An apparatus to pump a fluid includes a housing (106) extending along an elongated interior (118), an actuator (102) in the housing (106), conforming to the elongated interior (118), the actuator (102) including a plurality of lumens (120), each extending substantially parallel to the elongated interior (118), each from around 10 to 200 micrometers across, and an actuator drive (104) configured to oscillate the actuator (102) in the actuator housing (106) along the elongated interior (118) with a rate differential between movement in a first direction (112) versus movement in a second direction (114) opposite the first direction to pump the fluid. |
