Based on the liquid resonance principle, a novel sensing technology for detecting the blood coagulation was proposed. The course of blood coagulation can alter its inherent properties, such as viscosity and density. As a result, liquid resonance frequency of blood will change with the blood agglomeration. A gold-plated Interdigital Electrode (IDE) was fabricated and a detection system was designed for the acquisition of the frequency. The activated partial thromboplastin time (APTT) was

For four volunteers, the activated partial thromboplastin time measured is 22-37 seconds, which are consistent with the reference value 22-38 seconds. The results indicated that the liquid resonance frequency can characterize the course of blood coagulation.
