1. Self-folding triangular devices at two scales.
Self-folding triangular devices at two scales. (A) Size comparison of the two devices and the close up view of the electronic components in the larger device. I, II, and III show the circuit parts indicated in Figure 3A. Inductors L1, L2, and L3 (shown in Fig. 3A) are implemented by using two inductors connected in parallel as shown in the inset to increase the current capacity. (B) Top view of the smaller device. (C) Bottom view of the smaller device. Inductors and capacitors are placed at the bottom of the device. The corresponding circuit diagram can be seen in Fig. 3B.
