An autonomous intracorporeal capsule comprises a body containing electronic circuits and an energy harvesting module. The energy harvesting module comprises a moveable surface on the body of the capsule, subjected to pressure variations and to produce a mechanical stress under the effect of the pressure variations, and a transducer comprising a deformable piezoelectric component configured as a beam adapted to be forced to bend. The piezoelectric component has a recessed end integral with the capsule and a free end. A mechanical connection couples the free end of the piezoelectric component to the actuator. The mechanical connection may provide a degree of freedom in rotation between a main direction of the beam and the direction of application of the mechanical stress.

The energy harvester module of the capsule comprises: a primary oscillating structure subjected to an external low-frequency stress; a secondary oscillating structure comprising an elastic element and able to vibrate in high-frequency resonance; and an electrostatic structure with a first electrode coupled to the primary structure and a second electrode coupled to the secondary structure. The electrodes exert a mutual attraction between them driving the secondary structure away from its stable equilibrium position with tensioning of the elastic element, up to a limit beyond which the secondary structure is released by relaxation effect to vibrate at a resonance frequency. A transducer coupled to the secondary structure converts these high frequency vibration movements into electrical energy.
