摘要： An energy harvester includes a frame having a base, a first side member affixed to the base, and a second side member affixed to the base and spaced apart from the first side member. A beam is coupled between the first side member of the frame and the second side member of the frame. The beam has a substrate layer with a first end affixed to the first side member of the frame, a second end affixed to the second side member of the frame, a first face, and a second face opposite to the first face. The substrate is elastically deformable in response to the vibratory force. The beam further includes a first piezoelectric layer joined to the first face of the substrate layer and having a terminal for electrical connection to a load, the first piezoelectric layer comprising at least one piezoelectric patch.

摘要： 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.

摘要： A piezoelectric resonator including a base part, a first support part fixed to the base part, a beam part fixed to the first support part, a weight part fixed to the beam part, a drive unit provided on the beam part, and an adjusting magnet movable on a main surface of the base part. Furthermore, the weight part is formed of a magnet or a magnetic body, and the beam part extends in a direction along the main surface of the base part. With this configuration, displacement of the resonance frequency generated due to variation in a manufacturing process can be adjusted easily. Even when the resonance frequency is displaced from desired resonance frequency due to variation in the manufacturing process of a power generating element, the displacement can be easily adjusted and maximum efficiency can be obtained.
