HIGH POWER ULTRASOUND WIRELESS TRANSCUTANEOUS ENERGY TRANSFER (US-TET) SOURCE

摘要

A bio-implantable energy capture and storage assembly is provided. The assembly includes an acoustic energy transmitter and an acoustic energy receiver. The acoustic energy receiver also functions as an energy converter for converting acoustic energy to electrical energy. An electrical energy storage device is connected to the energy converter, and is contained within a bio-compatible implant for implantation into tissue. The acoustic energy transmitter is separate from the implant, and comprises a substantially 2-dimensional array of transmitters. The acoustic energy converter may also provide conditioned power directly to a load, connected to said energy converter.

主权项

1. A bio-implantable energy capture and storage assembly, for implantation into tissue comprising:
i. an acoustic energy transmitter and an acoustic energy receiver, said acoustic energy receiver also functioning as an energy converter for converting acoustic energy to electrical energy at a rate of at least 5 Watts; ii. an electrical energy storage device electrically connected to said energy converter, wherein said acoustic energy receiver-converter is contained within the device for implantation in said tissue; iii. an acoustic energy transmitter external to the body and separate from said implant, and wherein the transmitter comprises at least one transducer comprising a 2-dimensional array of elements arranged in a substantially regular 2-dimensional geometric shape on a support; and iv. a cooling system including a circulating coolant and heat exchanger for removing heat from the energy transmitter, tissue, and implant at a rate of at least 3 Watts; wherein said transmitter operates at a frequency in the range of 0.75 to 1.5 MHz.
