Monitoring cellular activity can be done in vivo or in vitro by using an array of planar microelectrodes (MEAs). However, biological systems such as organs are not limited to a 2D geometry. Therefore, there is a need for electrodes to record cellular activity in three dimensions to better visualise 3D cellular networks. In this thesis, 3D MEAs were printed with different conductive inks using two piezoelectric and electrohydrodynamic inkjet printing. As proof-of-principle, the printed 3D electrodes were used to successfully measure cellular activity of cardiomyocyte HL-1 cells.
