    • PURPOSE: Functional shoes are provided to improve energy conversion efficiency and to endure external force repeated during walking. CONSTITUTION: Functional shoes comprise: a shoes body(110); an elastic airbag(120) which repeats contraction and expansion by an external force applied during walking; an air channel tube(130) which inhales air from an inlet and discharges air to an outlet; a check valve(140) preventing the suction of the air from the outlet during inflation of the elastic airbag and the exhaustion of the air to the inlet during contraction of the elastic airbag; a turbine(150) which is formed within the air channel tube and revolves; a generator(160) generating electromotive force by the rotation of the turbine; and an output terminal(170) which outputs electrical energy to the outside of the shoes body.
    • 目的:提供功能性鞋,以提高能量转换效率,并承受步行期间重复的外力。 构成:功能鞋包括:鞋体(110); 弹性气囊(120),其通过在步行期间施加的外力重复收缩和膨胀; 空气通道管(130),其从入口吸入空气并将空气排放到出口; 止回阀(140),其在所述弹性气囊的充气期间防止来自所述出口的空气的吸入,并且在所述弹性气囊的收缩期间空气向所述入口排出; 涡轮(150),其形成在所述空气通道管内并旋转; 通过涡轮机的旋转产生电动势的发电机(160) 以及向鞋体的外部输出电能的输出端子(170)。

    • A composition and a manufacturing method of lead-free piezoelectric ceramics are provided to improve the piezoelectricity characteristic by adding Li2CO3 and Na2CO3 to the ceramic composition. The manufacturing method of the lead-free piezoelectric ceramic composition comprises the following steps: the step that mixes and pulverizes the sample of the Na2CO3, K2CO3, Li2CO3, Nb2O5, and Ta2O5 and dries and burns; the step that re-burns the burned sample; the step for remixing, re-pulverizing the sample; the step for sintering and molding the dried sample. Li2CO3 and Na2CO3 are added to the ceramic composition of (NaxK0.95-xLi0.05)(Nb0.95Ta0.05)O3.
    • 提供无铅压电陶瓷的组成和制造方法,以通过向陶瓷组合物中加入Li 2 CO 3和Na 2 CO 3来改善压电特性。 无铅压电陶瓷组合物的制备方法包括以下步骤:将Na 2 CO 3,K 2 CO 3,Li 2 CO 3,Nb 2 O 5和Ta 2 O 5的样品混合并粉碎并干燥和灼烧; 重烧烧伤样本的步骤; 重新混合,重新粉碎样品的步骤; 烧结和模制干燥样品的步骤。 (Na x K 0.95-x Li 0.05)(Nb 0.95 Ta 0.05)O 3的陶瓷组合物中添加Li 2 CO 3和Na 2 CO 3。
