A bimorph transducer was proposed to improve the detection sensitivity and imaging depth of photoacoustic and ultrasound (PAUS) dermoscope. By applying the bimorph transducer, the imaging depth and sensitivity of PAUS dermoscope were enhanced by simultaneously improving excitation efficiency and reception bandwidth. The integrated design of the imaging head of the dermoscope makes it highly convenient for detecting human skin. The PAUS imaging performance was demonstrated via visualizing subcutaneous tumor and depicting full structures of different skin layers from epidermis to subcutaneous tissue. The results confirm that the dermoscope with the bimorph transducer is well suited for PA and US dual‐modality imaging, which can provide multi‐information for skin disease.

通过使用双压电晶片换能器，具有高灵敏度和穿透深度的光声和超声（PAUS）皮肤镜。

提出了一种双压电晶片换能器，以提高光声和超声（PAUS）皮肤镜的检测灵敏度和成像深度。通过应用双压电晶片换能器，同时提高了激励效率和接收带宽，增强了PAUS皮肤镜的成像深度和灵敏度。皮肤镜成像头的集成设计使其非常易于检测人体皮肤。通过可视化皮下肿瘤并描绘了从表皮到皮下组织的不同皮肤层的完整结构，证明了PAUS成像性能。结果证实，带双压电晶片换能器的皮肤镜非常适用于PA和US双模态成像，可以为皮肤疾病提供多种信息。
