SYSTEMS AND METHODS FOR FABRICATING WATER-RESPONSIVE ACTUATORS
Water-responsive actuators and methods for creating water responsive actuators are disclosed. In some embodiments, the disclosed subject matter includes a first layer, for example a plastic tape, and a second layer, for example bacterial spores and cured adhesive. The second layer can be created in a pattern. The pattern can include joints, which can contract when exposed to dry air and can thereby bend the actuator, and can expand when exposed to humid air and thereby return the actuator its original position.
