Abstract
A method and apparatus generate electrical currents and/or voltage in tissue using particles composed of liquid crystals and magnetic particles.
Claims11
A method for stimulating neural tissue, the method comprising:
- positioning at least one device within a 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 in a vicinity of the neural tissue, wherein the electrical energy is produced in response to a change in configuration of liquid crystals in the liquid crystal solution.
A method for altering and monitoring an electrical state of neural tissue, the method comprising:
- positioning at least one device within the neural 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 to the neural tissue, wherein the electrical energy is produced in response to a change in configuration of liquid crystals in the liquid crystal solution:
- and remotely sensing a status of the at least one device.
