Composite physical focused energy converter and manufacturing method thereof

Abstract

The invention is suitable for the technical field of focused ultrasound, and discloses a composite physical focused energy converter and a manufacturing method thereof. The energy converter comprisesa housing and a plurality of composite energy conversion units; a plurality of through holes are formed in the front end of the housing; the composite energy conversion units are arranged in the through holes in an inserting manner; the axes of the multiple composite energy conversion units are directed to the same point; and the composite energy conversion units are connected with electrode leads. The manufacturing method is used for manufacturing the previous composite physical focused energy converter. With the adoption of the composite physical focused energy converter and the manufacturing method thereof, the various composite energy conversion units are not required to be subjected to compression forming, so that the situation that a small energy converter is easy to fracture in thepressing process is avoided, the requirements that the weight is low, the size is small, focused focal points are small, and the composite physical focused energy converter is head-mounted are met under the condition that the energy is equivalent, the composite physical focused energy converter is applied to a research of ultrasound stimulation on mouse behaviors, movement behaviors of a mouse arenot affected by the energy converter in the stimulation process, and it is guaranteed that the research is carried out scientifically and advantageously.

Description

technical field [0001] The invention belongs to the technical field of focused ultrasound, and in particular relates to a composite material physically focused transducer and a manufacturing method thereof. Background technique [0002] There are two main types of focused ultrasound probes. One is that the piezoelectric ceramic itself is a curved physical focusing transducer. Its disadvantages are: large volume, heavy weight, thick wire, wearing on the head of the mouse seriously affects the motor behavior of the mouse, and it is better for the transducer not to affect the motor behavior of the mouse during the stimulation process. Therefore, in the energy The quality and volume of the transducer should be as small as possible when it is large enough. The second is the focusing transducer formed by pressing the composite material into an arc shape through a special fixture. It is difficult to press and form when the bending radius is small, especially for low-frequency tr...

Its disadvantages are: large volume, heavy weight, thick wire, wearing on the head of the mouse seriously affects the motor behavior of the mouse, and it is better for the transducer not to affect the motor behavior of the mouse during the stimulation process. Therefore, in the energy The quality and volume of the transducer should be as small as possible when it is large enough

It is difficult to press and form when the bending radius is small, especially for low-frequency transducers. In the case of 0.5MHz, the height of the ceramic column is about 2.3mm. Such a 1-3 composite material should be pressed into a small arc with a bending radius of 5mm. Curved surfaces are very difficult and can easily fracture
