Two dimensional (2D) materials are optimum electronic materials for flexible electronics due to their ultimate thin structures and enriched electrical properties. In this presentation, the potential of 2D transition metal dichalcogenides (TMDCs) as flexible sensing devices willbe discussed from several aspects including the materials and heterostructures synthesis, manufacturing technology, and applications. We will show large scale growth of TMDCs on different substrates, including polymer substrate. We will also demonstrate highly effectivewet-contact printing method to construct hierarchical structure of 2D materials on micro/nanopatterned polymer substrate for better photodetector. Finally, we will demonstrate better strain sensitivity using stacked heterogeneous system (MoSe2/WSe2).
