This paper presents the measurement of the shear wave velocity at the Soil Mechanics Laboratory of the Department of Civil and Environmental Engineering Technology, College of Industrial Technology, King Mongkut's University of Technology North Bangkok. The research purposes a new technique to measure the shear wave velocity by using the piezoelectric film. This piezoelectric film is a very thin, light and high sensitive sensor and is used as a receiving sensor. The details of this new technique and its interpretations on Bangkok clay material are explained. The research found that this new technique is a reasonable technique, giving the shear wave velocity result in good agreement with the shear wave velocity data of the field test.
