title: Transmitting electric energy through a closed elastic wall by acoustic waves and piezoelectric transducers.
abstract: Transmission of electric energy through a closed elastic wall by piezoelectric transducers and acoustic waves is studied based on the linear theory of piezoelectricity and elasticity. A theoretical analysis is performed. For the structure and motion considered, the 3-D equations of linear piezoelectricity reduce to a 1-D mathematical problem. An exact solution is obtained. Transmitted voltage, current, power, efficiency and stress distribution are obtained. Their dependence on various parameters is examined. The model and results of this paper are closer to real situations compared with those in a previous analysis.
