Figure 3

(a) Single and (b) crossed 25 \(\upmu \)m diameter gold wire in air and in tension last frame and mean of pre-excitation frames difference image; (c) excitation frame for (a); (d) first and last frame difference image with no excitation pulse; scale bar: 200 \(\upmu \)m. (e) Wire displacement plot against time for the motion shown in (a). (f) pre-excitation frame of a 7 \(\upmu \)m diameter carbon fiber target diagonally suspended in air and in tension in front of a pair of 50 \(\upmu \)m diameter aluminum and 25 \(\upmu \)m diameter gold wires, with the red dashed arrow indicating pre-excitation fiber location; (g)–(i) fiber location displacement over time with the solid blue arrow indicating the current frame fiber location; scale bar: 100 \(\upmu \)m. (j) Fiber displacement plot against time for the motion shown in (g)–(i).
