| 中文摘要 | 本成果實現「收集環境電磁輻射」與「身體動能」的穿戴能源技術，實現世界上第一個可以從環境收集電磁波能量與身體動能的多功能「發電」與「感測」彈性纖維。 所有電器在使用、高壓電塔、手機通訊時，都會產生電磁輻射，這種能量通常會藉由儀器的介電材料所散失，介電材料的分隨電磁波的連續極化，最後變成熱能；就是一般所稱的介電損耗。我們利用新元件物理與材料，實現回收環境的電磁波能量，以及身體動能，做為新的穿戴能量來源。除了發電外，此發電纖維同時可以擷取生體機械能，轉換成電訊號，實現自發電、自驅動、零功耗的生理感測使用。 這是世界上第一次能夠「回收環境電磁輻射」而發電的紡線；同時，可以回收「人體運動」的能量；不僅如此，發電纖維也可作為主動式、自驅動的生理感測使用；這項成果提供物聯網、遠端、離散、穿戴等能源與感測技術破壞性的新啟發。 |
| 英文摘要 | Future wearable technolgies and personal electronics may benefit from e-textiles that simultaneously possess high elasticity and multiple capabilities such as energy harvesting and sensing. Here, we present the first elastic multifunctional fiber that can scavenge mechanical energy from body motion and electromagnetic energy from surrounding electronic appliances. In addition to converting multiple sources of waste energy into electricty, the fibers can also serve as self-powered tactile and biomechanical sensors. The fibers consist of hollow elastomeric fiber filled with liquid metal. The fibers harvest energy by the combination of triboelectricity (160 V/m, 5 μA/m, and ~360 μW/m) and induced electrification of the liquid metal (8 V/m (60 Hz), 1.4 μA/m, and ~8 μW/m). We characterize the fibers and demonstrate their utility for powering electronics and sensing biomechanical information. These fibers are further demonstrated as completely soft and stretchable components for human-machine interfaces, including keypads and wireless music controllers. |
