liquid crystal elastomer gripper (flower?) >
with Ozgun and Lucy’s help, I made an artificial muscle gripper. there was a bit of trial and error and I got most of the way to a functional prototype (the gripper does actuate with heat! but the heating mechanism I ended up integrataing isn’t working very well):
- pla prototypes of different actuation mechanisms
- going back to the drawing board after learning fdm pla is generally too rigid for this stuff
- laser cut some transparency film (probably petg?) into a claw shape
- learned that transparency film was not temperature resistant
- tried laser cutting polyimide (very hard apparently)
- learned that I laser cut the wrong kind of polyimide (had a backer, very thin)
- tried laser cutting thicker polyimide
- used an exacto knife instead
- re-learned that adhesion is hard; roughening necessary to get that
- instead vinyl cut mesh
- print on mesh was a success
- used some resistive felt from adafruit (20ohms/cm^2) for heating element
- ran into issues interconnecting using copper tape
- milled a pcb as a breakout for a 6-pin header
- still ran into issues with interconnects

I made this star trek combadge and COB led driver board awhile back during ecad/efab week:
