由于材料科学和制造技术的快速发展,可穿戴设备最近在生物医学应用中受到越来越多的关注,特别是在医学超声成像中,传感,和治疗。超声由于其非侵入性,在生物医学应用中无处不在,非离子辐射,高精度,和实时能力。虽然传统的超声换能器是刚性和笨重的,柔性换能器可以顺应弯曲的身体区域以用于连续感测而不限制组织移动或换能器移位。本文综合评述了柔性超声换能器在生物医学成像领域的应用,传感,和治疗。首先,我们回顾了柔性超声换能器的背景。在此之后,我们讨论了柔性超声换能器的先进材料和制造技术及其启用技术状况。最后,我们强调并总结了一些有希望的初步数据,以及柔性超声换能器在生物医学成像中的最新应用,传感,和治疗。我们还提供技术壁垒,挑战,以及进一步研究和开发的未来前景。
Due to the rapid developments in materials science and fabrication techniques, wearable devices have recently received increased attention for biomedical applications, particularly in medical ultrasound (US) imaging, sensing, and therapy. US is ubiquitous in biomedical applications because of its noninvasive nature, nonionic radiating, high precision, and real-time capabilities. While conventional US
transducers are rigid and bulky, flexible
transducers can be conformed to curved body areas for continuous sensing without restricting tissue movement or transducer shifting. This article comprehensively reviews the application of flexible US
transducers in the field of biomedical imaging, sensing, and therapy. First, we
review the background of flexible US
transducers. Following that, we discuss advanced materials and fabrication techniques for flexible US
transducers and their enabling technology status. Finally, we highlight and summarize some promising preliminary data with recent applications of flexible US
transducers in biomedical imaging, sensing, and therapy. We also provide technical barriers, challenges, and future perspectives for further research and development.
