The aim of this study is to asist in the measurement of blood glucose concentration in an in-vitro medium by using the photoacoustic method. The tissue was mimicked with gel phantoms and different glucose concentrations were added. The sample which was in the setup was illuminated by a pulsed based laser. The acoustic vibrations that arose in the phantom medium were detected via electret microphone and processed with an electronical circuit and then recorded. When the results were evaluated, there was a correlation with glucose concentration proportions and with the photoacoustic signal amplitudes. © 2015 IEEE.
