Abstract

Embodiments disclosed herein are directed to systems configured to power at least one device disposed in a living subject, apparatuses configured to be disposed in a living subject and export power stored in an energy-storage device, and related methods of powering at least one device disposed in the living subject.

Claims

1-49. -49. (canceled)

50. A system, comprising:

an optical-electrical converter configured to be disposed within a living subject, receive one or more first optical signals transmitted transdermally into the living subject, and convert the one or more first optical signals into electrical energy;

an energy-storage device configured to be disposed within the living subject and coupled to the optical-electrical converter to receive at least a portion of the electrical energy therefrom, the energy-storage device further configured to store the at least a portion of the electrical energy received from the optical-electrical converter; and

an electrical-optical converter configured to be disposed within a living subject and coupled to the energy-storage device, the electrical-optical converter further configured to receive the at least a portion of the electrical energy from the energy-storage device and convert the at least a portion of the electrical energy into one or more second optical signals.

51. The system of claim 50, wherein the optical-electrical converter includes one or more photodiodes.

52. The system of claim 50, wherein the energy-storage device includes a capacitive device.

53. The system of claim 50, wherein the energy-storage device includes a battery.

54. The system of claim 50, wherein the electrical-optical converter includes one or more light-emitting devices.

55. The system of claim 50, further comprising one or more optical waveguides optically coupled to the electrical-optical converter and configured to guide the one or more second optical signals to a selected location within the living subject.

56. The system of claim 55, wherein the one or more optical waveguides include one or more optical fibers.

57. The system of claim 55, further comprising at least one device including an additional optical-electrical converter positioned to receive the one or more second optical signals from the one or more waveguides and configured to convert the one or more second optical signals into one or more electrical power signals that power the at least one device.

58. The system of claim 50, further comprising a beam director configured to direct the one or more second optical signals.

59. The system of claim 50, further comprising an optical element configured to focus the one or more second optical signals.

60. The system of claim 50, further comprising a biocompatible packaging enclosing at least one of the optical-electrical converter, the energy-storage device, or the electrical-optical converter.

61. The system of claim 50, further comprising an external optical power source configured to output the one or more first optical signals.
