Zusammenfassung: | Nanogenerator technology provides a wide range of application prospects for the development of flexible devices. In recent years, the emergence of functional polymers such as piezoelectric and friction polymers has promoted the development and application of flexible nano-energy. This study proposes a new method to directly write magnetostrictive fiber ribbons onto biocompatible substrates using electrohydrodynamic printing technology. It not only meets the application needs of nano-energy, but also realizes the wireless “radiation” of electromagnetic energy to the receiving devices. Firstly, the Fe

alloy is deposited on a polyethylene terephthalate substrate using electrohydrodynamic printing. The reciprocated and loop structures of magnetostrictive ribbons are printed, with dimensions of 45 mm × 15 mm × 0.2 mm. Subsequently, the deformation of fiber ribbons is measured under the Helmholtz magnetic field to verify the magnetostrictive positive effect. The results validate that fiber ribbon exhibits the expected properties of magnetostrictive materials. Furthermore, its ability to harvest vibration energy and convert it into magnetic energy and electrical energy is further verified by applying sinusoidal vibration to fiber ribbon to test whether an induced voltage is generated. The results demonstrate that the magnetic domains within fiber ribbon deflect and move under the mechanical force, so fiber ribbon has the ability of magnetostrictive inverse effect. |
