Abstract: Disclosed is a microfluidic device for simulating organ functions. The microfluidic device comprising a top plate, a bottom plate and a membrane. The top plate comprising a top channel arranged on a first surface of the top plate. The bottom plate comprising a bottom channel arranged on a first surface of the bottom plate, wherein the top channel is overlapping the bottom channel over an entire length of the top channel. The first surface of the top plate and the first surface of the bottom plate are facing each other. The membrane being arranged between the top plate and the bottom plate so that the top channel and the bottom channel are separated by the membrane. The top plate comprises a top channel inlet port being in fluid communication with the top channel.

Abstract: A liquid crystal cell including at least two substrates transparent to visible part of light spectrum, a liquid crystal layer encased between the substrates, and a stack of functional layers formed over the substrates and enclosed between a given substrate and the liquid crystal layer. In a direction from the given substrate towards the liquid crystal layer, said stack comprises a first dielectric layer, a transparent electrode layer, and a second dielectric layer. A refractive index of the first dielectric layer lies in a range between a refractive index of the given substrate and a refractive index of the transparent electrode layer. A refractive index of the second dielectric layer lies in a range between the refractive index of the transparent electrode layer and a refractive index of the liquid crystal layer corresponding to a homeotropic alignment of a liquid crystal material of the liquid crystal layer.
