A multi-functional sensing device is provided to measure temperature and permittivity at the same time by using first, second, and third electrodes sensing the temperature and permittivity and a sensing layer improving the sensitivities of the first, second, and third electrodes. A multi-functional sensing device(100) is composed of a base(10) on which electrodes are installed; first and second electrodes(21,22) arranged on the upper side of the base to detect the permittivity of oil; a third electrode(23) connected to the second electrode to sense the temperature of oil; and a sensing layer(30) formed on the upper side of the base where the first, second, and third electrodes are formed, in order to improve the sensitivities of the first, second, and third electrodes. |
