Micro Bioimpedance Tomography for Continuous Monitoring of Cellular Processes

Electrical impedance tomography (EIT) is an imaging technique which, on a large scale, has been used to visualize and monitor physiological functions. The focus here is make this technique viable for monitoring cellular processes. To this end, an EIT-based sensor system is currently being developed and characterized. Initial testing with the setup allows for detection and location information of a 700 microns glass bead. Current efforts are focusing on increasing the spatial resolution of EIT by employing a greater number of electrodes (16 or 32) and decreasing the size of the probe area.
