DOI: 10.1364/ol.476637
Abstract: A sensitivity-enhanced optical pressure sensor based on molybdenum disulfide (MoS2) is proposed. The sensing principle is that the pressure causes the deformation of the polydimethylsiloxane (PDMS) pressure structure above the MoS2 film, leading to the… read more here.
