摘要：
Methods, systems, and apparatus for powering and/or recharging medical devices implanted within the body are described. An illustrative power generation module disposable within the interior space of an implantable medical device includes a module body that defines an interior cavity as well as a flexible diaphragm that spans the interior cavity. The flexible diaphragm includes a first electrical conductor, a piezoelectric layer disposed adjacent to the first electrical conductor, and a second electrical conductor disposed adjacent to the piezoelectric layer. The piezoelectric layer is configured to displace within the interior cavity and generate a voltage differential between the first electrical conductor and the second electrical conductor.
