Bio-energy electronic cochlea

The utility model provides a bio-energy electronic cochlea which can be implanted into a living body. The bio-energy electronic cochlea is provided with an in-vivo part and an in-vitro part; the in-vitro part comprises an external microphone, a sound processor and a transmission coil pulse generator, wherein the in-vivo part comprises a stimulation receiver and a multi-channel electrode array and is also provided with a power generation part; the power generation part comprises a power generation main body, adjustment ends, an output electrode, an electric energy storage unit and a package layer, wherein the power generation main body wraps and surrounds an aorta, is of a multi-film structure, and comprises a piezoelectric material layer positioned on a centre layer, and a first electrode layer and a second electrode layer which are respectively positioned on the two sides of the piezoelectric material layer. The adjustment ends are positioned at the two ends of the power generation main body. The output electrode transmits electric energy to the electric energy storage unit. The package layer covers the surfaces of the power generation main body, the two adjustment ends, the output electrode and the electric energy storage unit. The implanted electronic cochlea disclosed by the utility model can be used for the lifetime without replacing a battery after being implanted once.
