      abstract     = {We present a model to describe the response of chip-based
                      nanocavity sensors during extracellular recording of action
                      potentials. These sensors feature microelectrodes which are
                      embedded in liquid-filled cavities. They can be used for the
                      highly localized detection of electrical signals on a chip.
                      We calculate the sensor's impedance and simulate the
                      propagation of action potentials. Subsequently we apply our
                      findings to analyze cell-chip coupling properties. The
                      results are compared to experimental data obtained from
                      cardiomyocyte-like cells. We show that both the impedance
                      and the modeled action potentials fit the experimental data
                      well. Furthermore, we find evidence for a large seal
                      resistance of cardiomyocytes on nanocavity sensors compared
                      to conventional planar recording systems.},
