Owing to the excellent mechanical adaptability to curved surfaces and high circuit flexibility, conformal electronics have been developed for extensive applications including aeronautics and wearable electronics. However, conventional methods for fabricating conformal circuits are often constrained by planar structures, limiting the design flexibility and applicability of electronic devices on more complex and varied surfaces.

Description of SMPs The SMPs used here are thermoset SMPs with reconfigurability of permanent shapes, with which we can effectively adapt the permanent shape of the SMP according to the mold51,52,53. The molecular structure and polymer network of the two kinds of SMPs involved are shown in Supplementary Fig. 2. SMP1 and SMP2 have similar structures, but the molecular weights of polycaprolactone diol (PCL) in SMP1 and SMP2 are different.
