This rechargeable portable bracelet cleverly combines solar power, biofilm energy, and kinetic energy storage, offering a green smart wearable experience. The high-efficiency solar panels on its surface capture light and convert it into electricity. Simultaneously, utilizing biofilm technology, it transforms body heat and moisture into additional power, enhancing energy efficiency. The bracelet also features a kinetic energy conversion module that stores the wearer's motion as electrical energy. High-precision sensors record real-time motion data, syncing with a mobile app for user analysis.
