PIEZOELECTRONIC SWITCH DEVICE FOR RF APPLICATIONS

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.
