PICMA® Technology
relative humidity (test conditions: PICMA® stack and polymer-coated actuators, dimensions: 5 × 5 × 18 mm³, 100 V DC, 22 °C, 90 % RH) Leakage Current Leakage current measurements impressively demonstrate [...] actuators. Preloaded PICMA® actuators, sized 5 mm × 5 mm × 36 mm, were operated at room temperature with compressed air cooling, with a sinusoidal signal of 120 V unipolar voltage at 1157 Hz, which equals [...] Operating voltage in V | A T Temperature in °C | A F Relative humidity (RH) in % With decreasing voltage values the lifetime increases exponentially. For example, the expected lifetime at 80 V (DC) is ten times
