Provided are a pressure difference sensor, and a manufacturing method and an application thereof. A manner of bonding three layers of wafers is adopted, and the sensor includes an upper structure, an intermediate structure and a lower structure. Each of the upper structure and the intermediate structure is manufactured by a silicon-on-insulator (SOI) wafer, the lower structure is manufactured by patterned doped intrinsic silicon; and a lead pad of each of the upper electrode, and the intermediate electrode and the lower electrode is located on a corresponding one of three-stepped steps at a side of the pressure difference sensor. Annular through holes are formed around the upper electrode and the lower electrode. A constant capacitance of a capacitance signal outputted by an upper capacitor of the sensor by extending an electric field line path of the constant capacitor part.

Provided are an identifier resolution method and apparatus for the Internet of Things. In the method, different identifier resolution systems are compatible through constructing an identifier resolution architecture for the Internet of Things, and a unified method is used for resolving various identifiers. Therefore, it is simply required to maintain one identifier resolution architecture for the Internet of Things when resolving different identifiers, which reduces the workload and difficulty for maintenance of the identifier resolution system and thus reduces the workload and difficulty for maintenance of the Internet of Things.
