Ultrasound vibration potential (UVP) is an electroacoustic phenomenon due to ultrasound applied to the colloid particles and ionic electrolyte. Particles/ions in electrolyte carry electrical charges. When excited, charged particles/ions vibrated and generate a secondary electric field that produces the so-called ultrasound vibration potential comprising two categories of Colloid vibration potential (CVP), or Ion vibration potential (IVP). They are functions of the physiochemical features of particles or ions in the colloid along the path of the ultrasound beam. The present research focuses on understanding of ultrasound vibration potential distribution (UVPD) in a 3-dimensional object for sensor optimisation. A mock body made from Agar and associated experimental methods (Leeds standard III) were established for the purpose of tissue imaging. A new disc-dipole model is developed to address the UVPD inside the mock body and reveal the optimisation sensor set-up. . The sensing device with electrodes nonintrusive set outside the mock body successfully received signals from agar samples, containing either ionic or Nano-particular spics, embedded inside the mock body, providing the physiochemical property of these samples. The signals are either a function of atomic mass or particle size in respect to the physiochemical characterizations of ionic spics and Nano-particles. This work provides a new method based on ultrasound technology and demonstrated a high potential to develop a new measurement and imaging technology for online charactering physiochemical properties of colloids in engineering and complimentary imaging in medicine.
