35results about How to "Efficient localization" patented technology

A directional brain stimulation lead assembly provides a lead body and an insulating member defining one or more windows that selectively expose portions of electrodes carried by the lead body to produce a directional stimulation current field. The lead assembly can achieve more effective localization of electrical stimulation to very small brain targets, and thereby reduce the incidence of material side effects caused by collateral stimulation of brain tissue adjoining a desired brain target. In addition, the directional lead can sense brain activity on a more localized basis.

The present disclosure provides a two-dimensional material detector with an asymmetrically integrated optical microstrip antenna, structurally including a metal reflecting surface, a dielectric spacer layer, a two-dimensional active material layer, a top source electrode, and a drain electrode integrated with a metal strip array. Self-driven photoresponse of a metal / two-dimensional material / metal structure is induced by a Schottky junction formed due to contact between the two-dimensional material and the metal. The asymmetrically integrated optical microstrip antennas break the symmetry between the two contact / two-dimensional material junctions. Light absorption in the contact / two-dimensional material junction integrated with optical patch antennas is significantly enhanced by efficient light in-coupling and intensified light localization; meanwhile, the extended boundary of the contact / two-dimensional material junction enlarges the photocurrent collection area. The light absorption in the other contact / two-dimensional material junction is significantly inhibited by a metal bottom surface which is very close to the two-dimensional material.
