These are usually seen in tiny MEMS devices, and now we have tiny ... For [Nathann]’s Hackaday Prize entry, he’s building electrostatic actuators on the cheap, and not just tiny ones, either.

The eidophor used electrostatic charge to locally deform ... Figure 2: BMC's 4,092-actuator MEMS DM for the Gemini Planet Imager. BMC also produced the first MEMS DMs to be used in civilian ...
