... voltage ϕ = 0.225. This is within region B shown in Fig. 6 . The pulse creates sufficiently large dynamic stretches that a cycle of inter-equilibrium vibration occurs (see Figs. 7( a ) and 7( b ) ) before the membrane settles to the large-stretch equilibrium. The dynamic stretches that result cause...
