A new receiving transducer derived by piezoceramic bimorfh for the elastic wave measurement method suited on triaxial apparatus is developed. The bimorph receiver was employed on three geo materials, Toyoura sand, Silica sand and Hime gravel. The performance and results are verified comparing the results obtained by small strain cyclic loadings and wave measurement by Trigger Accelerometer methods. The received signals by Trigger Bimorph receiver and Trigger Accelerometer methods are directly compared and equivalent performance was observed.[This abstract is not included in the PDF]
