To realize cyborg insects for disaster relief, we introduced a highly flexible and adhesive polymer, SEBS, as a novel adhesive layer for mounting thin-film devices.Compared to conventional ethanol-based adhesives, SEBS significantly improved both the formation rate of the mobility-preserving "stepping-stone structure" and the conductivity retention of the devices. Experiments on Madagascar cockroaches showed that SEBS maintains high conductivity for device thicknesses between 1 and 3 µm. However, a performance drop at 4 µm revealed the thickness limit for conforming to the insect's bending movements.This stable integration prevents performance degradation during severe movement, greatly contributing to the long-term operation and reliable remote control of cyborg insects.
