Embodiment Construction

[0049] The detailed description set forth below in connection with the accompanying drawings serves as a description of a number of different configurations. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. Several aspects of the apparatus and methods are described in terms of a number of different blocks, functional units, modules, elements, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). Depending on the particular application, design constraints, or other reasons, these elements may be implemented using electronic hardware, computer programs or any combination thereof.

[0050] Electronic hardware may include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), gat...

Abstract

The present invention discloses a self-powered electrode array which is used in a cochlear implant device. The cochlear implant device comprises an inductive antenna, a stimulation unit, an electrodearray, and an energy harvesting apparatus. The inductive antenna is configured to receive energy to operate the cochlear implant and to receive signals for a stimulation of a cochlea via an electrodearray comprising a plurality of electrodes. The stimulation unit is configured to process the signals received by the inductive antenna to be usable for the electrodes of the electrode array. The electrode array is configured to apply the signals processed by the stimulation unit to the cochlea for the stimulation thereof. The energy harvesting apparatus is connected to the stimulation unit or tothe electrode array, and is configured to harvest energy based on at least one of thermal, biochemical, biophysical, and mechanical processes / phenomena pertaining to the cochlea, and is configured toprovide harvested energy to the stimulation unit or the electrode array, respectively.

Description

technical field [0001] The present invention relates to self-powered electrode arrays. More specifically, the present invention relates to a hearing device having a self powered electrode array comprising an energy harvester for providing energy to the hearing device. Background technique [0002] Currently, commercially available cochlear implants are powered by a non-implantable energy source, ie an external energy source. Such energy is typically provided by speech processors in a behind-the-ear (BTE) or "button processor" form factor. The battery is typically a non-rechargeable zinc-air battery or a rechargeable lithium-ion battery. [0003] Energy is transferred to the cochlear implant via an inductive link established by coupling together two coils: one coil outside the body coupled to the other coil integrated in the implantable device (cochlear implant). However, the yield of energy transfer (energy transfer efficiency) is usually only about 25%. [0004] For the...
