Noliac's standard stacks are designed with 1mm thick PZT endplates on top and bottom of the actuator, and n active single actuators.

Height

The total height of a SCMA can be estimated by the following equation:

H SCMA = n x H CMA + 2

Where: n = number of single actuators constituting the stack H CMA = height of the single actuators constituting the stack [mm]

Example:

Height of a a stack made of 14 CMAP7.

H CMAP7 = 2mm

H SCMA = 14 x 2 + 2 = 30mm

Free displacement at maximum operating voltage

The maximal free displacement dL of a SCMA can be estimated by the following equation:

dL SCMA = 0,9 x n x dL CMA

Where:

n = number of CMA's constituting the SCMA

dL CMA = maximal displacement of the CMAs constituting the SCMA [m]

Example:

Displacement at 3KV/mm of a SCMA made of 14 CMAP7.

Displacement dL CMAP7 =3,1µm

Displacement dL =0,9 x 14 x 3,1E-6 = 39E-6m = 39µm

Note that those equations are only given as an indication. Please refer to Noliac for exact specifications.
