在传感方面，20%的医疗扫描依赖于超声波，用于日益多样化的程序。超声波在水下传感和通信中具有广泛的应用，是无损检测的关键技术之一。超声波设备是每部移动的手机中必不可少的组件，正在开发用于增强生物识别安全性。超声波在能量的远程输送中也很重要。在医学治疗中，它用于治疗神经功能障碍和癌症。许多手术工具都是用超声波驱动的。作为清洁表面和连接互连的最佳方式，超声波在半导体和电子制造中无处不在;它也被探索用于向植入物输送功率并提供非接触式触摸感。如此广泛的应用预示着一个令人兴奋的未来：新材料将出现在应用中;半导体电路将提供更小、更方便的仪器系统;自动化和机器人技术将需要更好的传感器;数据分析将受益于机器学习。

In sensing, 20% of medical scans rely on ultrasonics for increasingly diverse procedures. Ultrasonics is pervasive in underwater sensing and communication and a key technology for non-destructive evaluation. Ultrasonic devices are essential components in every mobile phone and are being developed for enhanced biometric security. Ultrasound is also important in remote delivery of energy. In medical therapy, it is used to treat neural dysfunction and cancer. Many surgical tools are actuated with ultrasound. As the best way to clean surfaces and bond interconnects, ultrasound is pervasive in semiconductor and electronics fabrication; it is also being explored for power delivery to implants and to give a contactless sense of touch. Such a broad range of applications predicts an exciting future: new materials will emerge into applications; semiconductor circuits will deliver smaller, more convenient instrumentation systems; autonomy and robotics will call for better sensors; and data analysis will benefit from machine learning.
