Impedancellmeter aims to provide a device for the characterization of microelectrodes of neural implants used for functional rehabilitation. This project is based on the impedancemetry technique.
To quantify the electrode impedance, Impedancellmeter is based on various electronic stages and an MSP432P401R board from Texas Instruments. Thanks to an oscillator (AD9833), our system emits a sinusoidal signal varying in frequency which is applied to a biological tissue. The signal is then received by an analog-to-digital converter. This allows a series of mathematical operations to be applied to the signal in order to calculate the impedance. The measurements made are sent via bluetooth (BLE) to a graphical user interface in order to visualize the data. The state of health of a tissue can be analyzed thanks to these graphs.
