A method of measuring water content of wood is introduced. This method uses a vibration technique. A shaker driven by swept sine signals was used for the accurate measurement of vibration. A cylindrical wood was used as a sample to verify our method of measuring the water content. The resonance frequencies of the wood sample decreased as its water content increased. Also, we performed an experiment of measuring the vibration of a tree to explore the feasibility of applying the method to the measurement of tree water content. The circumferential mode that is independent of the height of a tree was identified using a white oak tree.
