SQUIGGLE Motors for Micro-Scale Fluid Control
Micro pump is 10x smaller with higher
precision, no pulsation
Micro pumps are designed to move microliter and nanoliter volumes of fluid in a
precisely controlled manner. Applications include:
- Lab-on-a-chip systems: integrating laboratory functions,
such as blood analysis or contaminant detection, on a single
chip using extremely small fluid volumes
- Drug delivery devices: pumps and syringes
- Micro fuel cells
- IC cooling: pumping fluids through micro-channels on
integrated circuits
- Micro lubrication systems: using fine mist rather
than a flood of lubricant, reducing waste
- Spacecraft thrusters
- Liquid optics: controlling the fluid to focus the liquid lens
Most micro pumps today employ flexing diaphragms and peristaltic
motion. This creates pulses of uneven pressure. Flow precision
depends on the backpressure.
A micro pump design based SQUIGGLE motors overcomes these
limitations. New Scale's reference design uses
the SQUIGGLE motor's precise linear motion to directly move a
reciprocating piston or bellows. This positive displacement pump
design enables higher precision, pressure and flow in a package that
is one tenth the size of existing micro pumps. The SQUIGGLE motor-based micro pump
offers:
- Sub-nanoliter flow resolution
- Smooth flow without pulsation
- Flow precision independent of backpressure
- Low sensitivity to bubbles and particles
- Scaleable pressure and flow rate
- Self priming
- Size smaller than a pen cap
(one tenth the size of competitive designs)
- Lowest power
- Low cost in high volumes
