The thermal responsive emulsion is injected into a micro centrifuge chip’s chamber. The centrifuge force is 450g and the temperature is 45℃ which is already over its LCST. So coalescence occurs. We can follow coalescence by tracking area change and droplets’ change with a homemade Matlab script. This technology may offer a visual and efficient way to under coalescence mechanism.
