Latest Patents

One of Wu's latest patents is focused on piezoelectric vibrational energy harvesting systems. This invention incorporates parametric bending mode energy harvesting, utilizing vibrational energy harvesting (VEH) structures that include resonant beams. Each beam has a fundamental resonance frequency and a parametric mode frequency, along with at least one piezoelectric layer that generates electrical charge in response to both types of excitation. The invention also includes circuitry designed to harvest the electrical charge from the resonant beam. Notably, the parametric mode frequency can be tuned to be close to the fundamental resonance frequency, enhancing the effective bandwidth of the VEH structure. Furthermore, the effective bandwidth can be increased by tuning multiple parametric-mode-enabled resonant beams to slightly different frequencies.

Another significant patent by Wu is an implant wear debris detection apparatus and method. This system is designed to detect wear debris particulate from a medical implant within the body of a living animal. It includes an acoustic transmitter that transmits acoustic energy to a soft tissue region near the medical implant. An acoustic receiver detects the resultant acoustic energy generated by the wear debris particles, producing a received signal indicative of the particles. A processor evaluates parameters associated with the wear debris, and an output indicates these parameters.
