Claim Text:
1. A microfluidic cartridge comprising: a fluid-holding reservoir comprising an outlet; a microfluidic channel configured to receive fluid from the fluid-holding reservoir through the outlet; a printed circuit board; a via positioned in the printed circuit board such that the via is positioned under, over, or adjacent to the outlet of the fluid-holding reservoir; a valve comprising a phase-changeable material, wherein: a heating element configured to heat the via such that the via heats the phase-changeable material deposited on the via to transition the phase-changeable material from the first state to the second state to permit the fluid to flow from the fluid-holding reservoir through the outlet and into the microfluidic channel; and a cartridge housing configured to enclose the fluid-holding reservoir, the microfluidic channel, the printed circuit board, the via, the valve, and the heating element.
