Abstract: Method and apparatus for determining that a pressure field is applied on a structure. A plurality of acoustic waves are generated within the structure using at least one wave generator and a plurality of measurements of the acoustic waves is taken using at least one wave sensor. A pressure field applied to a surface of the structure is determined by processing at least two of the plurality of measurements. The wave generator and the wave sensor may be piezoelectric elements, which may alternate between acting as the wave generator and the wave sensor. Processing the measurements may comprise obtaining a differential measurement value and comparing the value to a threshold. Determining that the pressure field is applied may comprise processing the measurements using a model based on acoustic wave propagation or experimental results. The processing may provide a mapping of the pressure field of an object on the structure.

Abstract translation: 用于确定在结构上施加压力场的方法和装置。 使用至少一个波发生器在结构内产生多个声波，并且使用至少一个波传感器采用声波的多个测量。 通过处理多个测量中的至少两个来确定施加到结构的表面的压力场。 波发生器和波传感器可以是压电元件，其可以作为波发生器和波传感器之间交替。 处理测量可以包括获得差分测量值并将该值与阈值进行比较。 确定压力场的应用可以包括使用基于声波传播或实验结果的模型处理测量。 处理可以提供对象在结构上的压力场的映射。
