Figure 1. Experimental setup and modeling for electrical stimulation bioreactor.

Figure 1

Experimental setup: (A) An electrical stimulator generates the pulses which are transmitted to bioreactors located inside an incubator maintained at 37° C. Bioreactors are in form of modified 60 mm diameter Petri dishes outfitted with electrodes 4 cm in length placed 1 cm apart. 3-D collagen scaffolds are placed in between the electrodes. Modeling of electrical fields in bioreactor at the initiation of a 5V pulse: (B) Top view. (C) Cross-sectional view with traces of pathways between electrodes, where Trace A corresponds to the longest and Trace B corresponds to the shortest distance between the two electrodes. (D) Plot of voltage versus distance from the center of the Petri dish for Trace A (blue) and Trace B (pink).
