Abstract
A method for powering an autonomous intracorporeal leadless capsule includes the step of receiving a slow pressure variation at an external surface of a deformable member on the capsule. The deformable member is displacing in response to the slow pressure variation. The method further includes using a high pass mechanical filter to prevent the displacement from being transferred to an energy harvesting circuit within the capsule. The method further includes receiving a fast pressure variation at the external surface of the deformable member on the capsule, the deformable member displacing in response to the fast pressure variation. The method further includes via the high pass mechanical filter, passing the displacement to the energy harvesting circuit and creating energy using the displacement provided to the energy harvesting circuit.
