In this project a new concept of charging implanted devices through the means of acoustic energy harvesting. The harvester used in this study is a resonator tube that would amplify the bending stresses on the lead zirconate titanate piezo electric material (PZT) cantilever inside of it at the resonant frequency. A sweep of different frequencies from 5Hz-70Hz were tested and results were recorded to measure the best output. This output energy can then be stored and used to charge implanted medical devices. Measures were also taken in efforts to secure the system from physical layer attacks that would disrupt the charging process. Different attack configurations were analyzed to understand how they can be executed in real-life scenarios. The maximum voltage recorded was at 45Hz at 0.74V. Attacks on the system were also successfully simulated, and the result is that they were observable and not discrete.
