Abstract: A flexible ultrasound transducer according to an embodiment of the present disclosure includes a substrate having a central part and a plurality of extended parts extending from the central part; an ultrasound probe disposed at the central part of the substrate to acquire an ultrasound image of a region of interest; and a focused ultrasound output unit disposed at the extended parts of the substrate to output a focused ultrasound to the region of interest, wherein the focused ultrasound output unit disposed at the extended parts of the substrate has a flexible property and is deformable. According to the structure of an embodiment, it is possible to simultaneously achieve ultrasound imaging and ultrasonic therapy such as lesion stimulation or removal through focused ultrasound, and adjust the focal position of focused ultrasound or improve the focal sensitivity through flexible movement.

Abstract: Disclosed is a method for manufacturing a high-density neural probe including needles having various forms. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.
