 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.

FT-G Microgripper

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.

Manifold Air Pressure Sensor

The MAP sensor (Manifold Air Pressure Sensor) is a main input to the ECM or engine computer. The MAP sensor measures the difference in air pressure between the intake manifold and atmospheric pressure. The ECM infers engine load from the MAP sensor reading.The MAP sensor converts engine vacuum and boost pressure into a varying output voltage, between 0-5 volts.

Manifold: The primary function of the intake manifold is to evenly distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). Even distribution is important to optimize the efficiency and performance of the engine. (source: wikipedia)
