Plane Wave Imaging (PWI) plays a crucial role in the field of medical ultrasound imaging; however, its application scenarios are constrained by the predominant use of rigid probes. This study presents a design and fabrication process of a type of flexible ultrasound transducer suitable for PWI. The process involves attaching specifically shaped PZT-5H thin films to copper electrodes adhered to PDMS material. The linear array comprises 32 individual elements, each with dimensions of 10mm × 1mm × 0.4mm. The average resonance frequency, capacitance, and loss tangent are 7.58 MHz, 1082.2 pF, and 0.018, respectively. Experimental results illustrate the transducer’s flexibility by adhering it to curved surfaces (convex and limb surfaces). Moreover, both single plane-wave and multi-angle plane-wave imaging experiments were conducted using the flexible transducers, demonstrating the feasibility for PWI. With its compact size, flexibility, and portability, the transducers hold potential for long-term non-invasive monitoring applications in the future.
