Abstract
On-platform pumps provide greater flexibility and design freedom and are a key feature of organs-on-chip platforms. On-platform electromagnetic (EM) pumps have been developed for use with the organ-on-chip platforms. The EM pump uses electrical energy, which may be supplied by a battery, making the pump portable. The EM pump uses an EM actuator having a low energy consumption. The actuator's low energy consumption is achieved by a latching design which requires only a short pulse of energy to switch its state and where springs store some of the actuator kinetic energy, which is then recovered in the reverse stroke. This further reduces the energy consumption of the actuator. Also provided are injection-molded, single-use platforms with onboard diaphragm micro-pumps and various valve and pump geometries. The EM actuators easily integrate with these platforms, demonstrating pumping at a constant flowrate, no measurable temperature rise, and valve sealing against varying back-pressure.
