Abstract
A method and apparatus generate electrical currents and/or voltage in tissue using devices composed of liquid crystals and magnetic particles. An instrument applies one or more magnetic fields to the devices to produce electrical energy.
Claims16
A system comprising:
- at least one device being no more than 100 microns in any single dimension, containing at least one magnetic particle in a liquid crystal solution, and configured to be positioned in living tissue;
- and
- an instrument, configured to be positioned internal or external to a body containing the living tissue, for applying a magnetic field to the at least one device to produce an electrical field for application to the living tissue.
A method for changing an electrical state of at least one device present in living tissue, the method comprising:
- positioning the at least one device within the living tissue, wherein the at least one device is no more than 100 microns in any single dimension and contains at least one magnetic particle in a liquid crystal solution;
- and
- applying one or more magnetic fields to the at least one device to produce electrical energy.
A method for altering and monitoring an electrical state of at least one device present in living tissue, the method comprising:
- positioning the at least one device within the living tissue, wherein the at least one device is no more than 100 microns in any single dimension and contains at least one magnetic particle in a liquid crystal solution;
- applying one or more magnetic fields to the at least one device to produce electrical energy;
- and
- remotely sensing a status of the at least one device.
