摘要： A temperature-controlled RF resonator. The resonator includes an insulating thermal enclosure within which are implemented: at least one resonant element configured to deliver an RF output signal when supplied with an RF input signal; at least one heating element configured to supply thermal energy within the thermal enclosure when the at least one heating element is powered by an LF electric power signal; and at least one temperature sensor configured to deliver an LF electric measurement signal as a function of the temperature inside the thermal enclosure. Such an RF resonator has at least one input/output port crossing the insulating thermal enclosure and propagating at least: one signal from among the RF signals; and another signal from among the LF electric signals.

摘要： The invention relates to a piezoelectric device comprising flexible single crystalline piezoelectric LiNbO3 and/or LiTaO3 films integrated on flexible substrate and methods for producing the same. More specifically, the invention relates to a flexible piezoelectric device for energy harvesting. The a Flexible piezoelectric device comprises a flexible substrate layer which comprises an upper face and a lower face, and at least one LiNbO3 and/or LiTaO3 film, called LNT film bonded to one of the faces of the flexible substrate layer, wherein thickness tf of said at least one LNT film is chosen between a use range of 5 to 50 micrometers (μm).

摘要： A method and a device for controlling the propagation of acoustic waves in the vicinity of a wall, the method and device implementing a master device for controlling a set Nc of cells primarily made up of a speaker, a set of Nm microphones connected to the speaker, and a control unit, by means of control laws that determine the intensity of the electrical signal that must be sent to each speaker so as to obtain a target determined generalized acoustic impedance for each speaker, such that a fraction of the acoustic waves is absorbed by the membrane of each speaker.
