\begin{abstract}
A novel approach towards developing a micro-bubble detection technology
based on using a PZT transducer to induce an acoustic resonance state
within the system under investigation is here presented. The concept,
originally proof-of-concept tested in a cylindrical acoustic resonant
chamber, has proven to be able to detect single microbubbles with
diameters in the range of 390 to 600 \selectlanguage{greek}µ\selectlanguage{english}m in a swine thigh, with either
saline solution or sheep blood as the medium in the bubble guide. It has
shown to be extremely adaptable, capable of accommodating industrial
pipes as well as biological specimens, resilient and extremely energy
efficient, able to detect micro-bubbles with as little as 0.8 mW and
potentially less.%
