Abstract
The present application relates to stacked piezoelectric composites comprising piezoelectric structures. Suitably, the composites are useful as tissue-stimulating implants, including spinal fusion implants. The present application also relates to methods of making stacked piezoelectric composites.
Claims9
A tissue-stimulating implant comprising:
- a. a piezoelectric composite, the piezoelectric composite comprising two or more layers, each layer comprising:
- i. a polymer matrix;
- and
- ii. a plurality of piezoelectric structures mechanically associated with the polymer matrix,
- wherein the layers are substantially adjacent to each other in a stacked configuration;
- and
- iii. an electrical connection connecting at least two of the layers of the piezoelectric composite;
- b. an electrically insulating encapsulation coating surrounding an exterior of the piezoelectric composite;
- and
- c. a power converter electrically connected to the piezoelectric composite,
- wherein the piezoelectric composite is configured to transmit electrical energy generated by the piezoelectric composite to the power converter.
