個問題，我們設計出一個可嵌入穿戴設備的小巧型磁力發電機，讓這些設備可自動發電，以支援計步器、睡眠監控及GPS定位等功能。與現有產品不同，這個發明採用新型磁力升頻器， 能有效收集人體動作所產生的動能，從而在低頻率的手臂擺動中仍能轉化出理想的輸出功率。
