The behavior of the piezoelectric transducer was scrutinized to find the reasons for the quantitative discrepancy between the experimental and numerical results in the energy-recycling semiactive method. It was discovered that the effective resistance of the piezoelectric transducer decreases significantly with the number of free electrical vibration cycles. It is essential to use the experimental data obtained from the first half-cycle of free electrical vibration for obtaining an accurate resistance value, which contributes to the accurate performance evaluation, when the energy-recycling method is used. The measurements with a common measuring instrument may lead to the wrong evaluation of the method's performance.
