“…The humidity sensor’s active layer was made of a novel composite of polyethylene oxide (PEO) and 2D molybdenum disulfide (MoS 2 ) flakes, achieving high sensitivity (85 k Omega/%RH) and almost linear responsiveness over a wide detection range (0–80% RH) of relative humidity, As shown in Figure 10 a,b. Chang [ 93 ] introduced a molecular patterning technique with spatial control for spatial control molecular patterning for preparing liquid crystal (LC) microdroplet arrays on glass substrates. This technique utilized an oxygen plasma-activated PDMS stamp to remove pre-coated dimethyloctadecyl[3-(trimethoxysilyl)propyl] ammonium chloride (DMOAP) molecules from the glass substrate, resulting in surfaces with complementary patterns and specific hydrophobicity.…”
