Abstract
ZnO UV photodetector (PD) arrays based on paper using screen printed methods and Miura-origami (Miura-ori) technology exhibit ultra-high stretchable (strain: up to 1000%), bendable (bending angle: >30°) and twistable (twist angle: up to 360°) properties. Compared to under high strain (>500%), the AOI-dependent variation of PDCR is small (from -20% to -40%) under low strain (from 0% to 500%) even at the largest angle of incidence (85°), showing the ultra-high omnidirectional property. Moreover, ultra-stable performance of paper-based ZnO UV PD arrays with Miura-ori structures was measured even after 400-cycle stretching, bending and twisting processes, respectively, showing the outstanding capability for various practical conditions such as different size of light sources, various curve and uneven surfaces. Via the fusion of paper substrates, origami methods and ZnO UV PD unite cells, the strategy described here opens avenues to develop paper-based PDs with low-cost for the next-generation deformable optoelectronic applications.
