Abstract: Abstract Reduction of power consumption is the key target for modern electronic devices. To this end, a lot of attention is paid to zero-static power switches, being able to change their state between highly resistive and highly conductive and remain in this state even in the absence of external voltage. Still, the implementation of such switches is slow because of compatibility issues of new materials with CMOS technology. At the same time, printable technology enables low-cost processes at ambient temperature and integration of devices onto flexible substrates. Here we demonstrate that printed Ag/MoS2/Ag heterostructures can be used as zero-static power switches in radiofrequency/microwave spectrum and fully-integrated reconfigurable metasurfaces. Combined with graphene, our printed platform enables reconfigurable metasurface for electromagnetic wave manipulation and control for wireless communications, sensing, and holography. In addition, it is also demonstrated that the localised MoS2 phase change may have promoted Ag diffusion in forming conductive filaments.
