Ultrasound vibration potential (UVP) is an electric signal generated from the vibration of particles or ions along with the trajectory of the ultrasound pulses travelling through a colloidal suspension or ionic electrolyte. Therefore, it may be used to characterize or image the physiochemical property of particles or ions. This paper presents a modelling method based on the principle of static charged disc dipole and its equivalent circuit to model the ultrasound vibration potential distribution (UVPD) inside domains of interest. A tissue-like testing phantom (in 82 × 56 × 66 mm) embedded with one or more sample cells made from either agar or colloids with two electrodes fitted at optimized locations outside of the phantom is reported. The UVP measurements in peak-to-peak amplitude of 162/309 μV and 419/499 μV are measured from two interfaces of a single cell setting with either KCL (1 M) or nanoparticles (SiO2 in 21 nm, 1wt %) mixed with agar. Results from the measurement comply with the modelling of UVPD. The experimental results are evidenced from the relative changes of normalised UVP signals from setting up six interfaces of three cells. The results demonstrate the feasibility of using the static electricity modelling method to estimate UVPD. This implies the potential of UVP for medicine and engineering.

超声振动电势（UVP）是由颗粒或离子的振动以及通过胶体悬浮液或离子电解质传播的超声脉冲的轨迹产生的电信号。因此，它可用于表征或成像颗粒或离子的物理化学性质。本文提出了一种基于静电荷圆盘偶极子原理及其等效电路的建模方法，以对目标域内的超声振动势分布（UVPD）进行建模。据报道，组织样测试模体（尺寸为82×56×66 mm）内嵌有一个或多个由琼脂或胶体制成的样品池，两个电极安装在模体的最佳位置。UVP测量的峰峰值幅度为162/309μV和419/499μV，是通过将单个单元格设置的两个界面与KCL（1 M）或纳米颗粒（SiO2 in 21 nm，1wt％）与琼脂 测量结果符合UVPD的建模。通过建立三个细胞的六个界面，归一化的UVP信号的相对变化证明了实验结果。结果证明了使用静电建模方法估算UVPD的可行性。这意味着UVP在医学和工程领域的潜力。通过建立三个细胞的六个界面，归一化的UVP信号的相对变化证明了实验结果。结果证明了使用静电建模方法估算UVPD的可行性。这意味着UVP在医学和工程领域的潜力。通过建立三个细胞的六个界面，归一化的UVP信号的相对变化证明了实验结果。结果证明了使用静电建模方法估算UVPD的可行性。这意味着UVP在医学和工程领域的潜力。
