Measurement of Mechatronic Property of Biological Gel with Micro-Vibrating Electrode

A new methodology to measure local mechatronic property of biological gel has been proposed, and measurement system has been designed with a micro-vibrating electrode. The designed system consists of two electrodes, where one of the electrodes vibrates with piezoelectric actuator. The component of variation at impedance between two electrodes with vibration of electrode is analyzed at the corresponding spectrum. The system was applied to measurement of impedance in saline solution and potassium chloride aqueous solution. The experimental results show that the component increases with amplitude of vibration of the electrode and with the impedance of solution.
