一个简洁的背景解释为什么，最初，科学界和工业界都对生物组织中非线性波传播的存在持怀疑态度，并给出了一种足够宽的压电聚合物水听器探头的设计，这种探头最终被用来验证1-将讨论用于诊断超声成像的5 MHz探测波在组织中经历非线性失真并产生谐波。将审查压电PVDF聚合物材料的出现的深远影响，并介绍美国食品和药物管理局（FDA）和国际电工委员会（IEC）等监管机构在超声计量方面的进展。这些进展包括：发展了水听器绝对校准技术，沿着发展了空间平均校正方法，最高可达100 MHz;发展了利用声光传感器的“点接收器”水听器探头。接下来，将简要讨论非线性超声（NLU）的选定治疗应用，包括碎石机。此外，还将提到使用冲击波作为疼痛缓解工具和减少青霉素抗性细菌，这些细菌形成岩石般坚硬的“生物膜”，可以被有限振幅波粉碎。NLU在化妆品行业中的应用越来越多，它用于重新分配和减少体内脂肪组织，将简要回顾，最后，还将指出零售和娱乐行业中NLU应用的选定示例。
A succinct background explaining why, initially, both the scientific community and industry were skeptical about the existence of the nonlinear (NL) wave propagation in tissue will be given and the design of an adequately wideband piezoelectric polymer hydrophone probe that was eventually used to verify that the 1–5 MHz probing wave then used in diagnostic ultrasound imaging was undergoing nonlinear distortion and generated harmonics in tissue will be discussed. The far-reaching implications of the advent of the piezoelectric PVDF polymer material will be reviewed and the advances in ultrasound metrology prompted by the regulatory agencies such as US Food and Drug Administration (FDA) and International Electrotechnical Commission (IEC) will be presented. These advances include the development of absolute calibration techniques for hydrophones along with the methods of accounting for spatial averaging corrections up to 100 MHz and the development of “point-receiver” hydrophone probes utilizing acousto-optic sensors. Next, selected therapeutic applications of nonlinear ultrasonics (NLU), including lithotripters will be briefly discussed. Also, the use of shock waves as pain relief tool and in abating penicillin resistant bacteria that develop rock hard “biofilm” that can be shattered by the finite amplitude wave will also be mentioned. The growing applications of NLU in cosmetic industry where it is used for redistribution and reduction of fatty tissue within the body will be briefly reviewed, and, finally, selected examples of NLU applications in retail and entertainment industry will also be pointed out.
