Debug / finetune and optimize the already existing demonstrator PCB design. Write SW for the measurement subsystems (Imec SoC with ARM-M4 core). Write SW for an SPI data controller for subsystem configuration and data readout. Write PC SW (python) for data collection. Create test setup for simultaneous 16 channel bio-impedance readout on phantom model. Optional: chip/PCB characterization. Optional: EIT image reconstruction.
