    Abstract: Examples include polymerase chain reaction (PCR) devices. Example PCR devices comprise a fluid input, a fluid output, and a set of microfluidic channels that fluidly connect the fluid input and the fluid output. Each microfluidic channel comprises a reaction chamber, and examples further comprise at least one heating element, where the at least one heating element is positioned in the reaction chamber of each microfluidic channel. The at least one heating element is to heat fluid in the reaction chamber of each fluid channel, and the at least one heating element is to pump fluid to the reaction chamber and from the reaction chamber of each microfluidic channel.

    Abstract: A device for microfluidic transport includes a first fluid reservoir, a second fluid reservoir spaced from the first fluid reservoir, a main fluid channel communicated with the first fluid reservoir and the second fluid reservoir, an auxiliary fluid channel communicated with the main fluid channel, and a fluid actuator within the auxiliary fluid channel asymmetric to the main fluid channel such that operation of the fluidic actuator is to induce fluid flow in the main fluid channel from the first reservoir toward the second reservoir.

    IPC: B41J2/18

    Abstract: A fluid ejection device includes a fluid slot, two laterally adjacent fluid ejection chambers each having a drop ejecting element therein, a fluid circulation path communicated with the fluid slot and each of the two laterally adjacent fluid ejection chambers, and a fluid circulating element within the fluid circulation path, with the fluid circulating element laterally adjacent at least one of the two laterally adjacent fluid ejection chambers, and the two laterally adjacent fluid ejection chambers to substantially simultaneously eject drops of fluid therefrom such that the drops of fluid are to coalesce during flight.
