Document Type and Number:
WIPO Patent Application WO/2022/210851
Kind Code:
A1
Abstract:
The present disclosure provides a novel ultrasonic probe head that can be used for both linear and convex type probes. An acoustic wave probe head (100) of the present disclosure is a flexible ultrasonic probe head (100) comprising at least an ultrasonic element array base (10) and a planar elastic body (20) for supporting the ultrasonic element array base (10), wherein: the ultrasonic element array base (10) is flexible and includes a plurality of piezoelectric MEMS ultrasonic transducers (1) on a substrate (2); and the ultrasonic element array base (10) is supported along a stress neutral surface (A) that is created when the planar elastic body (20) is bent in the thickness direction along the axis in the direction of arrangement of the array.
