摘要:
A method for producing a capacitive sensor, comprising steps consisting of: (a) forming trenches (105) in a support (100) made from at least one given material by etching said at least one given material, (b) making said given material porous at the walls and the bottom of the trenches, (c) filling the trenches (105) with a conductive material (110).
摘要:
Pressure sensor suited to measuring low pressures, comprising a body extending in a plane, the said body comprising a measurement zone (6), situated at the end of the body, a connection zone (10) situated at another end of the body, the said measurement zone (6) comprising a cavity (12) delimited by a wall (14) that is deformable under the effect of a difference in pressure between the inside of the cavity and an external environment (E), the said deformable wall (14) being situated at rest in a plane parallel to the plane of the sensor, the said sensor also comprising means of measuring the deformation of the deformable wall (14), the said measurement means being situated in the cavity (12), means of electrical connection connecting the measurement means to the connection zone (10), said means of electrical connection being arranged in the body.
摘要:
The invention relates to a mechanical structure comprising a stack containing an active substrate (10) and at least one actuator (20) suitable for generating vibrations in the region of said active substrate, said stack comprising a basic structure for the amplification of said vibrations (30), arranged between said actuator and said active substrate, the structure being used to transmit and amplify said vibrations; and comprising at least one trench (Ti) arranged between said actuator and said active substrate. The invention also relates to a method for producing said structure, comprising the use of a temporary substrate.
