Varying the effective coil area for an inductive transcutaneous power link

摘要

A prosthesis including an external device and an implantable component. The external device includes a first inductive communication component. The implantable component includes a second inductive communication component, wherein the implantable component is configured to be implanted under skin of a recipient. The external device is configured to transmit power via magnetic induction transcutaneously to the implantable component via the second inductive communication component. The internal component is configured to receive at least a portion of the power transmitted from the external device via the inductive communication component. At least one of the first and second inductive communication components comprise an inductive communication component configured to vary its effective coil area.

1. A prosthesis, comprising:
an external device including a first inductive communication unit; and an implantable device including a second inductive communication unit, wherein the implantable device is configured to be implanted under skin of a recipient, wherein the external device is configured to transmit power via magnetic induction transcutaneously to the implantable device via the first inductive communication unit, wherein the implantable device is further configured to:
receive at least a portion of the power transmitted from the external device via the second inductive communication unit, andmeasure a value for a parameter of the second inductive communication unit, wherein at least one of the external device and the implantable device is further configured to determine an adjustment signal based on the measured value for the parameter, and wherein at least one of the first and second inductive communication units comprises an inductive communication component configured with an effective coil area for transmitting the power, wherein the effective coil area is variable based on the adjustment signal.
