Towards an Embedded Integrated Measurement System for the In Vitro Monitoring of Biomedical Impedance Related to Fibrosis Phenomenon
Résumé
In this article a full wireless integrated measurement system of biomedical impedance is presented with main objective to characterize fibrosis phenomenon using impedance monitoring. It has further scope to make it secure and accurate by transferring measured data wirelessly using a Zigbee protocol This microcontroller-based system acquires the impedance by exciting an electrode and processes data in order to get clear values of real and imaginary data separately. The communication between master and slave is done with I2C protocol. Change in impedance can give a proper idea to reveal an intensity of fibrosis by correlated it to cell abnormal proliferation rate. In this article, as a proof of feasibility, we demonstrate on low and medium range resistors that our system is able to make reliable wireless transfer of impedance data, in accordance with the constraint of future in vitro experiments.
