Abstract

A microfluidic device includes first and second substrate structures. The first substrate structure has a first substrate surface configured to receive one or more droplets. A plurality of electrodes configured to apply an electric field to the droplets. The second substrate structure has a second substrate surface facing the first substrate surface and spaced apart from the first substrate surface to form a fluid channel. The microfluidic device has a first heating element adjacent to the first substrate structure and disposed on an opposite side of the first substrate surface, and a second heating element adjacent to the second substrate structure and disposed on an opposite side of the second substrate surface. The microfluidic device further includes one or more temperature sensors disposed adjacent to the fluid channel between the first substrate structure and the second substrate structure.
