Use this information to determine what combinations of free length, thickness, width, and applied voltage will provide the deflection or force you need from a Stripe actuator.
To calculate a deflection, compliance, force, or resonance frequency, enter values for the variable parameters in the appropriate brackets, then click on "Calculate". Measured values for Stripe actuators will be within ±30% of the calculated values.

Performance of Stripe Actuators
Note that for all standard Stripe actuators thickness (h) is 0.60 mm.
| Characteristic | Calculation | Result |
| Total Deflection | 2.2 x 10-6x ( [ lf]2 / [ h ]2 ) ( [ V ] ) | [ ] mm |
| Compliance | 26.4 x10-5 x ([ lf ]3/ ( [ w ] ) ( [ h ]3 ) | [ ] |
| Blocking Force | [deflection]/ [compliance] | [ ] N |
| Resonance Frequency | 3.2 x 105x ( [ h ] / [ lf ]2 ) | [ ] Hz |
lf = free length of actuator
h = thickness of actuator (0.60 mm is standard)
w = width of actuator
V = voltage (150 V maximum)
