A liquid‐crystal elastomer (LCE) iris inspired by the human eye is demonstrated. With integrated polyimide‐based platinum heaters, the LCE material is thermally actuated. The radial contraction direction, similar to a mammalian iris, is imprinted to the LCE by a custom‐designed magnetic field. Actuation of the device is reproducible over multiple cycles and controllable at intermediate contraction...
We propose a lens fabrication process for reaction injection molding of elastomeric micro-lenses. The versatile and flexible process allows manufacturing a broad spectrum of lens shapes, including compound achromatic lenses, entirely consisting of PDMS.
