摘要： Method for increasing the ability of at least one droplet to slide over a medium. An ultrasonic surface wave is generated in the medium with a sufficient amplitude to cause the droplet to deform in an inertio-capillary eigen-vibration mode, thus decreasing the attachment of the droplet to the medium, so as to make it easier for the droplet to move under the effect of an external force, the amplitude of the ultrasonic surface wave being insufficient to cause the droplet to deform asymmetrically to the point that it moves in the absence of the external force in the direction of propagation of the ultrasonic surface wave.

摘要： An integrated photoacoustic transducer, sensing system and method for assisting in sensing a concentration of a species in a fluid such that the integrated photoacoustic transducer includes a waveguide structure. The waveguide structure has an optical resonance spectrally overlapping a spectral absorption line or band of the species. The photoacoustic transducer includes at least one acoustic cavity formed in a portion of the waveguide structure and configured for receiving the fluid for sensing comprising the species. The at least one acoustic cavity has an acoustic resonance spectrally overlapping with a harmonic of a modulation frequency. At least one acoustic transducer comprising a deformable mechanical portion is included in the photoacoustic transducer. The deformable mechanical portion is in direct acoustic communication with the at least one acoustic cavity and has an adjustable mechanical resonance, which can be brought into spectral overlap with an acoustic resonance of the least one acoustic cavity.

摘要： A method for generating at least one tactile pattern using a haptic feedback device (70) having an active space within which a user can move his finger (F) in order to feel the tactile pattern, the perception of the pattern being caused by the modulation of the mechanical excitation of the finger pad by an excitation element, the method having the steps involving: detecting (100) the position of the finger (F) in the active space; calculating (101) the speed of the finger, determining (102), for each detected position of the finger, an associated taxtel within a predefined grid of taxtels, each taxtel having an associated texture value that is dependent on the tactile pattern to be reproduced, each taxtel having its largest dimension less than or equal to 8 mm, generating (103, 104, 105), on the basis of the texture value associated with this taxtel, a control signal for controlling the excitation element, this excitation signal being dependent on the speed of the finger at least for the densest tactile patterns to be reproduced.

摘要： A method for generating a flow of fluid, implemented in a device including a membrane (2) provided with at least one hole (20) and elements (4) generating back-and-forth movements, wherein a flow is generated through the membrane by actuating the membrane, at least in the region of the at least one hole (20), according to a mode of deformation of the at least one hole, causing the at least one hole to open and close and disturbing the fluid in order to generate the flow. The device suitable for implementing the method is also described.
