20140200681 | Neurotrophic Electrode Neural Interface Employing Quantum Dots - A neural sensor includes a substrate defining an array of vias passing therethrough, a plurality of conductive surfaces, a light source, a plurality of groups of quantum dot-based luminescence units and a charge-coupled device (CCD) array. Each via allows a neurite to grow therethrough. Each conductive surface is adjacent to a different via and is electrically coupled thereto. The light source directs light toward the substrate. Each group of quantum dot-based luminescence units extends upwardly from a different one of the conductive surfaces generates light at a different predetermined wavelength when excited with light from the light source. Each luminescence unit changes its luminescence when electrically stimulated by a neural potential generated by a neurite. The CCD detects luminescence from each of the plurality of groups of quantum dot-based luminescence units and generates a signal representative of intensity of each wavelength of light detected. | 07-17-2014 |
20090281448 | Wireless Skin Surface Potential Sensing System and Method - A sensing apparatus and method allows a patient to control an object by asserting a motor unit action potential. An electromyogram sensor is configured to be placed at a selected location on the patient and to sense a motor unit action potential from the patient. The electromyogram sensor is also configured to generate an EMG signal representative of the motor unit action potential. A personal area network transmitting device that is responsive to the EMG signal is configured to generate a wireless signal that corresponds to the EMG signal. A personal area network receiving device is configured to receive the wireless signal and to convert the wireless signal into an electrical signal. A processor is configured to receive the electrical signal and to generate at least one control signal that has a value corresponding to a state of the electrical signal. | 11-12-2009 |
20080221645 | Neurotrophic Electrode Neural Interface Employing Quantum Dots - A device for interfacing neurons includes a substrate that defines at least one via passing therethrough. The via is configured to allow at least one neurite to grow therethrough. A light generating unit is disposed adjacent to the substrate and is configured to generate light of a predetermined frequency when an action potential from the neurite is sensed. A light sensor that is spaced apart from the substrate is configured to assert a neural signal corresponding to the action potential when the light generating unit generates light of the predetermined frequency. | 09-11-2008 |
