Figure 4

Selective stimulation of the arrayed skeletal muscle bundles enclosing PEDOT/PU electrode wires immersed in the same culture medium. (a) Schematic view of the experimental setup. (b) Phase-contrast microscopic view of the arrayed muscle bundles. (c) Time-course of contraction of muscle bundles 1 and 2 stimulated with periodic constant current pulses (0.23 mA amplitude, 10 ms duration, 2.3 μC charge injection, 1 Hz frequency). The arrows below the time course represent the trigger pulses.
