"high inductance density (280–390 nH/mm2, about 10X higher.), reduced energy consumption, suitable for low-frequency applications... high-precision femtosecond laser ablation crafted without inducing crystallization... reduces magnetic leakage to <10-4 T minimizing interference between components... inductance density increases to about... can be stretched 3X, while retaining performance with only <10% decayed inductance value and quality factor after 2,500 bending cycles at 16-mm bending radius"
