This compliant mechanism achieves motion in response to climatic changes without failure prone electromechanical components.
Completed piece was displayed in controlled climate chamber during ‘+ultra. gestaltung creates knowledge’ exhibition at the Martin Gropius Bau in Berlin. Closed apertures indicate a high R.H.% state.
Translating a hygroscopic bilayer principles for stress induced bending from the pine cone scale to a 4D Printed actuator capable of double curvature and multi-phase motion. The research was based on the Bhutan pine (Pinus wallichiana) cone seed scales as the biological role model.
