Abstract: A low-voltage microfluidic valve device and system for regulating the flow of fluid. One low-voltage microfluidic valve device for regulating the low of fluid includes a nano-textured dendritic metallic filament configured to grow and retract in response to a voltage. The low-voltage microfluidic valve device also includes a microfluidic channel configured to allow fluid flow, wherein the fluid flow is selectively interrupted by the growth of the nano-textured dendritic metallic filament. The low-voltage microfluidic valve device also includes a membrane positioned proximate to the fluid and configured to alter shape in response to the growth of the nano-textured dendritic metallic filament.

Abstract: ElectroCorticoGraphy (ECoG) sensors and uses are disclosed. These ECoG arrays, systems, and processes may be operable or configured to: i) simultaneously record neural signals while providing stimulation on specific portions of the cortex using a user-guided stimulator; ii) acquire neural signals over a large cortex area; iii) provide individual or group stimulation while concurrently receiving neural feedback; and/or iv) acquire neural signals at a setting remote from the neural source using wireless or other communication techniques.

Abstract: Systems, devices, and methods involving cardiac pace making are provided. Implantable wireless pace making systems, devices, and methods using electromagnetic waveforms to interact with subcutaneous implanted sensors or stimulators, or both, are described. Systems, devices, and methods can include wireless, miniaturized, battery-free, radiofrequency (RF) microwave activated, sensors or stimulators or integrated sensor/stimulators that are implanted in multiple thoracic cavity locations, and interact with a remote pace making control-module or multiple modules.
