A sensor device () and a method for measuring a viscosity of a sample of a liquid. The sensor features a chamber () for receiving the sample of the liquid, two electrodes () disposed either on the surfaces of the chamber, but possibly isolated from contacting the sample, or electrodes located externally to the chamber, and a capacitance measuring circuit (). The sensor is used by connecting to a measurer for determining a capacitance on the electrodes, such that the capacitance directly reflects a volume occupied by the sample of the liquid. Preferably, the liquid is blood and the capacitance is used to determine the clotting time of the blood. Also preferably, a cover for the chamber is provided with at least one aperture, which more preferably is a mesh. Alternatively, an electrical property such as the amplitude of current passed through the sample is used to determine clotting time. Also preferably, the time period required for the maximum capacitance to be reached could be measured. Alternatively, the capacitance could be measured after a fixed time period () had elapsed. Also alternatively, the time period required for the maximum current to be reached could be measured, or the amount of current could be measured after a fixed time period had elapsed. In preferred embodiments of the present invention, a kit for measuring the clotting time of blood is provided. In other preferred embodiments of the present invention, methods are provided for using the kit and device of the present invention.
