Abstract
Described is a locomotive implant for usage within a predetermined magnetic field. In one embodiment magnetohydrodynamics is used to generate thrust with a plurality of electrodes. In another embodiment, asymmetric drag forces are used to generate thrust.
Claims24
An apparatus for wireless power and data transfer to an implantable device operating in a biological environment, the apparatus comprising:
- a wireless power transmitter operating at a power signal frequency and having one or more transmitting antennae configured to transmit a power signal modulated with data over a radio frequency (RF) carrier signal;
- and
- a wireless power receiver having one or more receiving antennae configured to receive the transmitted power signal as a received power signal, wherein the wireless power receiver in integrated into the implantable device;
- wherein the implantable device further comprises:
- a rectifier, a regulator, a digital controller, and a charging device that accumulates energy over time, and
- a demodulator that decodes data modulated on the power signal without synchronizing to the RF carrier signal.
An apparatus for wireless power transmission to an implantable device operating in a biological environment, the apparatus comprising:
- a wireless power transmitter operating at a power signal frequency and having one or more transmitting antennae configured to transmit a power signal over a carrier signal and a first match circuit with a tuned impedance;
- and
- a wireless power receiver having one or more receiving antennae configured to receive the transmitted power signal as a received power signal and a second match circuit with a tuned impedance, wherein the wireless power receiver in integrated into the implantable device;
- and
- wherein the implantable device further includes a rectifier and an adaptive loading network to compensate for varying load of the implantable device to maintain effective matching at the one or more receiving antennae.
