Add-on unit or cable connectable to the power supply or signal cord of an electric device
The present invention discloses a method for creating spin-affected electric currents passively and feeding them into electric devices. The invention can be realized as either a rectangular black box incorporating coatings on top of and on the bottom of a conducting volume of material, or by coating a round-shaped wire or thread(s) of a cable. This is obtained by using a specific coating material on the conducting piece of material. The material may be piezoelectric, such as silicon dioxide (i.e. quartz) but also silicon carbide (SiC) may be used. Also, mixtures and composite arrangements are possible in order to create a coating. The manufactured add-on unit, when supplied with the input power or input signal, will act as an electron spin feeding device to the electric device because the electrons will be moving strongly within the interface area of the coating and the conducting material with aligned spins. The resulting effect also lasts longer within the electric device than just the time when the add-on unit is connected to the electric device.

The invention relates to a device comprising an electroceramic component (1) having a first area (2) and a second area (3), a potting compound (11) at least partially surrounding the electroceramic component (1), and a sleeve-shaped housing (15) which at least partially surrounds the potting compound (11), the housing (15) having, in a first housing section (15a) which surrounds the potting compound (11) in the first area of the electroceramic component (1), a material wherein the thermal conductivity of said material is greater than the thermal conductivity of a material of the housing (15) in a second housing section (15b), and wherein the housing (15) in the second housing section (15b) surrounding the potting compound (11) in the second area of the electroceramic component (1) comprises a non-conductive material.
Interdigital transducers on a piezoelectric thin-film for signal compression
A piezoelectric thin-film suspended above a carrier substrate. An input interdigital transducer (IDT) having first interdigitated electrodes is disposed at different locations along the horizontal axis and on the first side of the piezoelectric thin-film. Each opposing pair of the first interdigitated electrodes is to selectively transduce a particular frequency range of an input electrical signal that varies in frequency over time into an acoustic wave of a laterally vibrating mode based on a pitch between electrodes of the opposing pair. An output IDT that includes second interdigitated electrodes is disposed at different locations along the horizontal axis and on the second side of the piezoelectric thin-film. Each opposing pair of the second interdigitated electrodes is to convert the acoustic wave transduced by the respective opposing pair of the first interdigitated electrodes into a compressed pulse.
Piezoelectric transformer
A voltage transformer including a beam or membrane made of a first polymer material having a resonance frequency in the range from 1 Hz to 1,000 Hz and including on the beam or membrane a stack successively including: a first electrode; a first piezoelectric layer made of a second polymer material; a second electrode; a second piezoelectric layer made of a third polymer material identical to the second polymer material or different from the second polymer material; and a third electrode.
Damper for power train
A damper for a power train, comprising a piezoelectric transformer and a load element connected across the output of the piezoelectric transformer.
METHOD OF INCREASING ULTRASONIC SIGNAL RECEPTION
A transceiver apparatus for maximizing voltage. A voltage booster or transformer is implemented using piezoelectric thin films in substrates, preferably CMOS substrates where active processing of RF signals can lead to highly integrated and inexpensive ICs. The voltage gain is achieved by cascading multiple transducers, formed in the same piezoelectric thin film, or films cascaded in series on top of each other. An array of transducers are connected in parallel or series, connected to the input or output port electrodes. Other approaches include placing the receive transformer in a location where the diffracting field from the transmitter transducer is incident on the receive transducer generating a higher ultrasonic field at the receive transformer and increasing the voltage is to connect an array of transducers, formed in the same layer, or different layers of piezoelectric layer in parallel in drive mode when the pulse is transmitted.

The differential sensor includes a substrate, an amplifier coupled to the substrate, and a plurality of highly-matched piezoelectric capacitors formed onto the substrate. A first set of the highly-matched piezoelectric capacitors are electrically coupled to a non-inverting input of the amplifier, and a second set of the highly-matched piezoelectric capacitors are electrically coupled to an inverting input of the amplifier to form an open loop differential amplifier.

In at least one illustrative embodiment, a microelectromechanical system (MEMS) includes a composable piezoelectric actuator electrically coupled to a terminal. In response to a voltage applied across electrodes of the actuator, a piezoelectric rod moves from an initial position to a displaced position. In an embodiment, the MEMS includes two terminals, a resistive element is coupled between the terminals, and when in the displaced position the rod contacts one of the terminals. In an embodiment, the MEMS includes three terminals, and when a threshold voltage is applied to one of the terminals, the rod moves to the displaced position and allows current to flow between the other two terminals. In an embodiment, the MEMS includes a primary set of actuators that are mechanically but not electrically connected to a secondary set of actuators. An output terminal is coupled to the second set of actuators. Other embodiments are described and claimed.
Hybrid piezoelectric microresonator
A hybrid ferroelectric/non-ferroelectric piezoelectric microresonator is disclosed. The hybrid microresonator uses a ferroelectric layer as the actuator as ferroelectric materials typically have higher actuation coefficients than non-ferroelectric piezoelectric materials. The hybrid microresonator uses a non-ferroelectric piezoelectric layer as the sensor layer as non-ferroelectric piezoelectric materials typically have higher sensing coefficients than ferroelectric materials. This hybrid microresonator design allows the independent optimization of actuator and sensor materials. This hybrid microresonator design may be used for bulk acoustic wave contour mode resonators, bulk acoustic wave solidly mounted resonators, free-standing bulk acoustic resonators, and piezoelectric transformers.
