A sample of PPY-PVDF-PPY trilayer actuating in electrolyte solution. Voltage 3-6v, current about 1-2 milliamperes. At the end, it actuates in air, and lifts about 1/8th of a gram (it lifted about a gram maximum, but I didn't get that on video). The total PPY thickness is 30 microns. The sample is 1mm wide. Its strength per cross section area, ignoring displacement, is 5-10 times that of human muscle.
It would be cool if you did this experiment again and got more on video while describing all the stuff. you can just mute it when displaying.
