Abstract: The present invention is generally related to an anti-leaking cartridge and anti-leaking ink. The anti-leaking ink comprises: an organic solvent, which is selected from the group consisting of diethylene glycol, triethylene glycol, triethanolamine amine extra pure, polyethylene glycol 200, and ethylene glycol and functions with at least one seal member for avoiding leakage; at least one dye dissolved in the organic solvent; a buffer solution maintaining the pH value of the anti-leaking ink in between 6.0 to 8.0; an antibacterial avoiding that the properties of the ink is changed; surfactant, which homogenizes the aquas of ink and the organic solvent; and de-ionized water.

Abstract: A portable electronic device with fat measuring function and a fat measuring method thereof are provided. The portable electronic device includes a first button, a second button and a fat-measuring controlling circuit. The first button and the second button are made from a conductive material. The fat-measuring controlling circuit is coupled with the first button and the second button respectively. When the user touches the first button and the second button, the fat-measuring controlling circuit measures an electrical signal between the first button and the second button to generate the user's body fat rate.
