The WaVeMe testing system makes the measurement of soil stiffness at very small strains easy. It consists of piezo-ceramic plates, known as P and S sensors, which operate in the same way as bender elements. The system is used to measure compression wave (V_P) and shear wave velocity (V_S) of a specimen.

Each WaVeMe system comes equipped with combined pairs of piezoceramic plated P and S sensors – one serves as the output (or source) signal and the other receives the signal (or input). These sensors vary by system type and can be used with static and cyclic versions of direct simple shear, triaxial, and resonant column-torsional shear systems.
