摘要： Methods and systems for locating a chemical source include cross-correlating chemical concentration data from pairs of positions using a processor to determine an average velocity vector for a group of positions that averages away turbulence contributions. A convergence region is determined based on multiple average velocity vectors to determine a chemical source location.

摘要： A piezoelectronic switch device for radio frequency (RF) applications includes a piezoelectric (PE) material layer and a piezoresistive (PR) material layer separated from one another by at least one electrode, wherein an electrical resistance of the PR material layer is dependent upon an applied voltage across the PE material layer by way of an applied pressure to the PR material layer by the PE material layer; and a conductive, high yield material (C-HYM) comprising a housing that surrounds the PE material layer, the PR material layer and the at least one electrode, the C-HYM configured to mechanically transmit a displacement of the PE material layer to the PR material layer such that applied voltage across the PE material layer causes an expansion thereof and an increase the applied pressure to the PR material layer, thereby causing a decrease in the electrical resistance of the PR material layer.

摘要： A piezoelectronic transistor device includes a first piezoelectric (PE) layer, a second PE layer, and a piezoresistive (PR) layer arranged in a stacked configuration, wherein an electrical resistance of the PR layer is dependent upon an applied voltage across the first and second PE layers by an applied pressure to the PR layer by the first and second PE layers. A piezoelectronic logic device includes a first and second piezoelectric transistor (PET), wherein the first and second PE layers of the first PET have a smaller cross sectional area than those of the second PET, such that a voltage drop across the PE layers of the first PET creates a first pressure in the PR layer of the first PET that is smaller than a second pressure in the PR layer of the second PET created by the same voltage drop across the PE layers of the second PET.
