A review of micropumps
A pump using three piezo transducers in a peristaltic firing order.
Transducers are driven by three square waves, 60 degrees out of phase.
Square wave is +35V -35V (70Vpp) and draws 3mA.

Tiny robotic hand has the gentlest touch
Tiny robotic hand has the gentlest touch
A tiny pair of robotic tweezers with the most sensitive grip yet can
pick up and move individual cells without damaging them, guided by their
own sense of touch. They could be used to probe the properties of
living tissue, or create microscale and nanoscale devices.

The
FT-G Microgripper series is designed to handle micro- to
nanometer-sized objects. The initial openings of the gripper arms are 30
μm, 60 μm and 100 μm (respectively customizable up to 400 μm). The
opening can be controlled with nanometer precision, such that the
gripper arms are fully closed upon applying the maximum actuation
voltage.
