Abstract: In one example in accordance with the present disclosure, a microfluidic device is described. The microfluidic device includes a reservoir to contain a first thermally expandable fluid, a first heater to heat the thermally expandable fluid in the reservoir, a channel extending from the reservoir and connected to the reservoir at a first opening, and a liquid volume obstructing the channel.

Abstract: A fluidic die may include a number of actuators. The number of actuators form a number of primitives. The fluidic die may include a digital-to-analog converter (DAC) to drive a number of the delay circuits. The delay circuits delay a number of activation pulses that activate the actuators associated with the primitives to reduce peak power demands of the fluidic die. A number of delay circuits may be coupled to each primitive.
