    Abstract: A sensor for detecting a target matter includes a chemical sensitive layer that is operable to react when exposed to the target matter and a piezoresistive material coupled to the chemical sensitive layer. The chemical sensitive layer is configured such that the reaction of the target matter with the chemical sensitive layer creates an interfacial tension at the interface of the chemical sensitive layer and the piezoresistive material that changes the electrical resistance of the piezoresistive material. However, the chemical sensitive layer is configured such that the reaction of the target matter with the chemical sensitive layer does not affect the bulk properties of the chemical sensitive layer enough to change the electrical resistance of the piezoresistive material. The sensor also includes an electrical circuit coupled to the piezoresistive material that is operable to detect the change in the electrical resistance of the piezoresistive material due to the interfacial tension.

    Abstract: Microbolometer infrared detector elements that may be formed and implemented by varying type/s of precursors used to form amorphous silicon-based microbolometer membrane material/s and/or by varying composition of the final amorphous silicon-based microbolometer membrane material/s (e.g., by adjusting alloy composition) to vary the material properties such as activation energy and carrier mobility. The amorphous silicon-based microbolometer membrane material/s materials may include varying amounts of one or more additional and optional materials, including hydrogen, fluorine, germanium, n-type dopants and p-type dopants.

    Abstract: Systems and methods for solder bonding that employ an equilibrium solidification process in which the solder is solidified by dissolving and alloying metals that raise the melting point temperature of the solder. Two or more structure surfaces may be solder bonded, for example, by employing heating to melt the solder and holding the couple at a temperature above the initial solder melting point of the solder until interdiffusion reduces the volume fraction of liquid so as to form a solid bond between surfaces before cooling to below the initial melting point of the solder.
