Characterization of physical parameters of viscoelastic media has become interesting according security norms and requirement quality, particularly in pharmaceutical, cosmetic and food industries whose development process of the final product goes through several stages of thermal and mechanical stresses. Obtaining continuous measurements is often more difficult and only a few constraining devices allow continuous monitoring of the bio-physical, physic-chemical properties of evolving matter. The development of a new autonomous ultrasound capsule-based scanning method associated with viscoelastic complex media represents a very important challenge given the difficulty of experimental implementation in the low frequency band. This work aimed to obtain conclusive results to assess exposure compared to the thresholds tolerated normatively and to propose an alternative method in order to set a better soft diagnosis to avoid in the limit of possible exposure regarding the harmful radiation. In this work a spherical device (1 cm diameter) has been developed as an acoustic sensorwith a resonance fundamental frequency of 32 kHz. Its spherical shaped geometry composed of two hemispherical shells assembled together allows it to incorporate both the active element (piezoelectric ring) and the embedded electronics dedicated to scheduling function. Using such architecture; this “capsule” can simultaneously manage tasks such as acoustic transmission/reception, remote data storage and/or telecommunication, as well as provide extended autonomy, which is currently not available for discrete elements. Given the technical characteristics of such resonators, the randomly distributed capsule network will be able to deliver useful information regarding the evolution of the mechanical state of a dynamic system favoring an application on the following of matter in industrial mixers.
