    摘要: Tactile sensors are disclosed that mimic the human fingertip and its touch receptors. The mechanical components are similar to a fingertip, with a rigid core surrounded by a weakly conductive fluid contained within an elastomeric skin. The deformable properties of the finger pad can be used as part of a transduction process. Multiple electrodes can be mounted on the surface of the rigid core and connected to impedance measuring circuitry within the core. External forces deform the fluid path around the electrodes, resulting in a distributed pattern of impedance changes containing information about those forces and the objects that applied them. Strategies are described for extracting features related to the mechanical inputs and using this information for reflexive grip control. Controlling grip force in a prosthetic having sensory feedback information is described. Techniques are described for enhancing the useful force range for impedance sensors by internally texturing the elastomeric skin.

    摘要: Coatings for stents that include a polymer and a drug are provided. The stent's struts are generally linear segments interrupted by a curved or bent segment that contain a drug/polymer coating wherein the concentration of the drug in the coating is greater in at least a portion of the curved or bent segment as compared to the linear segments.

    摘要: A stent is provided with a coating having a variable drug release rate. The release rate can be greater over a curved or bent segment of a strut network as compared to generally linear segments of the strut network. The coating can have a barrier region that is thicker over the generally linear segments. The coating can have a drug mixed with polymers. The curved or bent segment can have a greater amount of a polymer having relatively high drug permeability as compared to the generally linear segments.
