[FMCp4-1] Improved stability of electroactive elastomer tunable lenses
Tunable lens, Head-mounted display, Dielectric elastomer actuator (DEA)
An electrically-tunable lens with dielectric elastomer actuators (DEAs) is designed to change the lens’ focal-length f. The tunable lens can solve the Vergence Accommodation Conflict of the Head-Mounted Display (HMD). The tunable lens varies f by changing the radius of curvature when voltage is applied.
