Abstract
Disclosed devices may include a membrane having a membrane curvature, a substrate, an enclosure (defined at least in part by the membrane and the substrate) enclosing a fluid, a peripheral structure configured to adjust the membrane curvature, and a sensor configured to provide a sensor signal that is a function of the membrane curvature. The device may also include a controller configured to control the membrane curvature using a control signal. For example, the control signal may be provided to at least one actuator. The controller may receive a sensor signal from the sensor and modify the control signal based on the sensor signal. Examples also include associated methods and systems.
