    Abstract: As damping reduction can potentially lead to performance enhancement in certain applications, a scheme based on the concept of piezoelectric circuitry that yields reduced damping effect in a structural system is developed. The piezoelectric circuitry consists of an inductor and a negative resistance circuit serially connected to the piezoelectric transducer that is bonded/embedded to the structure. By using the negative resistance element to reduce the overall resistance of the circuitry to be negative, the resonant vibratory response of the structural system becomes higher while the system remains stable. The stability boundary of the negative resistance is derived for both the ideal piezoelectric transducer model and the transducer model with energy loss. The results are validated via experimental investigations.
