Electret Tape Transducer

Abstract

The report covers an initial program to establish the feasibility of a new line transducer based on an active ultrasonic electret tape concept. It describes a theoretical model based on a lumped-element harmonic electromechanical analysis and was programmed for a high speed digital computer to allow the assessment of the effects of fourteen transducer parameters. It also describes the method used for charging the electret layer, the techniques developed for fabricating samples of the transducer, the test procedures required to evaluate the active and passive performance characteristics of the samples, and refinements to the fabrication process necessary to develop long samples.
