      abstract     = {Inkjet printing is an attractive method for cost-effective
                      additive manufacturing of electronic devices. Especially for
                      applications where disposable sensor systems are of
                      interest, it is a promising tool since it enables the
                      production of low-cost and flexible devices. In this work,
                      we report the fabrication of a disposable microelectrode
                      array (MEA) using solely inkjet printing technology. The
                      MEAs were fabricated with two different functional inks, a
                      self-made gold ink to print conductive feedlines and
                      electrodes and a polymer-based ink to add a dielectric layer
                      for insulation of the feedlines. We printed different MEA
                      designs of up to 64 electrodes with a minimum lateral
                      spacing of 200 μm and a minimum electrode diameter of ~31
                      μm. As a proof-of-concept, extracellular recordings of
                      action potentials from cardiomyocyte-like HL-1 cells were
                      performed using the all-printed devices. Furthermore, we
                      stimulated the cells during the recordings with
                      noradrenaline, which led to an increase in the recorded
                      beating frequency of the cells. The results demonstrate the
                      feasibility of inkjet printing gold MEAs for cell-based
                      bioelectronics.},
