Abstract
A microfluidic refill includes a reservoir having a hollow body and an opening; a transport member in fluid communication with the reservoir; and a lid enclosing the opening of the reservoir. The lid is in fluid communication with the transport member. The lid comprises a rigid microfluidic delivery member. The rigid microfluidic delivery member includes a die and electrical traces that are in electrical communication with the die, wherein the electrical traces terminate at electrical contacts, wherein the electrical traces are disposed on only one plane. The die has a fluid chamber in fluid communication with the transport member at an inlet of the fluid chamber and with an orifice at an outlet of the fluid chamber and.
