摘要： An actuator is disclosed which includes a piezoelectric bimorph. The actuator also includes a substantially moisture impervious and electrically insulating packaging having a cavity around the birnorph providing for acloarance around the bimorph. The packaging includes a carrier having first and second surfaces and an aperture wherein the bimorph is disposed, the packaging further includes f9st and second cover films selectively attached to the first and second surfaces respectively, and at least one flex circuit connected to the bimorph for supplying electrical energy thereto.

摘要： A high pressure transducer is disclosed. The transducer includes a supply inlet configured to provide a gas supply to the high pressure transducer at a supply pressure and a pressure divider section coupled to the supply inlet. The pressure divider section is configured to reduce the supply pressure to a reduced pressure as a function of a first predetermined ratio. The transducer also includes a low pressure control section coupled to the pressure divider section and configured to receiving the gas supply at the reduced pressure and an amplifying section coupled to the low pressure control section. The low pressure control section varies the reduced pressure to produce a variable control pressure to actuate the amplifying section in response thereto. The amplifying section is also configured to multiply the variable control pressure as a function of a second ratio to obtain an output pressure. Further, the transducer includes a main supply valve coupled to the amplifying section, wherein the amplifying section controls the main supply valve.
