a OM images of patterned IOP sensors (scale bar, 200 μm). b Photo-image of an IOP sensor embedded into a smart contact lens (scale bar, 6 mm). c OM image of an integrated IOP sensor and wireless circuits (scale bar, 600 μm). The relative resistance change of IOP sensors with d different substrate thicknesses (n = 3 independent experiments) and e coating times and designs (n = 3 independent experiments). f Five different measurements of relative resistance with increasing IOP by using a single IOP sensor (n = 5 independent experiments). d–f Data are presented as a mean value ± SD.
