Fig. 7: Transition waves in arrays of shells with tunable energy landscape.
From: Universally bistable shells with nonzero Gaussian curvature for two-way transition waves
a, b Arrays of 12 double shells, where a charged tunable shell is placed between the 6th and 7th shell of the array. c, d Experimental pole displacement histories for each shell in the array upon propagation of a transition waves initiated by supplying Δp = 69 kPa of pressure for 100 ms. Vertical black arrows point to the shell number and location of the charged tunable shell in the array.
