  • Piezoelectric vibrational energy harvester
    Patent number: 9590533
    Abstract: A vibrational energy harvester having a base and a piezoelectric transducer formed from a layer of piezoelectric material and extending between a first end at the base and a second end. At least a portion of the piezoelectric transducer is arranged in a back and forth pattern between the first and second ends. A magnetic component provides a magnetic field within which at least a portion of the piezoelectric transducer operates so that it exhibits nonlinear behavior. A biomedical implantable device using the vibration energy harvester can extract energy from heartbeat waveforms (heartbeats) to thereby power a device within the body.
    Type: Grant
