Electrical impedance tomography in on-chip integrated microtubular fluidic channels

A tubular electrical impedance tomograph (EIT) with micrometric dimensions was fabricated by using rolledup nanotechnology. This approach gives access to EIT devices with tunable sizes in the sub-100 µm range. EIT images of silicon dioxide microparticles were obtained as proof of principle. These devices could enable the impedimetric analysis of biological micro-scale objects, such as single cells or small cell clusters.
