An integrated nanowire device includes a first array of nanowires having a first set of characteristics and a second array of nanowires having a second set of characteristics. A processor is electrical communication with the first and second arrays of nanowires receives the first plurality of charges and generate a processor signal therefrom. The second array of nanowires may be configured to produce a stimulation current in response to the processor signal. The first or second array may be used to generate power for operation of the device, or the arrays may function as a stimulator, sensor combination to enable the device to self-regulate based on localized responses to stimulation. The device may be implanted for use as a neural stimulator.

Disclosed herein are instruments and methods for delivery of substrates, including cell-seeded substrates, to target tissues requiring treatment for various diseases that induce cell death, damage or loss of function. The substrates are configured to provide cells, including stem cells, with a structural support that allows interconnection with and transmission of biological signals between the cells and the target tissue.

An actuator device that includes at least one fiber, and at least one first coating is disclosed. The first coating encloses the at least one fiber. The actuator device may include a plurality of fibers and/or a conducting material. The coatings may enclose the plurality of fibers, or each individual fiber. The coatings may provide moisture protection, UV protection, saline protection, and oxidation protection. The coating may be thermally and electrically conducting or insulating, depending on the specific function and environment of the actuator device.
