Fig. 3From: A silver nanowire-based flexible pressure sensor to measure the non-nutritive sucking power of neonatesa Customized evaluation setup to characterize the pressure sensing device and b working principle of the setup to measure the pressure and the change in resistance of the sensor. When the piston is displaced by the Z-axis motorized stage, the negative gauge pressure generated inside the cylinder is measured by a pressure data logger, and the change in resistance of the sensor due to deformation is measured by an LCR meterBack to article page
