摘要： A transdermal micro -patch (1) for use with living tissue (19) is provided. The micro -patch (1) includes a first membrane (9), a reservoir (3), a micro -pump (4), flextensional transducers (2), a microelectronics circuit (5), and an optional sensor (27). The first membrane (9) is permeable to allow the passage of fluid (1 8) in either a unidirectional or bidirectional fashion. The reservoir (3) is a container -like element capable of storing a fluid (19) removed from or communicated into the tissue (19). The micro -pump (4) facilitates transport of the fluid (1 8) between the reservoir (3) and first membrane (9). The flextensional transducers (2) generate ultrasonic waves (15) which are separately communicated into the tissue (19) to transport fluid (18) between the first membrane (9) and tissue (19). Ultrasonic waves (15) could interact to enhance the performance of the micro-patch (1). The microelectronics circuit (5) controls both flextensional transducers (2) and the micro -pump (4). The sensor (27) could be embedded within the micro -patch (1) to monitor temperature, pressure, or flow rate so as to avoid damage or irritation to the tissue (19).

摘要： A system for converting kinetic wave energy from a dynamic fluid into electrical power, the system including a structural housing containing a piezokinetic assembly having a plurality of electromechanical coupled elements, and a dynamic assembly, coupled to the piezokinetic assembly; and charge storage devices or power consumption devices in an electronics module coupled to the piezokinetic assembly. When the exposed to the dynamic fluid medium, the dynamic fluid medium's wave energy couples with the structural housing causing a resulting displacement of the dynamic assembly contained therein.

摘要： The present invention is directed to a piezoelectric transformer based power converter that exhibits efficient operating point tracking ability while providing output regulation by means of simultaneous two-parameter control of the converter power stage. A regulation control stage provides the power stage a regulation control signal indicative of the difference between the measured output parameter and a set-point reference, therefore continuously controlling the gain of the converter to result in a stabilized, regulated output. Additionally, a frequency control stage simultaneously provides the power stage with a frequency control signal correlative to the difference between the current and desired operating points of the piezoelectric transformer. The power stage then translates the frequency control signal into an adjustment to the operational frequency of the input signal to the piezoelectric transformer, as to continuously drive the operating point to the desired position.
