摘要： Various embodiments of a pressure sensor assembly and an implantable medical device that includes such assembly are disclosed. The assembly includes a substrate having a via that extends through the substrate along a via axis between a first major surface and a second major surface of the substrate, a membrane disposed on the first major surface of the substrate and over the via, and a patterned metal layer disposed on a first major surface of the membrane, a portion of such layer including a first capacitor plate. The assembly further includes an integrated circuit disposed adjacent to the first major surface of the membrane and electrically connected to the metal layer. The integrated circuit includes a second capacitor plate disposed on or within a substrate of the integrated circuit. The first capacitor plate and the second capacitor plate form a variable capacitor disposed along the via axis.

摘要： Various embodiments of a nuclear radiation particle power converter and method of forming such power converter are disclosed. In one or more embodiments, the power converter can include first and second electrodes, a three-dimensional current collector disposed between the first and second electrodes and electrically coupled to the first electrode, and a charge carrier separator disposed on at least a portion of a surface of the three-dimensional current collector. The power converter can also include a hole conductor layer disposed on at least a portion of the charge carrier separator and electrically coupled to the second electrode, and nuclear radiation-emitting material disposed such that at least one nuclear radiation particle emitted by the nuclear radiation-emitting material is incident upon the charge carrier separator.

摘要： Various embodiments of a hermetic assembly and a method of forming such assembly are disclosed. The hermetic assembly includes a dielectric substrate having a first major surface and a second major surface, a patterned layer connected to the first major surface of the dielectric substrate by a laser bond, and a ferrule having a body and a flange extending from the body. The flange is welded to a welding portion of the patterned layer that is disposed between the flange and the first major surface of the dielectric substrate such that the ferrule is hermetically sealed to the dielectric substrate.
