Testing the actuation with high voltage electricity and material properties of the membranes at the same time. Membranes appear to be very sensitive to voltage above 4kV. They tend to damage quite easily. Actuation usually starts around 1.3 / 1.5 kV. Discharging capacitor and converter is done manually, via bleeder resistors board. Capacitor should store electric charge after it is switched off for certain time. After that moment it should discharge gradually and the time of discharge should be influenced by outer level of humidity and the conductivity of the capacitor itself. This could be an interesting moment in the behavior of an array of capacitors being switched on and off. 042 045 044 test object 047 048 membrane elasticity testing
