摘要:
A microfluidic device having a reservoir for containing a reagent, an outlet valve in fluid communication with the reservoir, the outlet valve having a meniscus anchor configured to form a meniscus that retains the reagent in the reservoir, and an actuator for receiving an activation signal and actuating in response to the activation signal such that the meniscus unpins from the meniscus anchor and the reagent flows out of the reservoir.

Provided is an inkjet printhead having an array of ink chambers formed on a planar support surface of a wafer substrate. Each ink chamber in the array has a nozzle, a thermal actuator for ejecting ink through the nozzle and a droplet stem anchor. The thermal actuator has two sections with higher resistance than the remainder of the thermal actuator. The droplet stem anchor is positioned between the two sections with higher resistance of the thermal actuator.
