    • An input device of capacitive touchpad is capable of generating an inducing capacitance through holding by a user. The claimed input device includes a pen nib which is made of/from an electric-conductive material, a pen body providing wider holding area for the user and a connect part for holding by the user. The pen nib and the connect part have an inlaying component in pairs such as mortise to lodged in or inset into each other. The pen nib may be made of/from an elastic or soft electric-conductive material which is made of/from a polyester compound doped or mixed with a metal powder or having metallic covering stuffed with the elastic or soft electric-conductive material for increasing the contact surface area. Accordingly, the present invention solves the available pad area shortening problem and the capacitance sensing variation result from the sweat of finger.
    • 电容式触摸板的输入装置能够通过用户的保持来产生感应电容。 要求保护的输入装置包括由导电材料制成的笔尖,笔体为用户提供更宽的保持区域以及由用户保持的连接部分。 笔尖和连接部件具有成对的镶嵌部件,例如榫眼,以嵌入或彼此插入。 笔尖可以由弹性或柔性导电材料制成,该材料由掺杂或与金属粉末混合的聚酯化合物制成或具有填充有弹性或软导电材料的金属覆盖物,用于增加 接触面积。 因此,本发明解决了可用的焊盘区域缩短问题和手指汗液的电容感测变化结果。
