Mechanism
* Many mechanisms also have an energy graph that runs simultaneously.
* Most mechanisms contribute to evolution
  - maternal effects
  - involve receptors
* Most mechanisms lead to matter decomposition
  - ocular defects

  - migratory behavior
  - oocyte growth
  - reproductive behavior
  - convert energy
* Some mechanisms drive extreme weather

### device | mechanism:

Actual mechanism
* Some actual mechanisms involve in reproduction.
* are the detection of chest impedance and of heart rate.

Actuator
* are buttons, dials, sliders, or other mouse-driven symbols
  - devices designed to create motion
  - motors
  - the muscles of every computer-controlled machine
  - uses to control curtains and baffles, inlet valves and dampers
* are, generally, simple devices and include a small amount of intelligence.
* come in three sizes, to move the body, legs and arms respectively.
* have powerful motors with long throw.

### device | mechanism | actuator:

Electrostatic actuator
* allow adjustment of the cavity width between the mirrored surfaces.
* exert a force on a dielectric mirror without touching it.

Hydraulic actuator
* are similar to electric motors in that they position causal.
* move wing aerodynamic control surfaces, a body flap, and the rudder.
* use oil and pneumatic ones use gas to move.

Linear actuator
* are actuators that move in a straight line.
+ Actuator, Linear Actuators: Machines
  * Linear actuators are actuators that move in a straight line. They can be made to move by electricity, or by pushing water or air very hard. Hydraulic systems are used for moving very heavy things, like in cranes, excavators, or bulldozers.

Piezoelectric actuator
* are ideal for high-accuracy positioning systems.
* possess a high power density and are capable of high force output.
* provide nanometer resolution.
